Prevalence and predictors of detrusor underactivity and bladder outlet obstruction in women with lower urinary tract symptoms

This study aims to present age-stratified prevalence of women with lower urinary tract symptoms (LUTS) but without cystocele and predict detrusor underactivity (DU) or bladder outlet obstruction (BOO). Between 2005 and 2020, we reviewed women who visited the medical center with LUTS but without cystocele. Positive voiding dysfunction (VD) symptoms were defined as any one or more of the positive descriptions of weak urinary stream, intermittency, strain to urination, and sensation of not emptying. A total of 1,886 women were included in this study. 189 (10.0%) women were diagnosed with DU, and 77 (4.1%) women had BOO. Multivariate logistic regression analysis found that voided volume and VD symptoms were independent predictors for BOO. ROC curve analyses could predict BOO by voided volume ≤ 220 mL derived from uroflowmetry and the presence of VD symptoms with an area under a curve of 0.83. Age and voided volume could predict DU with an area under a curve of 0.82. We found a higher percentage of BOO in women with positive VD symptoms. A non-invasive uroflowmetry with voided volume (≤ 220 mL) and the presence of VD symptoms can predict BOO. DU could be predicted by age and voided volume.

The Diagnostic Value of bpMRI in Prostate Cancer: Benefits and Limitations Compared to mpMRI.

Prostate cancer is the second most common cancer in men and a leading cause of death worldwide. Early detection is vital, as it often presents with vague symptoms such as nocturia and poor urinary stream. Diagnostic tools like PSA tests, ultrasound, PET-CT, and mpMRI are essential for prostate cancer management. The PI-RADS system helps assess malignancy risk based on imaging. While mpMRI, which includes T1, T2, DWI, and dynamic contrast-enhanced imaging (DCE), is the standard, bpMRI offers a contrast-free alternative using only T2 and DWI. This reduces costs, acquisition time, and the risk of contrast-related side effects but has limitations in detecting higher-risk PI-RADS 3 and 4 lesions. This study compared bpMRI's diagnostic accuracy to mpMRI, focusing on prostate volume and PI-RADS scoring. Both methods showed strong inter-rater agreement for prostate volume (ICC 0.9963), confirming bpMRI's reliability in this aspect. However, mpMRI detected more complex conditions, such as periprostatic fat infiltration and iliac lymphadenopathy, which bpMRI missed. While bpMRI offers advantages like reduced cost and no contrast use, it is less effective for higher-risk lesions, making mpMRI more comprehensive.

Posterior urethral valves: Clinical audits of presentation, diagnostic and therapeutic intervention in a nigerian teaching hospital.

We described our experience in the management of PUV at UNIOSUN Teaching Hospital, Osogbo, Osun State. This was a retrospective analysis of patients with diagnosis of PUV carried out over a 4year period (2019-2023). Demographic characteristics, clinical presentation, diagnosis and mode of therapeutic interventions were the variables analysed. A total of 17 patients with PUV were managed during the study period. Median age at presentation and surgery were 10months (range 3.0-48.0) and 13months (range 3.0-49.5), respectively. Most common presentation was poor urinary stream, 11 (64.7%). Mean PCV was 34.42%. Klebsiella aerogens was the predominant 9 (52.9%) organism isolated. A patient had prenatal USS diagnosis suggestive of PUV, majority (52.9%) had bilateral grade 1V hydronephrosis at presentation. Voiding cystogram was diagnostic in 14 patients, (82.4%) while urethrocystoscopy was done in 14 (82.4%) patients. Median creatinine level were 116, 76.5 and 51.0 (micromol/l) pre- and post-catheterization and 1month post-surgery, respectively. There was positive correlation between the age and post- surgery creatinine but a negative correlation between the PCV and grade of hydronephrosis. All patients had Mohans valvotomy. We had mortality in a patient from urosepsis. At 6months-1year follow-up, 15 patients had good urine stream with stable renal function. Early intervention assist in optimizing renal and bladder function and minimize risk of urosepsis. Where there is no facility for endoscopic valve ablation, Mohans valvotomy remains a viable treatment option.

Anterior deflected urinary stream in female children: description of a unique clinical entity and surgical management.

To investigate the clinical presentation and outcomes for a series of female pediatric patients with severe anterior deflection of the urinary stream (ADUS) who were managed via urethromeatoplasty. This single institution retrospective cohort study used the institutional billing database to identify female patients ≤18 years who received a urethromeatoplasty (CPT 53450) from 2007 to 2022. Patients were included if a substantial anterior deflection of their urinary stream was the primary indication for surgery. Patients were excluded if they were >18 years of age, had a history of prior genital trauma, or underwent surgery for an indication other than a deflected urinary stream. Twenty female patients underwent urethromeatoplasty between 2007 and 2022, with a median age of 3 years old. All patients presented with difficulty aiming the urinary stream during toilet training and demonstrated a web of tissue along the posterior aspect of the urethral orifice. 19/20 patients noted immediate response (i.e., normal, non-deflected urinary stream) after the urethromeatoplasty with no further urinary complaints. There were no post-operative complications within a 90-day period. ADUS is a clinical entity characterized by a web of deflecting tissue at the female posterior urethral meatus that causes severe urinary deflection without other urologic symptoms. This is not well-described in the literature. Surgical correction via urethromeatoplasty is safe and effective.

Retrograde Progression of Inner Preputial Skin to Overcome Skin Shortage in Cases of Congenital Buried Penis.

The aim of this study is to report our experience in the treatment of congenital buried penis using a simplified technique of retrograde progression of inner preputial skin for reconstruction and overcome skin shortage. This is a retrospective multi-institutional study conducted in the Department of Pediatric Surgery, I Q City Medical College and Hospital, Durgapur, West Bengal, India, and the Department of Paediatric Surgery, Rajiv Gandhi Super Specialty Hospital/Raichur Institute of Medical Sciences, Raichur, Karnataka, India, over a period of 3 years (from March 2019 to February 2022). A total of 14 cases of primary congenital buried penis were operated in the specified period. Age of the patients ranged between 8 months and 9 years. Retrograde progression of the inner preputial skin to provide coverage to the dorsal aspect of penile shaft and ventral transposition of the dorsal penile skin to cover the ventral penile shaft was used as a standard procedure for skin coverage. All patients had good-to-excellent outcomes with uniformly improved visualisation of penile shaft post-operatively. There were no significant post-operative complications apart from mild oedema which subsided over a period of 3 weeks. Genital hygiene had significantly improved in all the patients as a result of uninterrupted urinary stream. Retrograde progression of the inner preputial skin may be used as an effective technique to provide skin coverage to the penile shaft for reconstruction of congenital buried penis. It provides good functional and cosmetic results with adequate parental and patient satisfaction with minimal complications.

Comparative Outcomes of Monopolar and Bipolar Transurethral Resection of the Prostate: An Institutional Perspective.

Objective This prospective comparative study aimed to highlight and compare two types of transurethral resection of the prostate (TURP), namely M-TURP (monopolar) and B-TURP (bipolar), in the endoscopic management of benign prostatic hyperplasia (BPH). Methods and materials This research was conducted between 2022 and 2023 at a tertiary care health center. Included in the investigation were 100 consenting study participants undergoing M-TURP and B-TURP at our center. All referred patients presenting with clinical, ultrasound, or uroflowmetry features of BPH and those with failed attempts at medical management were included in the study. Patients with carcinoma of the prostate were excluded from the study. Post-operatively, the endpoints for comparison included maximal urinary flow rate (Qmax), prostate volume, duration of hospital stay, duration of catheterization, drop in serum sodium concentration, and drop in hemoglobin levels. Descriptive statistics were computed to delineate the study sample. After the completion of data collection, data analysis was performed using SPSS for Windows, Version 16.0 (Released 2007; SPSS Inc., Chicago, IL, USA), and the correlations sought were achieved using the Chi-square test of significance. Results The peak incidence of BPH was seen in the sixth decade of life: the M-TURP group was 65.16 ± 7.07 years (mean ± standard deviation), while that in the B-TURP group was 62.32 ± 8.16 years (mean ± standard deviation). Nine percent of the study participants did not show any comorbidities. The most frequent symptom of BPH at presentation was a poor urinary stream (78%, n = 100), followed by nocturia (67%, n = 100). In our study, patients undergoing M-TURP had a mean serum prostate-specific antigen (PSA) level of 4.31 ± 1.03 ng/mL, while patients undergoing B-TURP had a mean serum PSA of 4.24 ± 0.99 ng/mL (p = 0.820; p > 0.05). The study found that patients undergoing M-TURP had a mean prostate size of 35.04 ± 3.57 cc, while those undergoing B-TURP had a mean prostate size of 35.72 ± 3.22 cc (p = 0.765). For the B-TURP group, the mean decrease in postoperative serum sodium concentration was 4.3 mEq/L, while for the M-TURP group, it was 6.4 mEq/L (p = 0.903). In the M-TURP group, there were three cases of transurethral resection (TUR) syndrome, while the B-TURP group had only one case. Conclusion BPH is a common problem affecting the quality of life of several male patients. Both M-TURP and B-TURP are comparable in their efficacy in treating BPH, with the exception of a higher incidence of hyponatremia and TUR syndrome in the M-TURP group.

Real-world experience with the new pulsed solid-state Thulium: YAG laser (Thulio) for endoscopic enucleation of the prostate

PurposeThe solid-state Thulium laser (Tm: YAG) is a novel alternative to the widely used Holmium laser for endoscopic enucleation of the prostate (EEP) due to its relatively high peak power. The aim of this study was to examine the efficacy and safety of a new pulsed Tm: YAG laser in its first application in humans.MethodsData were retrospectively collected for the first 103 patients who underwent EEP with a new pulsed solid-state Tm: YAG laser (Thulio®, Dornier MedTech Systems GmbH, Weßling, Germany). Peri- and postoperative data were assessed. Procedure-specific complications were graded using Clavien-Dindo Classifications (CDC). Patients were interviewed 15 months after the surgery to evaluate functional and long-term outcomes. Statistical analysis was performed with Statistical Package for the Social Sciences (SPSS®).ResultsThe mean preoperative prostate volume was 105.6 ± 55.0 ml. Median enucleation speed was 4.1 g per minute (range 1.1–9.7). Short-term postoperative complications occurred in 21 patients (20.4%), but no high-grade complications (CDC ≥ IV) were observed. Five patients suffered gross haematuria and required reintervention (CDC IIIb; 4.9%). After 15 months, 76 patients (73.8%) participated in the follow-up interview, where seven patients (9.2%) reported complications, including two reinterventions for urethral strictures (CDC IIIb; 2.6%). Most patients reported an improvement in continence (54.0%) and urine stream (93.4%), but no difference in erectile function (81.6%). No persistent dysuria was reported. Patient satisfaction with the surgery results was very high (96.1%).ConclusionEndoscopic enucleation of the prostate with the new pulsed solid-state Tm: YAG laser is a safe and effective option for surgical BPH treatment.Trial registrationGerman Clinical Trials Register number: DRKS00031676.

Asymptomatic Bacteriuria among Pregnant Women Attending Antenatal Care

The complication associated with bacteriuria during pregnancy not only result increase morbidity of the mother but also have detrimental effects on the fetus which may result in preterm labor, fetal growth retardation, hypertension and anemia. Studies have shown that the fetal mortality rate was 2.4 times higher than in pregnancy associated with urinary tract infection.This study conducted to determine the prevalence of asymptomatic bacteriuria in pregnant women. A cross-sectional study carried out during the year 2017 at a tertiary care hospital Alkhadra in Tripoli/Libya. 200 pregnant women aged between 19-43 years attending the obstetrics and gynecology clinics were included in this study. From these patient’s mid- stream clean catch urine samples were collected and processed. The following information were obtained from the patients; demographic data, parity, abortion history, history of UTI, history of DM, Urine culture result, type of organism. The minimum age was 19 years and the oldest was 43 years old. The mean maternal age of the cases was 29.2 ± 3.1 years. The multiparous cases were 61% and 48% of women had positive history to UTI before the study, also only 4% of cases were diabetic, regarding the time of diagnosis 18% were diagnosed at first trimester and 46% at the 2nd trimester while 36% diagnosed at the 3rd trimester. Regarding the urine culture results only 23% of cases had significant bateriuria and 8% had insignificant bateriuria, 14% the result was contaminated and 55% of cases their results were sterile, E. coli was the most predominant organism in the current study. The prevalence of asymptomatic bacteriuria in pregnant women (23%) was comparable with similar studies in other countries. The most common uropathogens isolated in this study were E.coli followed by K. pnuemoniae.

A Smart Computer Program to Assist Healthcare Providers in Selecting the Best Treatment for Patients with Urinary Stones

Urinary tract stones can obstruct the urinary tract, resulting in severe lower back pain, blood in the urine, vomiting, and painful urination. While small stones can pass naturally through the urine stream, larger ones necessitate fragmentation with shock wave lithotripsy (SWL) or laser ureterorenoscopy (URS) to prevent urinary tract blockage. A smart computer program was developed to predict treatment efficacy and potential complications for individual patients based on factors such as age, health conditions, stone details, and treatment methods, ultimately recommending the most suitable option. Here, I present three case studies and their predicted outcomes.

In-Vitro Study of The Effect of Celosia argentea And Boerhaiva diffusa Root Plant Extracts on Calcium Oxalate Crystals

Since ancient times, people have used plants to treat illnesses. Urolithiasis has been a problem for people worldwide for thousands of years. Nature has given our country a huge range of plants that can be used as medicine. Medicinal plants have been used for hundreds of years because they are safe, effective, culturally acceptable, and don't have as many bad side effects as manufactured drugs. Crystals in the urinary stream separate from urine and form kidney stones.

Efficacy comparison between Mathieu combined urethral plate incision and onlay island flap urethroplasty for distal hypospadias in patients with urethral plate stenosis.

The aim of the study was to compare the efficacy of Mathieu combined urethral plate incision (Mathieu-IP) versus onlay island flap urethroplasty in patients with distal hypospadias complicated by urethral stenosis. The clinical data of 70 patients with distal hypospadias complicated by urethral plate stenosis treated in the Department of Urology, Anhui Provincial Children's Hospital (Hefei, China), from May 2019 to May 2022, were retrospectively analyzed. Thirty-eight patients underwent Mathieu-IP (Mathieu-IP group) and 32 underwent onlay island flap urethroplasty (Onlay group). Follow-ups at 1 month, 6 months, and 12 months postoperatively assessed operative time, complications, urethral meatus morphology, and family satisfaction. The Mathieu-IP group had significantly shorter operative time (mean ± standard deviation [s.d.]: 81.58 ± 5.18 min) versus the Onlay group (mean ± s.d.: 110.75 ± 6.05 min; P < 0.05). Surgical success rates were 78.9% (Mathieu-IP group) and 75.0% (Onlay group), with no significant difference ( P > 0.05). Complications were comparable between the groups. The Mathieu-IP group resulted in a vertical slit-shaped urethral meatus in 89.5% versus 13.8% in the Onlay group ( P < 0.05). Family satisfaction with general penile appearance and skin shape showed no significant differences, but the Mathieu-IP group had higher satisfaction with meatal position ( P < 0.05). Mathieu-IP offers simplicity, safety, and shorter operative time compared to Onlay. Both the techniques effectively treat urethral plate stenosis in distal hypospadias, with reduced postoperative complications compared to tubularized incised plate urethroplasty. Mathieu-IP results in a vertical slit-shaped urethral meatus which enhances urinary stream, indicating its potential for broader adoption.

Urethral multiplicity in boys: systematic review of case reports and case series from the last 15 years.

Urethral multiplicity is a rare congenital anomaly characterized by the presence of two or more urethral channels. It is more common in males and can cause double urinary stream, incontinence, obstruction, and recurrent urinary infections. Diagnosis is difficult due to diverse clinical manifestations. Implementing an evidence-based treatment plan is challenging due to the need for more concise and informative summary publications. Our paper provides a comprehensive review of the management of this pathology and might serve as a valuable resource for pediatric urologists and specialists in the field. A comprehensive search in four electronic databases, PubMed®, PubMed Central® (PMC), Scopus, and Clarivate Analytics's Web of Science (WoS), was conducted to identify case reports and series published between 2008 and 2023 on urethral multiplicities. The quality of the articles was assessed using qualified instruments. Covidence® tool-guided synthesis was followed by individual patient data extraction. Further classifications and analysis were made using Microsoft Excel®. Out of the 90 papers included in the review, 62 were case presentations, and 28 were case series. We found 250 boys with urethral multiplicity. Based on Effman's classification, there were 38 cases of type I (15.3%), 21 type IIA1 (8.4%), 55 type IIA2 (22.1%), 91 type IIA2Y (36.5%), 4 type IIB (1.6%), and 6 type III (2.4%) urethral duplications. There were 19 cases of prepubic sinuses (7.6%), 9 triplications (3.6%), and 6 unknown forms (2.4%). We have provided data for each type, including clinical presentation, investigations, surgical management, and outcomes. Urethral multiplicities are a rare and varied group of malformations that require high-quality imaging examination for successful management. Treatment is specific to each patient and may depend on the surgeon's preference or skill. https://www.crd.york.ac.uk/prospero/display_record.php?ID = CRD42023471685, identifier (CRD42023471685).

Self-Assessment of Lower Urinary Tract Condition in Female Competitive Cyclists.

During cycling, prolonged compression by the bicycle saddle on the anatomical structures located in the perineum area occurs. An additional factor that may have a negative impact on organs located in the pelvic area may be a prolonged sitting position resulting in increased intraabdominal pressure. This situation has the potential to adversely affect pelvic floor function. Therefore, the aim of this study was to assess the incidence of lower urinary tract symptoms (LUTSs) in female competitive road cyclists and cross-country cyclists. The study included 76 female competitive road cyclists and cross-country cyclists and 76 women not practising competitive sport. The Core Lower Urinary Tract Symptom Score (CLSS) questionnaire was used to assess the lower urinary tract condition. Female competitive cyclists had a statistically significantly higher LUTSs score (95% CI: 3.12-4.2 vs. 2.31-3.16; p < 0.05) compared to women not practising competitive sports. Female cyclists had a statistically significantly higher overall CLSS score (95% CI: 3.99-5.61 vs. 2.79-3.97; p < 0.05). Female cyclists had a statistically significantly higher incidence and severity of urinary frequency (p < 0.05 and p < 0.02), urge (p < 0.001 and p < 0.02) and stress incontinence (p < 0.001 and p < 0.001), and pain in the bladder (p < 0.01 and p < 0.01), while physically inactive women recorded a statistically higher incidence of slow urinary stream (p < 0.01 and p < 0.04). A statistically significant association was recorded between the years of cycling and the number of hours per week spent on training and the number of symptoms and their severity. The number of natural births experienced by women involved in competitive cycling significantly affects the severity of LUT symptoms. Compared to women not practising competitive sports, competitive female cyclists are found to have a higher prevalence of LUTSs and a greater degree of severity. LUTSs in competitive female cyclists are negatively influenced by years of competitive career and weekly number of training hours and the number of natural births experienced.

Disseminated gonococcal infection: A case report of gonococcal polyarthritis

Neisseria gonorrhoeae (N. gonorrhoeae) is a sexually transmitted pathogen and its dissemination can lead to a variety of clinical signs and symptoms, such as arthralgias and arthritis. We report a case of an immunocompetent, 20-year- old patient with purulent arthritis due to disseminated gonococcal infection (DGI). Before discharge diagnosis, the patient was treated for rheumatoid arthritis, which worsened his clinical condition and delayed diagnosis. On further questioning, the patient reported urethral discharge, then the causative agent was identified by performing a PCR on the first stream of urine which came back positive for Neisseria gonorrhoeae. This case’s aim is to demonstrate an infrequently seen manifestation of Neisseria gonorrhoeae, since the incidence of N. gonorrhoeae infections has increased in recent years, and to highlight the need for awareness of extragenital manifestations of gonococcal infection especially in young adults.

#1654 Infectious complications after kidney transplantation: a retrospective study

Abstract Background and Aims Infection is a major cause of morbidity among kidney transplant recipients. Allograft rejection is a frequent cause of dysfunction and its treatment increases the risk for both common and opportunistic infections. Nevertheless, its exact impact on infection incidence and further worsening of allograft dysfunction is not fully known. We aimed to characterize the incidence, nature, and severity of infectious complications following kidney transplantation, their association with previous rejection and its impact on allograft function. Method This was a single center retrospective study covering all patients transplanted between July 2021 and June 2023 in a tertiary referral center. Demographic and clinical data were collected from patient records, including donor and patient features, graft function over time and occurrence of either infection or rejection. Logistic regressions were adjusted considering sex, age, blood type and presence of diabetes as independent variables. Results A total of 139 patients were considered, 49 (35.3%) were women and 90 (64.7%) were men. Mean age was 49.6 ± 13.0 years. Median follow-up time was 375 [194-596] days. The main cause of renal disease was diabetes (37 patients, 26.8%) and most patients (113; 81.9%) were on hemodialysis for a median vintage of 3 [2.3] years. Considering the 139 transplants performed, 113 (81.2%) were isolated kidney, 24 (17.4%) were simultaneous kidney-pancreas and 2 (1.4%) were simultaneous kidney-liver transplantation. Eleven (7.9%) were living donor. During follow-up time, in-hospital infection occurred in 34 (24.4%) patients, mostly urinary (13, 38%) and blood stream (11, 32%) infections. These events significantly delayed hospital discharge (15.88 ± 8.52 vs 26.05 ± 14.3 days, p-value=0.001). During the follow up, a total of 107 (77%) patients developed 220 infection episodes leading to 47 hospital admissions. Urinary infections (64, 28.8%) and cytomegalovirus (CMV) viremia (64, 28.8%) were the most common at median follow-up time of 85.5 [40.25-183.75] and 159 [43.25-258.5] days, respectively. Median timing of diagnosis was 400.8 [203-614] days after transplant. They were much more common during the first three months (0.014 vs 0.002 per follow-up day). There were no differences in infection incidence between type of donor (p=0.76), type of allograft (p=0.361), immunosuppression protocol (thymoglobulin or basiliximab, p=0.45), renal replacement therapy or presence of diabetes. Regarding urinary infections, days of urinary catheterization (p=0.905), need for catheter replacement (p=0.092) or presence of residual diuresis (p=0.375) had no impact on infection rates. A positive correlation was found, between the number of infection episodes and creatinine increase over the first year (r=0.386; p&amp;lt;0.000). Allograft rejection was diagnosed and treated through protocol biopsy in 25 (18%) cases. These patients presented 17 confirmed episodes of infection over the three following months. Nine of them (36%) were CMV detectable viremias. Patients with a history of rejection had significantly more infections (1.49 ± 1.22 vs 2.20 ± 1.26, p=0.01), even after adjustment (p=0.006). Conclusion Early infections after kidney transplantation negatively impact hospital length of stay and allograft function. Furthermore, immunosuppressive treatment of allograft rejection carries a higher risk of infection. Further research is needed to clarify the impact of specific subsets of allograft rejection and immunosuppression protocols on the incidence of various types of infectious complications which could impair short-term renal function.

Anterior Sagittal Epispadias Urethral Duplicity: A Case Report

Urethral duplication is a rare congenital urological anomaly that can be detected incidentally or due to urinary symptoms in young patients. Symptoms may include recurrent urinary tract infections, dysuria, bifurcated urinary stream, urinary incontinence, and purulent discharge from the accessory meatus. The pathophysiology remains poorly understood, with various embryological theories proposed. Treatment typically involves surgical excision of the accessory urethra, especially in symptomatic cases. Urethral duplication is often associated with other malformations, and Effman's classification system categorizes it into three types based on the location of the accessory urethra. We present the case of a 4 years old boy with anterior sagittal epispadias urethral duplicity.

Stone decision engine accurately predicts stone removal and treatment complications for shock wave lithotripsy and laser ureterorenoscopy patients.

Kidney stones form when mineral salts crystallize in the urinary tract. While most stones exit the body in the urine stream, some can block the ureteropelvic junction or ureters, leading to severe lower back pain, blood in the urine, vomiting, and painful urination. Imaging technologies, such as X-rays or ureterorenoscopy (URS), are typically used to detect kidney stones. Subsequently, these stones are fragmented into smaller pieces using shock wave lithotripsy (SWL) or laser URS. Both treatments yield subtly different patient outcomes. To predict successful stone removal and complication outcomes, Artificial Neural Network models were trained on 15,126 SWL and 2,116 URS patient records. These records include patient metrics like Body Mass Index and age, as well as treatment outcomes obtained using various medical instruments and healthcare professionals. Due to the low number of outcome failures in the data (e.g., treatment complications), Nearest Neighbor and Synthetic Minority Oversampling Technique (SMOTE) models were implemented to improve prediction accuracies. To reduce noise in the predictions, ensemble modeling was employed. The average prediction accuracies based on Confusion Matrices for SWL stone removal and treatment complications were 84.8% and 95.0%, respectively, while those for URS were 89.0% and 92.2%, respectively. The average prediction accuracies for SWL based on Area-Under-the-Curve were 74.7% and 62.9%, respectively, while those for URS were 77.2% and 78.9%, respectively. Taken together, the approach yielded moderate to high accurate predictions, regardless of treatment or outcome. These models were incorporated into a Stone Decision Engine web application (http://peteranoble.com/webapps.html) that suggests the best interventions to healthcare providers based on individual patient metrics.

Benign Prostate Hypertrophy: An Educational Ultrasound Images and Pharmacotherapy Mini-Review

Background: A benign increase in the size of prostate (Enlargement) can be asymptomatic, but it can cause symptoms resulting from pressure on the urethra, including frequency of urination, difficulty in starting urination, poor urine stream, dribbling after urination, and inability to pass urine. Ultrasonography has been used as early as 1971 for the diagnosis of prostatic enlargement. Patients and Methods: The case of a 53-year old diabetic and hypertensive male who had refractory psoriasis and developed benign enlargement is described and an educational ultrasound images are presented. Results: The patient was complaining of dribbling after micturition for few weeks. He was not having difficulty in starting urination nor complained of frequent micturition, and the urine stream was considered normal. The urinary bladder was normal, but with mild hazy wall outline. Pre-voiding volume was 248 ml, and post-voiding volume was 9 ml. Ultrasound of the prostate showed enlarged prostate with homogenous texture. Prostate volume was 36.6 ml (Normal: 25 ml). Therefore, Oral finasteride was started. Conclusion: Many medications have been used in the treatment of benign enlargement of the prostate during the 1960s, 1970s, and 1980s, including progestational agents, Amino acids, spironolactone, candicidin, nystatin, flutamide, bromocriptine, alpha-adrenergic blockers, Serenoa repens (Saw palmetto extracts), and mepartricin. However, the current evidence-based opinion suggests that benign enlargement of the prostate can be initially treated with medications that can reduce the volume of the prostate such as finasteride and dutasteride. Tamsulosin or alfuzosin can be added to further improve lower urinary symptoms.

Pain in the enthesis of levator ani muscle: A novel source of chronic pelvic pain.

Managing chronic pelvic pain (CPP) remains a challenge due to its diverse range of causes. A newly identified anatomical entity known as the enthesis of the levator ani muscle (LAM) and its associated disorders might play a role. This paper describes a novel insight into CPP's origin, aiming to improve accurate diagnosis and treatment. Data were collected from medical records (paper or electronic) retrospectively. The study included 112 patients meeting the criteria, divided into CPP and non-CPP groups. Clinical symptoms, including location of LAM enthesis, referred pain from pain in LAM enthesis, and related lower urinary tract symptoms (LUTSs) were discussed. To identify differences in symptoms between the groups, a Chi-squared test and descriptive analyses were conducted. Bimanual examination revealed tender sites in the attachment of the LAM to the pubic bone. LAM enthesis pain presumably caused referred pain in at least 10 areas, primarily in the lower abdominal quadrate (40.2%-47.3%) followed by the inguinal area (8.9%-15.1%). Multiple LUTSs were observed, including urinary frequency (72.3%), urgency (42.9%), nocturia (53.6%), residual urine sensation (64.3%), urinary incontinence (30.3%), painful bladder (34.8%), and weak urine stream (47.9%). Patients in the CPP groups experienced significant residual urine sensation (53.6%) and bearing-down sensation (42%) compared to the non-CPP group. Pain in LAM enthesis is a novel cause of pelvic pain and LUTSs that warrants attention for the evaluation and management of CPP.

Sacrococcygeal teratoma: an experience from a high-volume tertiary institute in North India

Background: Sacrococcygeal teratoma (SCT) is the most common tumour in the newborn. The majority is present in neonates as a sacral mass; however, some may be present late with varied clinical presentation. The study aims to evaluate the clinical presentation and management of patients with SCT in our high-volume tertiary institute in North India. Methods: This is an observational study of infants and children treated between May 2021 to April 2022 in the department of pediatric surgery, SMS Medical College, Jaipur (a high-volume tertiary institute in North India). Data collected included antenatal diagnosis, mode of delivery, age at diagnosis, clinical presentation, Altman classification, surgical approach, histopathology and complications. Functional results were evaluated clinically and radiologically. Results: Twenty-one patients (M: F=1:3.2) with a median age of 40 days (range: 1 day to 5.8 years) with SCT were managed at our centre. Nearly, two-thirds of the tumors were either Altman type 1 or 2. Yolk sac tumour was present in 2 (9.5%) patients, while the rest had either mature or immature teratoma. Tumours were removed through a posterior sagittal approach (chevron incision). In five patients, an abdominoperineal approach was used. Early complications were surgical site infection (n=5; 23.8%), superficial wound dehiscence (n=2; 9.5%), complete wound dehiscence (n=1; 2.4%), and urinary tract infection (n=1; 4.7%). Late complications were urinary dribbling or poor stream (5/21; 23.8%) and faecal soiling (n=3; 14.2%). Conclusions: Most of the sacrococcygeal tumours are benign, and the incidence of malignancy increases with age. Morbidity due to associated malformation and treatment may persist in these patients, especially like urinary complications stream (one-fifth) and faecal incontinence (one-seventh), as seen in our series. A proper long-term follow-up is needed for the management of late complications.
