Prevalence and morbidity of urogenital schistosomiasis among pre-school age children in Cubal, Angola.

Schistosomiasis is one of the most important neglected tropical diseases, with a great impact on public health and more than 200,000 deaths annually. Schistosoma haematobium causes urinary tract (UT) morbidity. Since schistosomiasis morbidity control programs focus on children older than 5 years, pre-school age children (PSAC) morbidity is not well known. We conducted a cross-sectional study in Cubal (Angola) among 245 PSAC with the objective of evaluating the prevalence of S. haematobium infection, the intensity of infection, and associated morbidity. For this purpose, urine filtration test followed by microscopic visualization and ultrasound examinations were performed. The estimated overall prevalence of urogenital schistosomiasis was 30.2% (CI 95%; 24.5-35.9), with 20.3% (CI 95%; 15.3-25.3) of the samples analysed showing a high intensity of infection. A total of 54.5% (CI 95%; 47.6-61.8) of infected children presented UT lesions, showing a significant association between schistosomiasis infection and UT morbidity (p-value < 0.001). Bladder wall thickening was the most common lesion, being present in 100% of abnormal ultrasounds. We found that anaemia and severe malnutrition were not significantly associated with the development of UT lesions. S. haematobium infection in PSAC causes great UT detectable morbidities. Therefore, there is an evident need of including them in mass drug administration (MDA) campaigns and consequently the development of an adapted praziquantel treatment dosage for children under 2 years of age.

Schistosoma haematobium infection and morbidity risk factors for pre-school age children in western Angola: A knowledge, attitudes and practices survey.

Urogenital schistosomiasis is one of the most prevalent parasitic diseases in sub-Saharan Africa. It is a poverty-related disease conditioned by behavioural practices. Our objective is to evaluate the awareness, mindset and habits about urogenital schistosomiasis in the community of Cubal (Angola), as well as its association with infection and urinary tract morbidity in pre-school age children. A cross-sectional study of knowledge, attitudes and practices at home was conducted between February and May 2022 with 250 participants. Overall, 93.6% of those surveyed had some prior knowledge about schistosomiasis and, among all the symptoms associated with this disease, blood in the urine was the best known (54.4%). Nevertheless, 57.6% obtained a medium knowledge score. Regarding attitude, the majority of respondents had a high attitude score (79.2%) with 96.0% willing to participate in mass drug administration campaigns. Laundry in the river was the most common risk practice (61.2%) and 55.2% out of the total were classified with a low practice score. Low knowledge about symptoms and transmission by caregivers was the outstanding risk factor for infection in pre-school age children (OR = 16.93, 95%CI: 3.93-72.82), and lack of knowledge that avoiding entering the river prevents schistosomiasis was the main risk factor for morbidity in PSAC (OR = 8.14, 95%CI: 1.14-58.25).

Urinary interleukins (IL)-6 and IL-10 in schoolchildren from an area with low prevalence of Schistosoma haematobium infections in coastal Kenya.

Urinary cytokines are gaining traction as tools for assessing morbidity in infectious and non-infectious inflammatory diseases of the urogenital tract. However, little is known about the potential of these cytokines in assessing morbidity due to S. haematobium infections. Factors that may influence the urinary cytokine levels as morbidity markers also remain unknown. Therefore the objective of the present study was to assess how urinary interleukins (IL-) 6 and 10 are associated with gender, age, S. haematobium infections, haematuria and urinary tract pathology and; 2) to assess the effects of urine storage temperatures on the cytokines. This was a cross-sectional study in 2018 involving 245 children aged 5-12 years from a S. haematobium endemic area of coastal Kenya. The children were examined for S. haematobium infections, urinary tract morbidity, haematuria and urinary cytokines (IL-6 and IL-10). Urine specimens were also stored at -20°C, 4°C or 25°C for 14 days before being assayed for IL6 and IL-10 using ELISA. The overall prevalence of S. haematobium infections, urinary tract pathology, haematuria, urinary IL-6 and urinary IL-10 were 36.3%, 35.8%, 14.8%, 59.4% and 80.5%, respectively. There were significant associations between prevalence of urinary IL-6, but not IL-10, and age, S. haematobium infection and haematuria (p = 0.045, 0.011 and 0.005, respectively) but not sex or ultrasound-detectable pathology. There were significant differences in IL-6 and IL-10 levels between urine specimens stored at -20°C and those stored at 4°C (p<0.001) and, between those stored at 4°C and those stored at 25°C (p<0.001). Urinary IL-6, but not IL-10, was associated with children's age, S. haematobium infections and haematuria. However, both urinary IL-6 and IL-10 were not associated with urinary tract morbidity. Both IL-6 and IL-10 were sensitive to urine storage temperatures.

Prevalence of Kidney and Urinary Tract Complications in Fabry Disease from 2000 to 2020: A Global Cohort Study Including 10,637 Patients.

Fabry disease, an X-linked lysosomal storage disorder, causes progressive globotriaosylceramide accumulation in cells throughout the body. Characteristic multiorgan manifestations include renal dysfunction (Fabry nephropathy) and associated urinary tract complications. Enzyme replacement therapy (ERT) has been available since 2001, but contemporary real-world data are lacking regarding Fabry nephropathy risks and treatment outcomes. This retrospective cohort study analyzed electronic medical records data for 10,637 Fabry disease patients from the TriNetX research database. Kidney and urinary tract outcomes were evaluated over two decades, 2000-2010 and 2011-2020. Outcomes assessed included chronic kidney disease (CKD), urinary tract infections, urinary incontinence, obstruction, renal insufficiency, and end-stage renal disease (ESRD). The prevalence of stage 4-5 CKD nearly doubled between 2000-2010 and 2011-2020, while ESRD prevalence rose over 4-fold. Incidence rates showed similar marked elevations across renal and urologic complications. Females and Black patients experienced disproportionate escalations in kidney and urinary tract morbidity. This large cohort study revealed significantly increased Fabry nephropathy and associated urologic complications over the past two decades, contradicting expectations of reduced morbidity with ERT availability. The findings highlight needs to optimize screening, treatment strategies, monitoring practices, and address disparities to curb rising disease burden and improve patient outcomes.

Knowledge, Attitudes and Practices on Urinary Schistosomiasis-Related Morbidity among Communities in Itilima District, Tanzania

Long-term infections by urinary schistosomiasis can result in urinary tract morbidities and increase the threats to public health. Information on the community’s knowledge, attitudes, and practices (KAP) on various aspects of urinary schistosomiasis, caused by Schistosoma haematobium has been lacking in Itilima District, which is likely to perpetuate the transmission of the disease and its negative health consequences. This study assessed knowledge, attitudes and practices on schistosomiasis-related morbidities in Itilima District from February to June 2021. A cross-sectional survey using a structured questionnaire was used, and a total of 657 participants were involved in the study. A total of 575 participants (87.5%) had awareness on schistosomiasis compared to 82 (12.5%) who were not aware of the disease, and this variation was statistically significant (x² = 369.938, DF = 1, p &lt; 0.001). The relationship between urinary schistosomiasis and its related morbidities was known by 111 (16.9%) respondents, while 546 (83.1%) knew nothing about it, and this variation was also statistically significant (c2 = 388.166, DF = 1, p &lt; 0.001). It can be concluded that knowledge of urinary schistosomiasis and its related morbidities among the communities was limited. This is possibly because knowledge of infection stages of S. haematobium that causes the morbidity requires an understanding of disease etiology. Therefore, this study recommends that interventions to impart knowledge on schistosomiasis and the associated morbidities should be implemented in Itilima District.&#x0D; Keywords: Schistosomiasis, Urinary tract morbidity, Knowledge, Attitudes and Practices, Itilima District

Postpartum urinary retention: what are the sequelae? A long-term study and review of the literature

Introduction and hypothesisPostpartum urinary retention (PUR) may cause long-term urogenital tract morbidity. The incidence ranges from 0.18 to 14.6%, but the importance of prompt diagnosis and appropriate management is often underappreciated. The paucity of data on long-term outcome after PUR contributes to these drawbacks. The aim of this study was to assess long-term persistence of elevated PVR (post-void residual urine) volume after PUR. Pathophysiology, risk factors and management of PUR are reviewed.MethodsIn our tertiary referral urogynecology unit in the University Women’s Hospital of Bern, Switzerland, all patients who were referred for PUR were asked to participate in this study. PVR was measured sonographically every 2 days until day 15, then after 6, 12, 24 and 36 months and, if increased, the patients were instructed to perform clean intermittent self-catheterization. If retention persisted longer than the lactation period, multichannel urodynamics was performed.ResultsSixty-two patients were included. The median PVR normalized at day 7. Long-term voiding disorders were found in 8.2%, 6.7%, and 4.9% after 1, 2, and 3 years respectively. Multichannel urodynamics confirmed in all patients with persisting retention an acontractile detrusor and de novo stress urinary incontinence in 4 cases. Quantile regression did not reveal any factor contributing to earlier recovery. Eighty-nine percent of the patients with PUR had operative vaginal deliveries, emphasizing the importance of this risk factor for PUR.ConclusionsIn most cases PUR resolves early, but voiding difficulties persist more often than previously thought, and for these patients the consequences are devastating. Obstetric awareness, early active management, and developing management strategies in the postpartum period might preclude lower urinary tract morbidity.

Focused Assessment with Sonography for Urinary Schistosomiasis (FASUS)-pilot evaluation of a simple point-of-care ultrasound protocol and short training program for detecting urinary tract morbidity in highly endemic settings.

Urogenital schistosomiasis (UGS) causes inflammation and fibrosis of the urinary tract. In resource-limited settings, affordable tools for morbidity assessment in clinical care are needed. Point-of-care ultrasound has not yet been validated for UGS-related pathology. We developed a protocol for Focused Assessment with Sonography for Urinary Schistosomiasis (FASUS), assessing pathology of the bladder wall, ureters and kidneys. Following standardized training, two clinicians performed FASUS on children and adults with hematuria in Lambaréné, Gabon. Recorded ultrasound clips were remotely reviewed by two ultrasound experts as a diagnostic reference. In 2015 and 2016, scans were performed in 118 patients. The image quality was sufficient in 90% of bladder views and more than 97% of kidney views. UGS-compatible pathology was detected in 51/118 (43%) by the operator and in 46/107 (43%) by the experts among baseline scans of sufficient quality. Inter-rater agreement between operators and experts was very good (κ>0.8) for hydronephrosis and good (κ>0.6) for bladder wall thickening. FASUS is a promising clinical, point-of-care tool for detecting UGS-related urinary tract morbidity in symptomatic patients. Based on larger validation studies, appropriate diagnostic and therapeutic algorithms for the use of FASUS should be established.

Urinary tract morbidity after nerve-sparing radical hysterectomy in women with cervical cancer

Nerve-sparing radical hysterectomy (NSRH) has been developed as a method of cervical cancer treatment to reduce surgical morbidity compared with radical abdominal hysterectomy. The aim of this study was to analyze the short- and long-term effects of NSRH on urinary tract function. A study group of 117 patients underwent NSRH type C1 with pelvic lymphadenectomy for cervical cancer stages IB1-IB2 without adjuvant radiotherapy at our department. A total of 106 patients aged 21-74years (mean age 44.8) were available for follow-up at 1year after surgery. A transurethral catheter was left in place for 48h after surgery, and the postvoid residual (PVR) volume was measured after its removal. One week before surgery and 12months after NSRH, lower urinary tract function was evaluated by an urodynamic examination. Five days after surgery, the PVR volume was greater than 100ml in 5 patients (4.7%) and a suprapubic catheter was inserted into these women for bladder training over the following days. Within 14days after surgery, urination without PVR was achieved in all women who underwent surgery. Postoperatively, a slight increase in the average maximum bladder cystometric capacity was recorded from 420 to 445ml (p value 0.009) without prolonging the voiding time. Other urodynamic parameters were not significantly different before and 12months after NSRH. In this series, NSRH preserved voiding function and bladder sensation at 1year and did not appear to compromise oncological outcome.

Inflammation dynamics after praziquantel treatment of Schistosoma haematobium reflected by urinary eosinophil cationic protein.

This cohort study assessed urinary eosinophil cationic protein (ECP) as an indicator for urinary tract morbidity and inflammation indication related to single-dose or dual-dose praziquantel (PZQ) treatment. Urinary ECP was measured at baseline, 24 h and 9 weeks after treatment (baseline 305, follow-up 204 participants, ages 2-40 years). ECP was significantly associated with the intensity of infection at baseline (p<0.05). Levels at baseline were 8.31 times higher (p<0.01) in participants with bladder morbidity than in those without. There was no correlation with kidney morbidity and no significant effect of a repeated dose of PZQ 40 mg/kg. Baseline ECP and ECP after 9 weeks were associated with microhaematuria (geometric mean ratio at baseline 7.56 [95% confidence limit {CL} 2.34-24.45]; p<0.01) and macrohaematuria (geometric mean ratio at baseline 6.22 [95% CL 2.71-14.24]; p<0.001). Mean levels of ECP dropped significantly during the first follow-up period and far less so in the second follow-up period (mean ECP at baseline: 70.8 ng/mL; ECP at 24 h: 24.5 ng/mL; ECP at 9 weeks: 14.6 ng/mL). The urine ECP decrease happened immediately after treatment, reflecting the rapid action of PZQ on eggs in the bladder tissue. ECP in urine can be used as an indirect marker of the degree of local inflammatory reaction in the bladder and is not significantly affected by a repeated dose of PZQ.

Ultrasonographic evaluation of urinary tract morbidity in school-aged and preschool-aged children infected with Schistosoma haematobium and its evolution after praziquantel treatment: A randomized controlled trial

BackgroundSchistosoma haematobium infections are responsible for significant urinary tract (UT) complications. Schistosomiasis control programs aim to reduce morbidity, yet the extent of morbidity in preschool-aged children and the impact of treatment on morbidity reduction are not well studied.MethodologyOur study was embedded in a randomized, placebo-controlled, single-blind trial in Côte d’Ivoire, which evaluated the efficacy and safety of three doses (20, 40 and 60 mg/kg) of praziquantel in school-aged (SAC) and preschool-aged (PSAC) children infected with S. haematobium. Enrolled children were invited to participate in an ultrasound examination prior and six months after treatment. At these time points 3 urine samples were collected for parasitological and clinical examinations.Principal findings162 PSAC and 141 SAC participated in the ultrasound examination at baseline, of which 128 PSAC and 122 SAC were present at follow-up. At baseline 43% (70/162) of PSAC had UT morbidity, mostly at bladder level and 7% had hydronephrosis. 67% (94/141) of SAC revealed mainly moderate UT pathology, 4% presented pseudopolyps on the bladder wall, and 6% had pyelectasis. At follow up, 45% of PSAC and 58% of SAC were S. haematobium positive, mostly harboring light infection intensities (41% and 51%, respectively). Microhematuria was present in 33% of PSAC and 42% of SAC and leukocyturia in 53% and 40% of PSAC and SAC, respectively. 50% (64/128) of PSAC and 58% (71/122) of SAC presented urinary tract morbidity, which was mainly mild. A significant correlation (p<0.05) was observed between praziquantel treatment and reversal of S. haematobium induced morbidity. Progression of UT pathology decreased with increasing praziquantel dosages. A worsening of morbidity was observed among children in the placebo group.Conclusion/SignificanceBladder morbidity is widespread among PSAC. Praziquantel treatment is significantly associated with the reversal of S. haematobium induced morbidity, which underscores the importance of preventive chemotherapy programs. These programs should be expanded to PSAC to prevent or decrease the prevalence of morbidity in young children. This trial is registered as an International Standard Randomized Controlled Trial, number ISRCTN15280205.

Schistosoma haematobium and soil-transmitted Helminths in Tana Delta District of Kenya: infection and morbidity patterns in primary schoolchildren from two isolated villages.

BackgroundSchistosomes and soil-transmitted helminths (STH) (hookworm, Trichuris trichiura and Ascaris lumbricoides) are widely distributed in developing countries where they infect over 230 million and 1.5 billion people, respectively. The parasites are frequently co-endemic and many individuals are co-infected with two or more of the species, but information on how the parasites interact in co-infected individuals is scarce. The present study assessed Schistosoma haematobium and STH infection and morbidity patterns among school children in a hyper-endemic focus in the Tana River delta of coastal Kenya.MethodsTwo hundred and sixty-two children aged 5–12 years from two primary schools were enrolled in the study. For each child, urine was examined for S. haematobium eggs and haematuria, stool was examined for STH eggs, peripheral blood was examined for eosinophilia and haemoglobin level, the urinary tract was ultrasound-examined for S. haematobium-related pathology, and the height and weight was measured and used to calculate the body mass index (BMI).ResultsPrevalences of S. haematobium, hookworm, T. trichiura and A. lumbricoides infection were 94, 81, 88 and 46 %, respectively. There was no significant association between S. haematobium and STH infection but intensity of hookworm infection significantly increased with that of T. trichiura. Lower BMI scores were associated with high intensity of S. haematobium (difference =−0.48, p > 0.05) and A. lumbricoides (difference =−0.67, p < 0.05). Haematuria (both macro and micro) was common and associated with S. haematobium infection, while anaemia was associated with high intensity of S. haematobium (OR = 2.08, p < 0.05) and high hookworm infections OR = 4.75; p < 0.001). The majority of children had eosinophilia, which was significantly associated with high intensity of hookworm infection (OR = 5.34, p < 0.05). Overall 38 % of the children had ultrasound-detectable urinary tract morbidity, which was associated with high intensity of S. haematobium infection (OR = 3.13, p < 0.05).ConclusionPrevalences of S. haematobium and STH infections among the primary school children were high and the parasites were responsible for significant morbidity. A clear synergistic interaction was observed between hookworm and T. trichiura infections. Increased coverage in administration of praziquantel and albendazole in the area is recommended to control morbidity due to these infections.

Case-Control Study of Posttreatment Regression of Urinary Tract Morbidity Among Adults in Schistosoma haematobium-Endemic Communities in Kwale County, Kenya.

Previous population-based studies have examined treatment impact on Schistosoma-associated urinary tract disease among children, but much less is known about longer-term treatment benefits for affected adult populations in areas where risk of recurrent infection is high. In communities in Msambweni, along the Kenya coast, we identified, using a portable ultrasound, 77 adults (aged 17-85) with moderate-to-severe obstructive uropathy or bladder disease due to Schistosoma haematobium. Treatment response was assessed by repeat ultrasound 1-2 years after praziquantel (PZQ) therapy and compared with interval changes among age- and sex-matched infected/treated control subjects who did not have urinary tract abnormalities at the time of initial examination. Of the 77 affected adults, 62 (81%) had improvement in bladder and/or kidney scores after treatment, 14 (18%) had no change, and one (1.3%) had progression of disease. Of the 77 controls, 75 (97%) remained disease free by ultrasound, while two (3%) had apparent progression with abnormal findings on follow-up examination. We conclude that PZQ therapy for S. haematobium is effective in significantly reducing urinary tract morbidity from urogenital schistosomiasis among adult age groups, and affected adults stand to benefit from inclusion in mass treatment campaigns.

Schistosomiasis in pre-school-age children and their mothers in Chikhwawa district, Malawi with notes on characterization of schistosomes and snails.

BackgroundTo complement ongoing schistosomiasis control within national control programmes (NCPs) that administer praziquantel to school-age children, assessing the risk and extent of schistosomiasis in pre-school-age children (PSAC) is important.MethodsIn June 2012, schistosomiasis in Chikhwawa district, Malawi was assessed across 12 villages examining pre-school-age children (PSAC) and their mothers by serological and parasitological diagnosis, as supplemented with urine-antigen and questionnaire-interview methods. Urinary tract morbidity was inferred by haematuria and albuminuria assays.ResultsIn total, 49.5% (CI95 42.6-56.4) of 208 PSAC and 94.5% (CI95 90.9-98.1) of 165 mothers were seropositive for schistosomiasis, in 2 villages seroprevalence exceeded 75% in PSAC. Egg-patent urogenital and intestinal schistosomiasis was observed; 17.7% (CI95 12.4-23.2) of PSAC and 45.1% (CI95 37.4-52.8) of mothers having active schistosomiasis by parasitological and urine-antigen testing combined. PSAC often had extensive daily water contact and many (~25%) had haematuria and albuminuria. As eggs with an atypical morphology of Schistosoma haematobium were observed, a general selection of schistosome eggs was characterized by DNA barcoding, finding Group I S. haematobium and Group IV and V S. mansoni. Malacological surveys encountered several populations of Bulinus globosus but failed to find Biomphalaria.ConclusionsBoth PSAC and their mothers appear to be at significant risk of schistosomiasis and should be considered for treatment within the NCP of Malawi.

Micro-geographical heterogeneity in Schistosoma mansoni and S. haematobium infection and morbidity in a co-endemic community in northern Senegal.

Background Schistosoma mansoni and S. haematobium are co-endemic in many areas in Africa. Yet, little is known about the micro-geographical distribution of these two infections or associated disease within such foci. Such knowledge could give important insights into the drivers of infection and disease and as such better tailor schistosomiasis control and elimination efforts.MethodologyIn a co-endemic farming community in northern Senegal (346 children (0–19 y) and 253 adults (20–85 y); n = 599 in total), we studied the spatial distribution of S. mansoni and S. haematobium single and mixed infections (by microscopy), S. mansoni-specific hepatic fibrosis, S. haematobium-specific urinary tract morbidity (by ultrasound) and water contact behavior (by questionnaire). The Kulldorff's scan statistic was used to detect spatial clusters of infection and morbidity, adjusted for the spatial distribution of gender and age.Principal Findings Schistosoma mansoni and S. haematobium infection densities clustered in different sections of the community (p = 0.002 and p = 0.023, respectively), possibly related to heterogeneities in the use of different water contact sites. While the distribution of urinary tract morbidity was homogeneous, a strong geospatial cluster was found for severe hepatic fibrosis (p = 0.001). Particularly those people living adjacent to the most frequently used water contact site were more at risk for more advanced morbidity (RR = 6.3; p = 0.043).Conclusions/Significance Schistosoma infection and associated disease showed important micro-geographical heterogeneities with divergent patterns for S. mansoni and S. haematobium in this Senegalese community. Further in depth investigations are needed to confirm and explain our observations. The present study indicates that local geospatial patterns should be taken into account in both research and control of schistosomiasis. The observed extreme focality of schistosomiasis even at community level, suggests that current strategies may not suffice to move from morbidity control to elimination of schistosomiasis, and calls for less uniform measures at a finer scale.

Is there a relation between the radiation dose to the different sub-segments of the lower urinary tract and urinary morbidity after brachytherapy of the prostate with I-125 seeds?

Background and PurposeTo investigate possible relationships between the dose to the sub-segments of the lower urinary tract and lower urinary tract symptoms (LUTS) after brachytherapy of the prostate. Materials and MethodsThis study involved 225 patients treated for prostate cancer with I-125 seeds. Post-implant dose-volume histograms of the prostate, urethra, bladder wall, bladder neck and external sphincter were determined. Endpoints were the mean and the maximum International Prostate Symptom Score (IPSS) during the first 3months after the treatment. For binary analysis the patients were stratified in a group with enhanced LUTS and a group with non-enhanced LUTS. ResultsThe dose to 0.5cm3 of the bladder neck ‘D0.5cc-blne’ (p=0.002 and p=0.005), the prostate volume prior to treatment ‘Vpr-0’ (p=0.005 and p=0.024) and the pre-treatment IPSS (both p<0.001) were independently correlated with mean and maximum IPSS, respectively. Of the patients with a D0.5cc-blne⩾175Gy and a Vpr-0⩾42cm3, 68% suffered from enhanced LUTS, against just 30% of the other patients (p<0.0001). ConclusionsPre-treatment IPSS, prostate volume and dose to the bladder neck are correlated with post-implant IPSS. A combination of a large prostate and a high dose to the bladder neck is highly predictive for enhanced early LUTS.

Intravesical Ligation as a New Technique to Manage a Refluxing Native Ureter Without Simultaneous Nephrectomy in Renal Transplantation

BackgroundThis article aims to describe an original technique to correct refluxing native ureters observed during a prerenal transplantation study. The correction is performed by intravesical ligation of the native refluxing ureters at the same time as renal transplantation without simultaneous nephrectomy. MethodsBetween January 2004 and December 2010 we performed intravesical ligation of a refluxing ureter simultaneous with a transplantation procedure without a concomittant native nephrectomy in 12 of 345 subjects (3.47%). The 8 bilateral and 4 unilateral ligations were performed on 11 cadaveric and 1 living-related nonidentical donor transplantations. The implantation of the kidney donor ureter was performed anatomically in the bladder trigone through a transvesical ureteroneocystostomy with a transmural, submucosal antireflux tunnel. ResultsEarly and late postoperative recovery was satisfactory in all patients. There was no documented kidney area pain, proven urinary tract infection, morbidity or mortality attributed to the procedure. ConclusionsIntravesical ligation is a practical technique to manage vesicoureteral reflux into the native ureters simultaneously with the ureteral implantation of the kidney donor in a single surgical renal transplant procedure without native kidney nephrectomy.

Laparoscopic Radical Hysterectomy after Preoperative Brachytherapy for Stage IB1 Cervical Cancer: Feasibility, Results, and Surgical Implications in a Large Bicentric Study of 162 Consecutive Cases

To examine the feasibility and to report the results of laparoscopic radical hysterectomy (LRH) after initial uterovaginal brachytherapy (BT) for stage IB1 cervical cancer. We retrospectively reviewed patients at 2 comprehensive cancer centers who underwent initial BT followed 6-8 weeks later by LRH and lymph node dissection. Between 2003 and 2010, a total of 162 patients underwent LRH. The procedure was feasible via this approach in 160 cases (98.8%) (2 conversions to laparotomy). Eight perioperative complications occurred. Nineteen patients had nodal involvement. Peri- or postoperative ureteral morbidity occurred in 10 patients (6%). Twenty-four patients (15%) experienced postoperative dysuria. Histologically, only 9 patients had residual cervical disease ≥5 mm, and only 1 patient had parametrial lymphovascular space involvement (associated with nodal spread). No patient had vaginal disease or involved surgical margins. After a median follow-up of 39 (range 3-118) months, 9 patients experienced relapse. Five-year overall survival was 95% (range 88.2-97.9%). Radical hysterectomy using a laparoscopic approach is feasible and reproducible after initial BT for stage IB1 cervical cancer and is associated with excellent survival. Morbidity is close to that reported in patients treated with up-front surgery. In this large series, the morbidity associated with parametrial dissection and the fact that parametrial spread was observed in only 0.6% of the patients suggest that a simple extrafascial hysterectomy is perhaps sufficient in this context; the rate of urinary tract morbidity would then be reduced.

A Modification to Augmentation Cystoplasty With Catheterizable Stoma for Neurogenic Patients: Technique and Long-term Results

To evaluate the use of a modified Indiana continent urinary reservoir, the Indiana augmentation cystoplasty (IAC), for patients with neurogenic bladder (NGB). NGB with incontinence can be devastating for patients with neurologic illness. Augmentation cystoplasty with a continent catheterizable stoma creates a continent, low-pressure storage system, with catheterizable cutaneous stoma, leading to decreased urinary tract morbidity and increased quality of life. Retrospective chart review of the IAC procedure in a single center from 1993 to 2010 was performed and included subjects with NGB and minimum 1-year follow up. Patients' demographics, NGB diagnosis, surgery details, urodynamic findings, concurrent operations, complications, and continence outcomes were recorded. Thirty-four patients met the inclusion criteria. Mean age at time of surgery was 39.8 years. Neurologic diagnoses included multiple sclerosis (n = 12), spina bifida (n = 9), and spinal cord injury (n = 14). Concurrent surgeries included: bladder neck closure (n = 3), pubovaginal sling (n = 4), hysterectomy (n = 3), artificial urinary sphincter (n = 1), and cystolithotomy (n = 1). Mean estimated blood loss was 461.8 mL. Short-term postoperative complications were prolonged ileus (n = 2), wound infection (n = 1), and transfusion (n = 1). Median follow-up was 31 months. Long-term complications occurred in 15 (44.1%) patients: recurrent urinary tract infections (n = 4), pyelonephritis (n = 1), pelvic abscess (n = 1), seroma (n = 1), bladder stones (n = 2), and stomal revision in (n = 4). All patients were continent at latest follow-up. This modification of the Indiana continent urinary reservoir is an excellent surgical option providing a low-pressure reservoir with a reliable continence mechanism and easily catheterizable stoma, with few complications or need for reoperation.

Editorial Comment

This paper very nicely reviews the authors' experience with the Indiana augmentation cystoplasty (IAC) for patients with neurogenic bladder (NGB). Thirty-four patients underwent reconstruction, all of whom were unable to self-catheterize per their native urethra for a variety of reasons. In addition, 6 patients underwent a concomitant procedure (bladder neck closure, sling or artificial urinary sphincter [AUS]) to address an incompetent outlet. There are a variety of techniques (eg, Mitrofanoff, Monti, and T-limb) to construct a continent urinary stoma. There is no “best option” and surgeons should choose the technique with which they are most comfortable. The authors' comfort with this technique is evident, with a very acceptable rate of stoma revision and outstanding continence. A Modification to Augmentation Cystoplasty With Catheterizable Stoma for Neurogenic Patients: Technique and Long-term ResultsUrologyVol. 80Issue 2PreviewTo evaluate the use of a modified Indiana continent urinary reservoir, the Indiana augmentation cystoplasty (IAC), for patients with neurogenic bladder (NGB). NGB with incontinence can be devastating for patients with neurologic illness. Augmentation cystoplasty with a continent catheterizable stoma creates a continent, low-pressure storage system, with catheterizable cutaneous stoma, leading to decreased urinary tract morbidity and increased quality of life.
