Augmentation cystoplasty in children with neuropathic bladder: long-term outcomes after 30 years experience.

Augmentation cystoplasty (AC) is a useful alternative for the treatment of neuropathic bladder, although there are few studies reporting long-term results. We assess our experience over the last 30-years. A retrospective study was conducted in patients with neuropathic bladder in whom AC was performed in our institution between 1990-2020. Demographic variables, pre- and post- AC urodynamic studies, long-term outcomes and postoperative complications were collected. Eighty-six patients (43 males and 43 females) underwent AC surgery with a median age of 12.8 years (interquartile range 9.6-15.1). Bladder augmentation was performed with ileum in 49 cases (57%), sigma in 32 cases (37.2%) and ureter in 5 cases (5.8%). In 27 patients an artificial urinary sphincter (AUS) was placed at the same intervention. The mean preoperative bladder capacity was 117 mL (SD 40), which was increased to 430 mL (SD 64) one year after surgery, this difference being statistically significant (P<0.001). Median follow-up was 24.5 years (interquartile range 17.5-26). Vesico-ureteral reflux improved after AC in 78.9% with no other surgical interventions. Seven mechanical complications associated with AUS were reported. Bladder lithiasis was reported in 9 patients. No bladder perforations were described. One patient developed bladder squamous cell carcinoma 16 years after AC, requiring radical cystectomy and Hautmann neobladder. Long-term results of this study demonstrate that AC is an effective surgical treatment in patients with neuropathic bladder patients without proper response to medical treatment. The risk of developing complications long after bladder augmentation makes close clinical follow-up of these patients essential.

058. A Rare Case: Anterior Wall Rectum Perforation Due to Intrauterine Device Migration

Background: Intrauterine devices (IUDs) are widely used for contraception due to their long-acting, safe, and effective nature in preventing pregnancy. However, common side effects and complications, such as vaginal bleeding, expulsion, displacement, translocation, and perforation necessitate attention, with translocation and perforation being rare but potentially severe, warranting prompt removal according to WHO recommendations. This study aims to document and analyze a rare case of rectal perforation resulting from the migration of an IUD. Case: A report was made from 31-year-old pregnant woman with a history of two cesarean sections presented with 10-day abdominal pain and an IUD inserted 42 days post-surgery, which MRI revealed had translocated into the left anterolateral rectal wall, prompting retroscopy for extraction. Uterine perforation and IUD migration into adjacent organs can result in various complications, including uterine, bladder, and intestinal perforation, with initial symptoms potentially being asymptomatic, emphasizing the need for routine check-ups. Retrieval of migrated IUDs can be achieved through methods such as endoscopy, laparoscopy, or laparotomy, as illustrated in a case involving a patient with abdominal pain and imaging evidence of IUD translocation to the rectum's anterior wall, managed through less invasive rectoscopy. Conclusion: Translocated IUDs may exhibit varying symptoms or none at all, necessitating removal regardless of type or location, with management guided by radiological and endoscopic findings alongside understanding abdominal organ anatomy

Atypical Emphysematous Cystitis Complicated by Asymptomatic Bladder Perforation

Atypical Emphysematous Cystitis Complicated by Asymptomatic Bladder Perforation

Cohort Profile: VZNKUL-NMIBC Quality Indicators Program: A Flemish Prospective Cohort to Evaluate the Quality Indicators in the Treatment of Non-Muscle-Invasive Bladder Cancer.

Purpose: Bladder cancer (BC) is a heterogeneous disease with varying outcomes, influenced by disease heterogeneity and variability in treatment and follow-up. Risk groups have been established for non-muscle-invasive BC (NMIBC) to standardize therapy, and several quality control indicators (QCIs) monitor adherence to these risk group-based guidelines. However, controversial results had been obtained regarding the oncological benefits of these QCIs until recent high-quality studies from large registries showed their usefulness. To improve adherence to the European Association of Urology (EAU) Guidelines and benchmark current care in Flemish hospitals within Vlaams Ziekenhuisnetwerk-KU Leuven (VZNKUL), a QCI program for NMIBC was initiated in 2013. This study aims to describe the demographic, clinical, and treatment data of patients enrolled in this program. Participants: The VZNKUL-NMIBC Quality Indicators Program Registry is a prospective cohort including patients treated and followed up with at seven academic and non-academic Flemish hospitals since June 2013. Data collection includes patient characteristics, tumor data, treatment, and oncological outcomes. Findings to date: From June 2013 to December 2020, 4744 transurethral resections of bladder tumors (TURBTs) from 2237 unique patients were analyzed. Most patients (80%) were men with a median age of 73. The median time from diagnosis to TURBT was 19 days. A single tumor was detected in 37% of TURBTs. Tumors larger than 3 cm were found in 20.8% of cases. In 46% of TURBTs, a reTURBT was scheduled according to guidelines. The complication rates were 7.5% and 2.4% for bladder perforation and bleeding, respectively. Postoperative single intravesical instillation of chemotherapy (SIVIC) was administered to 56.9% of 1533 indicated patients with a median time to administration of 4.7 h. Among the cohort, 60.4% had NMIBC, and 9.3% had muscle-invasive BC. Of 972 high-risk patients, 60.7% received adequate BCG induction, while 39.4% received adequate maintenance. After BCG induction ± maintenance, 39.7% were tumor-free, with 17.7% recurrence and 4% progression to muscle-invasive BC. BCG treatment was terminated early for 17% of patients due to intolerance. Early cystectomy was performed for 2.4% of the BCG-naïve patients, and 27.7% of patients with BCG failure underwent a BCG rechallenge. For intermediate-risk patients, 2.1% received adequate BCG, and 23% received intravesical chemotherapy. The median follow-up was 57 months. Five-year recurrence-free, progression-free, cancer-free, overall, and cancer-specific survival rates were 53%, 91.6%, 89%, 70.6%, and 95.6%, respectively, for the NMIBC patients. Of 400 non-metastatic MIBC patients, 217 (54.3%) underwent radical cystectomy (RC), of whom 46% received neoadjuvant chemotherapy, while 18 (4.5%) refused RC, and 74 (18.5%) were considered unfit for the surgery. Future plans: The VZNKUL-NMIBC Quality Indicators Program Registry will continue collecting data to evaluate QCIs and monitor treatment quality, enabling hospitals to benchmark their performance and improve patient care. Additionally, the registry's real-world data can support research and international collaboration. Trial registration: The study was registered on ClinicalTrials.gov (NCT04167332).

An international multicentre randomised controlled trial of en bloc resection of bladder tumour vs conventional transurethral resection of bladder tumour: first results of the en bloc resection of urothelium carcinoma of the bladder (EBRUC) II trial.

To determine the safety and oncological advantages of en bloc resection of bladder tumour (ERBT) vs conventional transurethral resection of bladder tumour (cTURBT) in terms of resection quality, staging quality, and safety. We conducted a single-blinded randomised controlled trial at seven European hospitals with the following inclusion criteria: first diagnosis of non-muscle-invasive bladder cancer, no singular carcinoma in situ, and tumour size >4.3 mm. Patients were randomised intraoperatively in a 1:1 ratio to either the ERBT or cTURBT group. Outcome analysis was performed using the chi-square test, t-test, and multivariate regression analysis. A total of 97 patients were randomised into the study (cTURBT = 40, ERBT = 57). A switch to cTURBT was necessary in two patients (3.5%) and 11.5% of the screened patients were preoperatively excluded for ERBT. There was no difference in the specimen presence of detrusor muscle with 73.7% in cTURBT and 67.3% in ERBT specimens (P = 0.69). There were no significant differences in mean operative time (ERBT 27.6 vs cTURBT 25.4 min, P = 0.450) or mean resection time (ERBT 16.3 vs cTURBT 15.5 min, P = 0.732). Overall the complication rate did not differ significantly (ERBT 18.2% vs cTURBT 7.5%, P = 0.142). Bladder perforations occurred significantly more often in the ERBT group (ERBT seven vs cTURBT none, P = 0.020). R0 status was reported more often after ERBT, whilst a second resection was significantly less frequent after ERBT (P = 0.018). Recurrence rates were comparable for both techniques after 6 months of follow-up. The feasibility of ERBT is higher than previously reported. Whereas other perioperative and safety parameters are comparable to cTURBT, bladder perforations occurred significantly more often in the ERBT group and raised safety concerns. This is why this trial was terminated.

Urogenital schistosomiasis, a leading cause of bladder squamous cell carcinoma

Abstract Introduction/Objective Schistosoma, genus of trematodes, commonly known as blood flukes are parasitic flatworms responsible for a group of infections in humans termed schistosomiasis and hundreds of millions of people are infected worldwide. In areas where Shistosoma is not endemic to the region most cases of bladder malignancy are of urothelial origin. In areas where Shistosoma is endemic bladder malignancy is more commonly squamous cell carcinoma. However, with increased travel, migration and tourism it is important to potentially consider Shistosoma infection in areas that are not typically considered endemic regions. Methods/Case Report A 62-year-old male presented to our hospital and revealed through an interpreter he has had 1.5 years hematuria with “pieces of meat or brown dirt”. Cystoscopy was performed and showed a large necrotic mass. CT scan showed an 8.2 cm exophytic bladder dome mass. TURBT was performed and a diagnosis of invasive high-grade urothelial carcinoma with squamous differentiation and with multiple Schistosoma organisms identified.The patient received Schistosoma treatment and was scheduled for radical cystectomy and ileal conduct. A few days before the scheduled procedure the patient presented to our emergency department with acute abdominal pain. He was subsequently diagnosed with progressive bladder cancer with new left malignant ureteral obstruction, which lead to hydronephrosis, DVT, abdominopelvic ascites and intraperitoneal bladder perforation. Abdominal fluid cytology showed atypical keratinizing squamous cells suspicous for malignancy and marked acute inflammation. Patient underwent cystectomy with ileal conduit and the specimen was sent to pathology for examination. Results (if a Case Study enter NA) NA Conclusion Gross examination showed an irregular perforated bladder. Microscopic examination showed a high grade urothelial carcinoma with squamous and sarcomatoid differentiation with detrusor muscle invasion. Additionally, Schistosoma organisms with a terminal spine and calcified eggs were identified. Some of the calcified egg material was engulfed by giant cells. The organisms are surrounded by a prominent eosinophilic infiltrate. Lymphovascular invasion is also noted. Schistosomiasis is associated with the development of squamous cell carcinoma of the bladder. It is important to maintain high oncological alertness for squamous cell carcinoma, particularly for patients arriving from endemic areas. Such as in our case, a patient from Somalia living in Kansas City.

The Role of Maximal TURBT in Muscle-Invasive Bladder Cancer: Balancing Benefits in Bladder Preservation and Beyond.

Radical cystectomy with lymph node dissection and urinary diversion is the gold-standard treatment for non-metastatic muscle-invasive bladder cancer (MIBC). However, in patients who refuse cystectomy, or in whom cystectomy carries a high risk, bladder-preserving therapies remain potential options. Bladder preservation therapies can include maximal debulking transurethral resection of bladder tumor (TURBT), concurrent chemoradiation therapy, followed by cystoscopy to assess response. At this time, maximal TURBT is recommended for patients prior to the initiation of chemoradiation therapy or in patients with residual bladder tumors after the completion of chemoradiation therapy. That being said, TURBT carries significant risks such as bladder perforation, bleeding, and infection, ultimately risking delayed systemic treatment. Hence, understanding its role within trimodal therapy is crucial to avoid undue suffering in patients. Herein, we review the current literature on the impact of debulking TURBT in non-metastatic MIBC.

Outcomes related to penile prosthesis reservoir removal: a 7-year multi-institutional experience.

The 3-piece inflatable penile prosthesis (IPP) is the most widely used device for erectile dysfunction refractory to medications, containing a reservoir inserted into the retropubic space (RPS) or an alternative/ectopic space (AES). Indications for removal of the reservoir include malfunction, malposition, or infection. In revision cases without infection, reservoir removal is sometimes optional. We reviewed outcomes and complications related to reservoir removal from a large multi-institutional series. We retrospectively reviewed databases at 6 institutions over 7years. Patients with artificial urethral sphincter, urethral sling, or mini-jupette were excluded. Outcomes and complications related to IPP reservoir removal were analyzed. Data were collected, but only reservoir-related complications at surgery were included. Data were compared between the RPS and AES cohorts to evaluate differences with a χ2 test, with significance at P < .05. Of 215 cases, there were 172 RPS and 43 AES reservoirs. The mean patient age was 65.3years. An overall 131 procedures were due to malfunction and 49 to malposition of an IPP component; 35 were secondary to infection. Among those retained (n = 44), reasons included reuse, avoiding surrounding structure damage, and difficult dissection. Among those removed (n = 171), 15 required a counterincision. To determine the statistical difference between those removed from the RPS and an AES, the χ2 test result was P = .00059, indicating a significant difference in the need for a counterincision between the groups. Complications included bladder perforation (n = 1) in the RPS group and an avulsion of the epigastric vessels requiring abdominal exploration (n = 1) in the AES group. To determine the statistical difference between RPS and AES complications, the χ2 test result was P = .365, indicating no significant difference between the groups. Strengths include being a multi-institutional study with high-volume skilled implanters. Limitations include being a retrospective review, with implanters exclusively performing penoscrotal incisions and not utilizing an infrapubic approach. Last, there was a lack of long-term follow-up with these patients. Removal of an IPP reservoir remains safe, with few intraoperative complications. Surgeons should be aware of the inferior epigastric vessels during removal in an AES or be willing to perform a counterincision to avoid injury to surrounding structures. Surgeons should also obtain preoperative imaging to identify the specific location of the reservoir and adjacent anatomy. This is the first multi-institutional study reviewing outcomes related to reservoir removal during IPP revision or removal surgery.

EP362 - Small Cell Ca of the Gall Bladder: A rare tumour of the gall bladder

Abstract Small cell carcinoma (SCC) of the gallbladder is an extremely rare tumour. Despite aggressive and varied treatments, its prognosis is poor. A 53/F presented with complaints of pain in abdomen and fever since 3 days. Patient was vitally stable and tenderness present over the epigastric, Right hypochondrium and Right lumbar region. Except leucocytosis, all labs were WNL. CECT Abdomen pelvis was suggestive of suspicious Gall bladder perforation with necrotic lymph nodes in the peri-pancreatic region. The patient was taken for exploratory laparotomy and a perforated gall bladder was seen intra op and cholecystectomy was performed. Histopathology findings were suggestive of small cell carcinoma - gall bladder and IHC markers (Synaptophysin, CD56, Ki67, EMA, CK19) sent for confirmatory findings were raised. Post op PET CT shows periportal, paracaval and aortocaval metastatic lymph nodes. Chemotherapy regimen (cisplatin + itoposide) was started post op and patient is under follow up. The incidence of SCC of the GB is approximately 0.5% of all GB cancers. Among NETs of the gastrointestinal tract, SCC of the GB compromises 0.2%. Less than 100 cases of this tumour have been documented in the English literature. Surgery is the mainstay of GB cancer treatment. Due to poor prognosis of SCC of the GB, even when curative surgery is possible, additional treatment methods such as chemoradiation should be considered.

En-bloc resection of non-muscle invasive urinary bladder tumors using low power Holmium laser-A new promise.

Urinary bladder tumors are one of the most common urological malignancies. Traditionally, it has been initially managed with conventional trans-urethral resection of urinary bladder tumors (cTURBT) which has certain drawbacks and complications. Efforts have been made to find newer methods for management. In this study, we have used low power Holmium laser en-bloc resection and have assessed its safety, efficacy and feasibility. Forty patients have been included in this prospective observational study who underwent low power Holmium laser en-bloc resection of urinary bladder tumor after taking Institutional ethical committee clearance and informed consent from all the patients. Intra-operative and post-operative data were collected. The average tumor size was 21.68 ± 9.55 mm. Out of those, 65% of the patients had a tumor less than 3 cm in size. Fourteen patients (35%) had tumors at multiple sites. The average duration of resection per tumor was 24.84 ± 6.83 min. None of the cases required conversion to cTURBT. There was no obturator reflex or urinary bladder perforation in any of the cases. Detrusor muscle was present in the histopathology reports of 92.5% patients. The average duration of catheterization was 1.82 ± 0.61 days. For NMIBC's, low power Holmium laser en-bloc resection is a safe procedure with minimum risk of complications. High rate of detrusor-positive specimens indicates its efficacy and feasibility.

Conservative treatment of intraperitoneal bladder perforations: a conscious choice or forced measure

Intraperitoneal traumatic perforations of the bladder of any origin (e.g., external trauma, iatrogenic injuries) and spontaneous ruptures are conditions that, according to the canons of surgery, require emergency surgical intervention by one or another access. However, some studies have indicated the possibility of conservative management of such patients — both adults and children. A review of publications describing the results of conservative treatment of patients with intraperitoneal bladder perforations was performed. Overall, 2,679 publications related to intraperitoneal perforations of the bladder were found in the available scientific databases, of which only 72 focused on issues of conservative treatment. In 13 of them, the possibility of such an approach is denied, but without reference to their own material. Analysis of the literature demonstrated that conservative management of intraperitoneal perforations of the may be feasible in certain circumstances, sometimes being a crucial measure. Indications for conservative treatment techniques include the absence of peritonitis, small perforation size, and short periods from the moment of perforation. However, all these indications are in the nature of opinions and assumptions and are not part of algorithmic tactics. The effectiveness of this approach remains unclear. The frequency of unsatisfactory outcomes ranges from 10% to 50%, which indicates the inappropriateness of conservative treatment. With the small number of studies and conflicting results obtained prohibits us to consider this technique as the method of choice for treating patients with intraperitoneal perforations of the bladder.

A comparative study of ultrasonography versus peripheral nerve stimulator-guided obturator nerve block for transurethral resection of bladder tumor under spinal anesthesia

Background: Transurethral resection of bladder tumor (TURBT) is usually done spinal anesthesia but it does not prevent the obturator reflex leading to bladder perforation, bleeding, or incompletely resection of resection of the tumor which could be prevented by obturator nerve block (ONB) in TURBT. Aims and Objectives: The aim of our study is to compare the effectiveness of ONB by peripheral nerve stimulator (PNS) and ultrasonography (USG) in TURBT and also compare morbidity between USG- and PNS-guided ONB in TURBT under spinal anesthesia. Materials and Methods: Sixty patients were randomly divided into two groups. Group (1) patients had a PNS-guided ONB and Group (2) patients had ONB-guided ONB. The presence or absence of adductor muscles reflexes was recorded. Bladder perforation and bleeding during surgery were also recorded. Results: A success rate of 90% was achieved in the Group (2) compared to 66% in Group (1) which was clinically significant with P=0.049. Complete bladder perforation was detected in four patients in Group (1) whereas no perforation was observed in Group (2). Bleeding was observed in both groups but severe bleeding was present in five patients in Group (1) and required a blood transfusion. Conclusion: We concluded that USG-guided ONB is more efficient and safer as compared to PNS-guided ONB.

Transvesical blockade of the obturator nerve to prevent adductor contraction in transurethral resection of urinary bladder tumor.

Urinary bladder tumors are one of the most common urological malignancies. Traditionally, it has been managed with trans-urethral resection of urinary bladder tumor (TURBT) for both diagnostic and therapeutic purposes. During TURBT of lateral wall tumors, there is risk of obturator nerve reflex (ONR), which can lead to serious complications such as inadvertent bleeding and urinary bladder perforation. To prevent this, obturator nerve block is given after spinal anesthesia. In this study, we have used the transvesical approach to block the obturator nerve. In total, 60 patients were included in the study. In 30 of them, TURBT was performed under only SA and transvesical obturator nerve block (ONB). In the other 30 patients, TURBT was performed under SA and peripheral nerve stimulator (PNS) guided obturator nerve block (performed by anesthetists) was given. The patients underwent TURBT using conventional monopolar cautery. The procedure time and peri-operative complications were studied. In all patients, informed consent was taken. In this study, 30 ONBs (all bilateral) were performed transvesically. After confirming the location of the obturator nerve, transvesical ONB was given using local anesthetic. Two patients (6.67%) experienced adductor jerk during the operation. In the 30 patients who underwent peripheral nerve stimulator (PNS) guided ONB, 6 of the patients (20%) experienced adductor jerk during the operation and 1 of those (3.33%) suffered from urinary bladder perforation which was managed conservatively. Transvesical ONB is an easy method to prevent adductor jerk during TURBT of lateral wall tumors. The learning curve is less and it has a high success rate.

Advancements in ectopic reservoir placement for inflatable penile prostheses.

Traditional reservoir placement (RP) into the space of Retzius during three-piece inflatable penile prosthesis implantation has been associated with serious bladder, iliac vessel, and bowel complications, encouraging the development of "ectopic" RP methods. In this study we sought to document an up-to-date, comprehensive analysis of ectopic RP techniques regarding both patient satisfaction and clinical complications. A PubMed, Ovid MEDLINE, and Cochrane Library literature search of English language articles from 1966 to 2023 with keywords "inflatable," "penile prosthesis," "reservoir," and "placement" gave 179 publications, 70 of which were included in a comprehensive chronology and investigation after review. Overall, 12 retrospective studies detailing 9 ectopic RP techniques were compared for discussion. Sufficient data for comparison were found for 9 ectopic RP methods: posterior/anterior to transversalis fascia (PTF/ATF); high submuscular (HSM); HSM "Five-Step" technique (HSM-FST); lateral retroperitoneal (LR); sub-external oblique (SEO); direct vision, transfascial (DVT); low submuscular with transfascial fixation (LSM w/ TFF); and midline submuscular reservoir (MSMR). Although rare, serious complications have occurred with the use of ectopic RP techniques: 2 bladder perforations on implantation with PTF RP, a delayed bowel obstruction with HSM RP, and a colonic injury in a patient with a history of colon surgery with LR RP. Generally, herniation is the most relevant clinical complication in ectopic RP. At the time of this review there was no reported herniation with LR, SEO, LSM w/ TFF, or MSMR, likely due to fixation steps and/or reinforced spaces. Regarding patient satisfaction, HSM, HSM-FST, and LSM w/ TFF had similarly high rates of patient satisfaction while other techniques had no patient satisfaction data available. Importantly, reservoir palpability/visibility relates directly to patient satisfaction. Levels of palpability and/or visibility were reported in patients who underwent PTF/ATF, HSM, HSM-FST, SEO, and LSM w/ TFF, whereas no palpability was reported in patients who underwent LR, DVT, and MSMR. Proper comparison of ectopic methods is not possible without standardized patient surveys, consistent complication reporting, and larger sample sizes, indicating the need for a large, prospective, multisurgeon trial.

Two management cases of intrauterine device translocation to the bladder

Introduction Intrauterine devices (IUDs) are widely used worldwide. One of the rare but serious complications is uterine perforation and the penetration of an IUD through the uterine wall into the bladder. In this report, we present two cases of IUD removal from the bladder wall.Clinical case. Two patients were referred for recurrent episodes of dysuria. Medical imaging and cystoscopy revealed a foreign body in the bladder wall, which was confirmed to be an IUD that had been inserted into the uterine cavity several years prior and partially migrated into the bladder lumen. Both patients underwent successful transurethral surgery, with complete removal of the IUD without fragmentation.Discussion. The removal of the IUD through the bladder did not cause any complications, and the patients were discharged from the hospital after five days. The translation of the IUD is possible if there is partial or complete damage to the wall of the cervix, isthmus or uteral body during the installation of the device.Conclusion. Patients with an IUD in place and frequent episodes of acute cystitis should have a cystoscopy to rule out bladder perforation caused by the IUD. The removal of the IUD through the urethra using an cystoscope and forceps is a relatively simple procedure that does not usually cause any intraoperative, immediate or delayed postoperative complications.

Assessment of Early Laparoscopic Cholecystectomy in Management of Acute Calcular Cholecystitis

Abstract Background Acute cholecystitis is one of the most significant diseases in the Western world and has a high socioeconomic impact. Mainly, patients with gallstones and older adults are affected. The main complication of acute cholecystitis is recurrent biliary colic and cholestasis. The latter may lead to ascending cholangitis, and while this can be managed with antibiotics, other complications cannot be cured conservatively such as gangrenous changes, gall bladder perforation and biliary leakage, and acute necrotic gallstone pancreatitis. Liver abscesses and underlying incidental carcinoma have also been reported in some cases. Aim of the Work The purpose of this study is to focus on success rate of early laparoscopic cholecystectomy as a management of acute calcular cholecystitis along with its operative and post- operative outcomes. Patients and Methods This is a prospective cohort study conducted on forty (40) patients presenting to Ain-Shams University hospitals and authorized hospitals presented with acute calcular cholecystitis starting from January 2021 and December 2021. Results Our study demonstrates that in terms of morbidity and mortality, early laparoscopic cholecystectomy is safe, feasible and cost-effective for cases of acute cholecystitis. The outcome of the patients in our study provides further evidence that early laparoscopic cholecystectomy can be performed within the first 72 hours of symptoms with no significant increase in length of operation. Moreover, there was no significant increase in the rate of major intra operative or post operative complications such as bleeding, bile duct injury, bowel injury, wound infection and conversion to open cholecystectomy. The major advantage of early cholecystectomy was that early laparoscopic cholecystectomy allows significantly shorter total hospital stay and reduction in days away from work. Moreover, it avoids repeated admissions for recurrent symptoms. Conclusion Early laparoscopic cholecystectomy is safe, feasible and cost-effective for cases of acute cholecystitis and its major advantage is that it allows significantly shorter total hospital stay and reduction in days away from work and avoids repeated admissions for recurrent symptoms.

Perioperative Outcomes and Trends in Transurethral Resection of Bladder Tumors with Photodynamic Diagnosis: Results from the GeRmAn Nationwide Inpatient Data Study.

Background: Photodynamic diagnosis (PDD) during transurethral resection of bladder tumor (TURBT) is guideline recommended, as it improves bladder cancer detection rates. However, the extent to which PDD is implemented in everyday clinical practice has not been thoroughly assessed. We aimed to evaluate the current trends and major perioperative outcomes of TURBT with PDD. Methods: The present study evaluated the GeRmAn Nationwide inpatient Data (GRAND) from 2010 (the year when PDD started to be coded separately in Germany) to 2021, which were made available from the Research Data Center of the German Bureau of Statistics. We undertook numerous patient-level and multivariable logistic regression analyses. Results: Overall, 972,208 TURBTs [228,207 (23%) with PDD and 744,001 (77%) with white light] were performed. Patients offered PDD during TURBT were younger (p < 0.001), presented fewer comorbidities (p < 0.001) and were discharged earlier from hospital (p < 0.001). PDD was associated with additional costs of about EUR 500 compared to white-light TURBT (p < 0.001). The yearly TURBT cases remained relatively stable from 2010 to 2021, whereas utilization of PDD underwent a 2-fold increase. After adjusting for major risk factors in the multivariate regression analysis, PDD was related to lower rates of transfusion (1.4% vs. 5.6%, OR: 0.29, 95% CI: 0.28 to 0.31, p < 0.001), intensive care unit admission (0.7% vs. 1.4%, OR: 0.56, 95% CI: 0.53 to 0.59, p < 0.001) and 30-day in-hospital mortality (0.1% vs. 0.7%, OR: 0.24, 95% CI: 0.22 to 0.27, p < 0.001) compared to white-light TURBT. On the contrary, PDD was related to clinically insignificant higher rates of bladder perforation (0.6% versus 0.5%, OR: 1.3, 95% CI: 1.2 to 1.4, p < 0.001), and reoperation (2.6% versus 2.3%, OR: 1.2, 95% CI: 1.1 to 1.2, p < 0.001). Conclusions: The utilization of PDD with TURBT is steadily increasing. Nevertheless, the road toward the establishment of PDD as the standard of care for TURBT is still long, despite of the advantages of PDD.
