[The mediating effects of self-efficacy between symptom experience and quality of life in prostatic hyperplasia patients after cystostomy].

OBJECTIVE: To evaluate the symptom experience of patients with benign prostatic hyperplasia and bladder fistula. Exploring the mediating effect of self-efficacy on the relationship between symptom experience and quality of life in patients with benign prostatic hyperplasia undergoing long-term indwelling cystostomy. METHODS: This study used a cross-sectional survey design. Patients with prostatic hyperplasia with cystostomy in the Urology department of General Hospital of Eastern Theater Command from January 2020 to February 2023 were selected, and relevant data were collected by IPSS, IIEF-5, HAMD, GSES, and quality of life score scale for statistical analysis. We then construct a structural equation model to evaluate the mediating effect of self-efficacy between symptom experience and quality of life. RESULTS: The average score of IPSS was (22.55±8.26) ; the average score of IIEF-5 was (10.54±4.10) ; the average score of HAMD was (6.82±2.35) ; the average score of self-efficacy was (20.80±8.65) ; and the average score of quality of life was (71.65±12.55) . Symptom experience was significantly negatively correlated with self-efficacy and quality of life( r=－0.496 , P<0.01；r=－0.518 , P<0.01) . Self-efficacy was significantly positively correlated with quality of life( r= 0.412，P<0.05). Symptom experience significantly negatively affected quality of life through self-efficacy (Effect = －0.218，P = 0.014) . CONCLUSION: Self-efficacy is positively correlated with the quality of life of patients with benign prostatic hyperplasia who have long-term indwelling cystostomy tube. Nursing staff can improve the level of self-efficacy of patients by implementing corresponding interventions.

Suprapubic catheterisation: a study of 1000 elective procedures.

OBJECTIVES: To investigate the risks and long-term outcomes of suprapubic catheter (SPC) insertion in a population predominantly with spinal cord injury. MATERIALS AND METHODS: We used the theatre database at the National Spinal Injuries Centre in Stoke Mandeville Hospital to identify 1000 consecutive SPC insertions from 1998 to 2015. We retrospectively analysed all records for these patients. RESULTS: Follow-up ranged from 4 weeks to 16.45 years (median 3.3 years). Either cystoscopy-guided suprapubic puncture (Lawrence Add-a-Cath trochar) or a direct incision onto a urethral sound (Lowsley retractor) followed by cystoscopy was used for 98% of insertions. Complications graded as Clavien-Dindo IIIb or higher occurred in 0.6% of patients. Return to theatre was necessary in 0.4%, including three laparotomies due to bleeding or misplacement of the catheter, but no bowel injuries occurred. One death occurred within 30 days due to pulmonary embolism. There were no significant differences in outcomes between insertion methods. Tolerance of long-term suprapubic catheterisation was high, despite 59% of cases experiencing mostly minor complications. Tract losses during routine community change and variability in antibiotic prescribing highlighted areas for educational development which could improve patient outcomes. CONCLUSIONS: This study supports the view that the risk of major complications from SPC insertion is lower than previously reported. Minor complications related to the catheter are common in the long term but are generally well tolerated.

Bladder preserving robotic pelvic exenteration for locally advanced rectal cancer-technique and short-term outcomes.

AIM: In selected patients with advanced rectal cancers involving the prostate or seminal vesicles, the bladder can be preserved to avoid the complications associated with an ileal conduit. The study was aimed at reviewing the technique and short-term outcomes of patients that underwent bladder sparing robotic pelvic exenteration with suprapubic cystostomy (SPC). METHODS: Case series of bladder preserving exenteration from a single tertiary care center. Technique for en-bloc prostatectomy with abdominoperineal resection is described. RESULTS: Five patients underwent bladder sparing robotic pelvic exenteration with SPC, all had R0 resections. Four patients had prostatic invasion and one patient had prostatic adenocarcinoma. Postoperative complications were seen in three patients of which two were re-explored. At a median follow-up of 10 months, two patients developed systemic relapses. There were no local recurrences. CONCLUSION: Robotic bladder sparing exenteration is technically feasible, provides acceptable short-term outcomes, and avoids complications of ileal conduit.

Preservation of native sigmoid colon for secondary continent cystostomy after multivisceral transplantation for chronic intestinal pseudo-obstruction.

Chronic intestinal pseudo-obstruction (CIPO) is characterized by severe digestive +/- urinary dysmotility. If the conservative management fails, multivisceral transplantation (MVT) may be needed. However, urinary dysmotility remains after MVT and requires to continue urinary catheterizations and/or drainage. We report on a boy with severe CIPO complicated by (1) chronic intestinal obstruction requiring total parenteral nutrition, decompression gastrostomy, and ileostomy; (2) recurrent line infections; (3) hepatic fibrosis; and (4) distension of the bladder and upper urinary tract, and recurrent urinary infections, leading to non-continent cystostomy for urinary drainage. He underwent MVT at the age of 5 years. The transplant included the liver, stomach, duodenum and pancreas, small bowel, and right colon. The distal native sigmoid colon was preserved. Fifteen months later, he underwent a pull through of the transplanted right colon (Duhamel's procedure), together with a tube continent cystostomy (Monti's procedure) using the native sigmoid. Postoperative course was uneventful, and the remaining ileostomy was closed 3 months later. Five years post-transplant, he is alive and well. He is fed by mouth with complementary gastrostomy feeding at night. He has 3-6 stools per day, with occasional soiling. The cystostomy is used for intermittent urinary catheterization 4 times/day and continuous drainage at night. He is dry, with rare afebrile urinary infections, normal renal function, and un-dilated upper urinary tract. Conclusion: in severe CIPO with urinary involvement, preservation of the distal native sigmoid colon during MVT allows secondary creation of a continent tube cystostomy, which is useful to manage persistent urinary disease.

How We Made Exstrophy Bladder Continent and Preserved the Renal Functions.

Purpose: Crucial requirement of exstrophy bladder repair is to make patients continent as well as to preserve kidney functions. We analyzed our patients' data retrospectively to study their continence and to find out the justification behind continence and preservation of renal functions. Patients and Methods: We selected files of 18 fully continent patients from 52 patients operated. Eleven out of 18 patients were presented from beginning and 7 were referred after around 8 to 14 years, as incontinent bladder following good repair of bladder neck and posterior urethra. Eleven were operated with complete primary repair of exstrophy along with pubic osteotomy minimal and were kept on cystostomy track (CT) till augmentation to vent out vesical pressure. In seven patients, we did reduction of caliber of posterior urethra and bladder neck along with CT followed by augmentation after 6 months. Results: All 18 patients are maintaining dry period for 24 h. Two patients had enuresis but are manageable with partial fluid restriction from evening. Seventeen out of 18 patients are maintaining their renal functions. Conclusion: No tension abdominal wall closure with rectus muscle apposition is essential to preserve repaired bladder exstrophy. Osteotomy prevents lateral drag to overcome failure of whole reconstruction. Increased "systolic" vesical pressure from contraction of small bladder might destroy the mechanism of continence and renal functions. Hence, venting of vesical pressure through CT is obligatory till augmentation which is of necessity to be done as early as possible to create a low-pressure continent system.

[Isolated continent urinary diversion: An interesting or often regretted indication?] / Cystostomie continente isolée : une indication intéressante ou que l'on regrette souvent ?

INTRODUCTION: The aim of this study is to evaluate the percentage of patients developing vesical overactivity after the realization of a continent stoma without bladder enlargement. MATERIAL AND METHOD: This is a retrospective monocentric study between January 2007 and April 2021. Patients undergoing an isolated continent urinary diversion for neurological or non-neurological reasons were included. The data collected concerned the clinical symptoms of bladder overactivity and their treatment as well as the pre- and postoperative urodynamic information. RESULTS: During the period, 9 patients were included. The main indications for continent urinary diversion were patients with spinal cord injury. Clinical bladder overactivity was found postoperatively in 78% (7) of the patients, and detrusor overactivity in 57% (4) of them. The main symptoms were urinary incontinence (67%) and pollakiuria (56%, 5 patients). Most of the patients benefited from associated treatments (78% pre- and postoperative), mainly anticholinergic drugs. No patient required botulinum toxin injections preoperatively, compared with 6 (67%) postoperatively. The time of initiation of these injections varied between 3 and 8 months postoperatively. CONCLUSION: Isolated continent urinary diversion seems to induce or increase bladder overactivity. A larger multicentric study is necessary to validate our hypothesis.

[Neurogenic bladder and continent cystostomy: Results of a monocentric cohort in a French university hospital]. / Vessies neurologiques et cystostomie continente : résultats d'une cohorte monocentrique dans un centre hospitalier français.

OBJECTIVE: The main objective was to evaluate the complications of continuous urinary shunts in a French university hospital according to surgical technique and functional results especially on continence. The secondary objective was to evaluate the management of complications. METHODS: A retrospective study was conducted between January 2008 and August 2017. Patients who had a continent cystostomy with or without bladder augmentation were included. Diversions for non-neurological causes were excluded. Cystostomy was performed using the appendix or a Monti's artifice. Data collected included complications and their management, functionality of the diversion and of the bladder reservoir, cystostomy continence, and urethral continence. RESULTS: Nineteen patients were included. The median follow-up time was 46 months. The majority of early postoperative complications were classified as grade II Clavien-Dindo. No postoperative deaths occurred. Late complications most frequently involved cystostomy duct stenosis (n=5), cystostomy incontinence (n=5), and urethral incontinence (n=8). Thirteen patients had revision surgery for late complications. Late complications on continence evolved favorably after revision surgery or medical treatment in all, but one case. CONCLUSION: Our results are consistent with the literature. Complications and the re-interventions are frequent and should lead to a multidisciplinary information and evaluation of the patient in preoperative care. LEVEL OF PROOF: 3.

Stereotactic cysto-ventricular catheters in craniopharyngiomas: an effective minimally invasive method to improve visual impairment and achieve long-term cyst volume reduction.

Craniopharyngiomas are typically located in the sellar region and frequently contain space-occupying cysts. They usually cause visual impairment and endocrine disorders. Due to the high potential morbidity associated with radical resection, several less invasive surgical approaches have been developed. This study investigated stereotactic-guided implantation of cysto-ventricular catheters (CVC) as a new method to reduce and control cystic components. Twelve patients with cystic craniopharyngiomas were treated with CVC in our hospital between 04/2013 and 05/2017. The clinical and radiological data were retrospectively analysed to evaluate safety aspects as well as ophthalmological and endocrine symptoms. The long-term development of tumour and cyst volumes was assessed by volumetry. The median age of our patients was 69.0 years and the median follow-up period was 41.0 months. Volumetric analyses demonstrated a mean reduction of cyst volume of 64.2% after CVC implantation. At last follow-up assessment, there was a mean reduction of cyst volume of 92.0% and total tumour volume of 85.8% after completion of radiotherapy. Visual acuity improved in 90% of affected patients, and visual field defects improved in 70% of affected patients. No patient showed ophthalmological deterioration after surgery, and endocrine disorders remained stable. Stereotactic implantation of CVC proved to be a safe minimally invasive method for the long-term reduction of cystic components with improved ophthalmological symptoms. The consequential decrease of total tumour volumes optimised conditions for adjuvant radiotherapy. Given the low surgical morbidity and the effective drainage of tumour cysts, this technique should be considered for the treatment of selected cystic craniopharyngiomas.

Management of pelvic organ prolapse of ruptured and extruded bladder from a rare complication of vaginal hysterectomy: a case presentation.

BACKGROUND: The prolapse of a ruptured and extruded bladder after vaginal hysterectomy is rare in clinical practice. We report the case of a significant mass that prolapsed from the vagina after a vaginal hysterectomy in a multiparous postmenopausal woman. CASE PRESENTATION: A 67-year old multiparous postmenopausal Chinese woman was found to have a significant mass extruding from the vagina after a vaginal hysterectomy. The mass was a ruptured and everted bladder, and the diagnosis was confirmed after physical and imaging examinations and urethral catheterization. The patient underwent an emergency operation for mass reduction, bladder repair, and partial colpocleisis under general anesthesia. She recovered without prolapse or urinary drainage complications after 35 months of follow-up. CONCLUSIONS: The present case serves as a guide for the management of patients with pelvic organ prolapse. The condition of patients should be carefully evaluated before surgery, and individualized operation should be performed. Careful postoperative follow-up is crucial for the timely exclusion of complications, especially in elderly patients with persistently increased abdominal pressure.

A novel, nonopiod-based treatment approach to men with urologic chronic pelvic pain syndrome using ultrasound-guided nerve hydrodissection and pelvic floor musculature trigger point injections.

INTRODUCTION: Urological chronic pelvic pain syndrome (UCPPS) represents a group of pain symptoms relating to patients with pelvic pain for which treatment is largely unsatisfactory. The objective of this study is to analyze the effects of a novel treatment strategy in males suffering from UCPPS. METHODS: This retrospective, institutional review board-approved study analyzed eight male patients aged 24 to 61 with UCPPS. All the patients had a trial of antibiotic therapy, NSAIDs, and pelvic floor physical therapy before the study. The Visual Analog scale (VAS) and Functional Pelvic Pain scale (FPPS) were collected pretreatment. While continuing physical therapy, patients underwent weekly ultrasound-guided pelvic floor trigger point injections to the iliococcygeus, pubococcygeus, and puborectalis with lidocaine 1%. Concomitantly, patients received peripheral nerve hydrodissection performed on the pudendal nerve and the posterior femoral cutaneous nerve. The first two injections combined 1% lidocaine with dexamethasone, while the next four injections consisted of 1% lidocaine with traumeel (a homeopathic, plant-derived anti-inflammatory medication). At the 6-week follow-up, each patient retook the VAS and FPPS. RESULTS: The mean age of our patients was 31.8 years and the average duration of symptoms of the UCPPS was 21 months. Pretreatment, the mean VAS was 3.3 (STD 1.7) and the mean VAS posttreatment was 1.8 (STD 1.4); P < .05; 95% CI, 0.73 to 2.27. The mean FPPS pretreatment was 11.0 (STD 8.0) and the mean FPPS posttreatment was 6.3 (STD 5.3); P < .05; 95% CI, 0.03 to 9.22. CONCLUSION: Our results show promise for a novel, nonopioid-based treatment for UCPPS.

Changes in bladder function with time following cystostomy in rats.

AIMS: To investigate bladder function patterns following cystostomy and determine the best time window for cystometric evaluation of bladder function in conscious rats. MATERIALS AND METHODS: Cystostomy was performed in rats of the first seven groups; thereafter, cystometry was performed in the designed time interval. Noncystostomy rats of group 8 voided freely as control. Basal bladder pressure (Pves.basal ), maximum bladder pressure (Pves.max ), bladder threshold pressure (Pves.thre ), voiding interval (VI), bladder contraction duration (CD), bladder compliance (ΔC), voided volume (VV), postvoiding residual urine (PVR), and bladder capacity (BC) were recorded and compared with cystostomy groups, with VV, PVR, BC compared with the control values. Bladders were collected after the urodynamic study for weighing, hematoxylin-eosin, and Masson staining to investigate pathological changes. RESULTS: Pves.basal , Pves.max , and Pves.thre trended downward, while BC, VI, VV, and ΔC trended upward on days 1 to 5 postcystostomy. BC and VV significantly decreased on days 1 to 3 postcystostomy compared with control values; on days 5 to 15 postcystostomy, Pves.basal , Pves.max , Pves.thre , VI, VV, BC, and PVR were stable, and BC, VV, and PVR showed no significant differences from the control values. However, on day 21 postcystostomy, BC increased significantly compared with the controls. Bladder weight increased in the cystostomy groups compared with the controls. Pathological analysis showed severe acute bladder inflammation on days 1 to 3, mild inflammation on days 5 to 15, and increased collagen deposition in bladder tissue on day 21 postcystostomy. CONCLUSION: Cystometric evaluation of bladder function in conscious rats is best performed on days 5 to 15 postcystostomy.

Navigated neuroendoscopy combined with intraoperative magnetic resonance cysternography for treatment of arachnoid cysts.

Endoscopic cystocysternostomy or cystoventriculostomy is the treatment of choice in patients with symptomatic intracranial arachnoid cysts. There are no objective diagnostic tests for reliable intraoperative evaluation of the effectiveness of performed stomies. The aim of this prospective open-label study is to demonstrate for the first time the usefulness of intraoperative cysternography performed with the low-field 0.15-T magnetic resonance imager Polestar N20 during endoscopic cysternostomies. The study was performed in patients operated for middle fossa arachnoid cysts (n = 10), suprasellar cysts (n = 4), paraventricular or intraventricular cysts (n = 6), and a pineal cyst (n = 1). The operations were performed with use of a navigated neuroendoscope. Intraoperative magnetic resonance (iMR) cysternography was performed before and after the cystostomy. In each case, iMR cysternography was safe and could show clearly the cyst morphology and the effectiveness of performed endoscopic cystostomies. In six cases, iMR cysternography had a significant influence of the surgical decision (p = 0.027). The rate of inconsistency between the intraoperative observations and iMR imaging-based findings was 29%. A good contrast flow through the fenestrated cyst walls correlated with a good long-term clinical outcome (ρ = 0.54, p < 0.05) and good long-term radiological outcome (ρ = 0.72, p < 0.05). Intraoperative low-field MR cysternography is a safe and reliable method for assessment of the efficacy of performed endoscopic cystostomies and has significant influence on the surgical decision. It may be reliably used for prediction of the long-term clinical and radiological outcome.

Calculation of postoperative bone healing of cystic lesions of the jaw-a retrospective study.

OBJECTIVES: There is a long history of studies into cystic lesions of the jaws. However, there is little data on postoperative bone regeneration. The aim of the study was to calculate the size of the residual bone lesions after cystostomies and cystectomies to predict the postoperative bone healing. MATERIAL AND METHODS: This retrospective study focused on patients undergoing cystectomy (n = 114) or cystostomy (n = 86), who were treated for cystic lesions between 2010 and 2015. New formulas were developed to measure the decrease in lesion sizes using the craniocaudal and mesiodistal diameters from preoperative as well as postoperative radiographs (panoramic radiographs, CT scans, CBCT). With these predictive models (calculated by linear regression analyses), it is possible to calculate how the lesions would shrink using initial size of the cyst and time after surgery for both dimensions. RESULTS: After cystostomy, the mesiodistal size was initial size 6.0 + 0.7 × initial size - 9.4 × time. The craniocaudal size was 5.1 + 0.7 × initial size - 7.3 × time. After cystectomy, the mesiodistal size was 0.4 + 0.7 × initial size - 8.4 × time. The craniocaudal size was 0.4 + 0.5 × initial size - 6.4 × time (R2 = 0.59 and 0.67, respectively). CONCLUSION: These formulas are suggested to be used to calculate residual size of bone lesion after cystostomy and cystectomy to predict postoperative bone healing. CLINICAL RELEVANCE: The formulas are based on deliberately simple measurement using only panoramic radiographs to encourage their application in daily clinical practice.

Clinical evaluation of the multifunctional suprapubic catheter in patients requiring permanent suprapubic cystostomy: A prospective randomised trial in a single centre.

AIMS AND OBJECTIVES: To assess the clinical effect of the multifunctional suprapubic catheter (MSC) on occurrence of cystospasm, catheter occlusion, the catheter-related urinary tract infection and remission of overactivity bladder, by comparing with the conventional suprapubic catheter (CSC) in patients with permanent suprapubic cystostomy. BACKGROUND: The conventional suprapubic catheter usually presents with high incidence of catheter-associated complications. DESIGN: A prospective randomised clinical trial in a single centre. METHODS: Between January 2014 and January 2015, a total of 91 consecutive patients with permanent suprapubic cystostomy were prospectively randomised into two groups: the MSC group (n = 43) and CSC group (n = 48). RESULTS: Our results showed that the total times of cystospasm in the MSC group were significantly less than that in the CSC group during the follow-up time (p < .001). In addition, the mean spasmodic duration per time in the MSC group was significantly shorter than that in the CSC group (p < .001). Besides, catheter occlusions were observed in 23 (25.27%) patients, including 5 (11.63%) in the MSC group and 18 (37.50%) in the CSC group (p = .005). The lower rate of positive urine culture was also found in the MSC group but with no significant difference (p = .540). Furthermore, the urodynamic measurement data demonstrated that the patients in the MSC group had a greater remission rate of overactivity bladder after catheter change (p < .001). CONCLUSIONS: The present data showed that the multifunctional suprapubic catheter could significantly reduce the incidence of catheter occlusion, ameliorate the symptom of cystospasm and relieve the overactivity bladder, but have no influence on the catheter-related urinary tract infection. RELEVANCE TO CLINICAL PRACTICE: The application of our self-devised multifunctional suprapubic catheter may result in better management of the patients with permanent suprapubic cystostomy.

Vesicostomy button: how is it placed, in whom, and how is quality of life affected?

PURPOSE: The vesicostomy button has been shown to be a safe and effective bladder management strategy for short- or medium-term use when CIC cannot be instituted. This study reports our use with the vesicostomy button, highlighting the pros and cons of its use and complications. We then compared the quality or life in patients with vesicostomy button to those performing clean intermittent catheterization. MATERIALS AND METHODS: Retrospective chart review was conducted on children who had a vesicostomy button placed between 2011 and 2015. Placement was through existing vesicostomy, open or endoscopically. We then evaluated placement procedure and complications. A validated quality of life questionnaire was given to patients with vesicostomy button and to a matched cohort of patients performing clean intermittent catheterization. RESULTS: Thirteen children have had a vesicostomy button placed at our institution in the 4 year period, ages 7 months to 18 years. Indications for placement included neurogenic bladder (5), non-neurogenic neurogenic bladder (3), and valve bladders (5). Five out of 7 placed via existing vesicostomy had leakage around button. None of the endoscopically placed buttons had leakage. Complications were minor including UTI (3), wound infection (1), and button malfunction/leakage (3). QOL was equal and preserved in patients living with vesicostomy buttons when compared to CIC. CONCLUSION: The vesicostomy button is an acceptable alternative to traditional vesicostomy and CIC. The morbidity of the button is quite low. Endoscopic insertion is the optimal technique. QOL is equivalent in patients with vesicostomy button and those who perform CIC.

[Long-term follow-up of continent cystostomy with the Mitrofanoff procedure: 5 years later]. / Évaluation à long terme des cystostomies continentes de type Mitrofanoff chez l'adulte : résultats à 5 ans.

INTRODUCTION: This study analyzed long-term functional outcome of continent catheterizable channels with the Mitrofanoff procedure, their continence, complications and the satisfaction of the patients. MATERIAL AND METHOD: Data from patients who underwent a Mitrofanoff procedure at our institution from June 1997 to March 2015 were retrospectively collected. All patients were contacted at the end of the study, a survey was submitted to them. RESULTS: Sixty-seven patients underwent a continent cystostomy with the Mirtrofanoff procedure. Forty-five patients had the inclusion criteria: 18 years old or older, no previous urinary diversion with a minimum of 6 months of follow-up. The cohort comprised mainly neurologic bladder (84 %) with spinal cord injuries (54 %) or spina-bifida patients (15 %). Median age was 35 years old [22-49]. Median follow-up was 64months [39-90]. The surgical procedure used an appendicular channel: 30 patients (67 %) or a continent ileal plasty: 15 patients (33 %). At the end of follow-up: 88 % patients have a full cystostomy continence, 89 % full uretral continence. Twenty-nine patients had one (41 %) or more reinterventions. Reasons for the 58 reinterventions were: stomal stenosis (31 %), uretral incontinence (29 %), cystostomy incontinence (15 %), lithiasis (9 %). Those reinterventions were done with a local surgery (31 %) or an endoscopic surgery (35 %). Overall early adverse events (<30days) or delayed (>30days) adverse events were similar (P=0.93) in appendicovesicostomy group or continent ileal plasty group. Ninety-four percent patients described a satisfactory urinary comfort. The cystostomy was considered esthetic by 71 %, its realization allowed an improvement of the quality of life for 89 % of them. CONCLUSION: Continent channels in adults demonstrate favorable long-term outcomes even if reinterventions could be necessary to maintain a continent and catheterizable channel. Despite reinterventions, patients remain satisfied by the Mitrofanoff procedure which facilitate the process of clean intermittent catheterization. LEVEL OF EVIDENCE: 4.

Urethral Rest with Suprapubic Cystostomy for Obliterative or Nearly Obliterative Urethral Strictures: Urethrographic Changes and Implications for Management.

PURPOSE: Precise preoperative characterization of urethral stricture is important for surgical planning. A period of urethral rest by a suprapubic cystostomy tube may aid in stricture characterization and affect the surgical approach. In this study fellowship trained reconstructive urologists compared the radiographic characterization of anterior urethral strictures before and after a period of urethral rest. We then determined how this changed the planned operative approach. MATERIALS AND METHODS: We queried our prospectively maintained urethroplasty database at our institution for men with an anterior urethral stricture who underwent retrograde urethrogram and voiding cystourethrogram before and after preoperative suprapubic cystostomy tube placement. A total of 29 men were identified for analysis. To minimize responder fatigue 20 pairs of radiographs were selected at random. All images before and after suprapubic tube placement were interpreted in random order by 11 fellowship trained reconstructive urologists. Interpretation included stricture length, diameter, location and surgeon operative plan. Preplacement and post-placement results were compared. Post-placement stricture length was also compared to intraoperative length. ICC was used to evaluate homogeneity among the urologists. Linear regression analysis was performed to determine the association of post-radiographic length after tube placement with intraoperative stricture length. RESULTS: Imaging agreement among interpreting urologists was satisfactory (ICC 0.72). There was no statistically significant difference in stricture length before vs after suprapubic tube placement. Of the images 23% were considered obliterative before tube placement while 58% were obliterative after placement (p = 0.0005). Mean ± SD post-placement radiographic and intraoperative stricture length was 3.0 ± 2.6 and 3.8 ± 3.3 cm, respectively (p <0.0001). Deviation between the radiographic and intraoperative lengths increased with stricture length (slope 0.26, p = 0.0023). The surgeon operative plan changed 47% of the time, including to an excision approach in 37% of cases. CONCLUSIONS: Despite optimal urethral imaging with a suprapubic tube in men with high grade stricture reconstructive urologists underestimated length by an average of almost 1 cm. This underestimation was less for shorter strictures and it increased with stricture length. In addition, a period of urethral rest resulted in more frequent stricture obliteration, which was associated with a change in the planned operative approach about half of the time. If urologists do not place a suprapubic cystostomy tube prior to urethroplasty for high grade stricture, the operative plan should account for the stricture being tighter than it may appear.

Impact of Adjuvant Urinary Diversion versus Valve Ablation Alone on Progression from Chronic to End Stage Renal Disease in Posterior Urethral Valves: A Single Institution 15-Year Time-to-Event Analysis.

PURPOSE: Long-term progression to end stage renal disease of valve ablation alone vs ablation followed by additional urinary diversion were compared among children with stage 3 chronic kidney disease due to posterior urethral valves. MATERIALS AND METHODS: We performed a retrospective study of children with posterior urethral valves and stage 3 chronic kidney disease treated at a single institution between 1986 and 2011. The 3 treatment groups were classified as group 1-valve ablation alone, group 2-ablation plus subsequent vesicostomy and group 3-ablation followed by ureterostomies and/or pyelostomies. Baseline demographic characteristics were analyzed. Statistical analyses compared the incidence of time to end stage renal disease among the intervention groups using the Fisher-Freeman-Halton exact test and Kaplan-Meier analysis with the log rank test. Cox regression was used to determine predictors of end stage renal disease progression. RESULTS: A total of 40 eligible patients were included in the study (group 1-14 patients, group 2-13 patients, group 3-13 patients). Baseline characteristics and post-intervention estimated glomerular filtration rate revealed no significant between-group differences. A statistically significant difference in progression to end stage renal disease was noted within 1 year after diagnosis of stage 3 chronic kidney disease among the treatment groups (log rank test p=0.02). However, cumulative end stage renal disease incidence at 15-year followup showed no statistical difference (log rank test p=0.628). Cox regression analysis determined that bilateral renal dysplasia (HR 2.76, 95% CI 1.21-6.30) and estimated glomerular filtration rate 60 ml/minute/1.73 m2 or greater after intervention (HR 0.23, 95% CI 0.09-0.61) were predictive of the likelihood of progression to end stage renal disease. CONCLUSIONS: Urinary diversion following valve ablation in children with stage 3 chronic kidney disease associated with posterior urethral valves may temporarily delay progression to end stage renal disease. However, no long-term benefit was noted from diversion in the ultimate incidence of end stage renal disease, suggesting that these interventions should be seen as a temporizing measure. Bilateral renal dysplasia and post-intervention estimated glomerular filtration rate are independent variables predicting overall chronic kidney disease progression.

National Trends in the Management of Primary Vesicoureteral Reflux in Children.

PURPOSE: In September 2011 the AAP (American Academy of Pediatrics) released updated guidelines for the evaluation of children 2 to 24 months old with a febrile urinary tract infection. We documented the impact of the guideline on diagnosis and surgical management of vesicoureteral reflux at U.S. children's hospitals. We hypothesized that voiding cystourethrogram studies and the vesicoureteral reflux treatment rate decreased concurrent with the national guideline release. MATERIALS AND METHODS: The Pediatric Health Information System was queried for children (younger than 18 years) with primary vesicoureteral reflux and their antireflux surgical history from January 2004 to June 2015. Voiding cystourethrogram orders were recorded. Interrupted time series analysis quantified trends surrounding several seminal vesicoureteral reflux publications (2007) and guideline publication (2011). RESULTS: A total of 43,341 voiding cystourethrogram encounters (male 23,946 [55.3%]) were identified for patients at a median age of 3 months (IQR 1-20). For all children monthly voiding cystourethrogram orders increased (+1.0 to +1.6 encounters per month, p <0.034) to September 2011, then sharply declined by 106 encounters per month from September to October 2011 (p <0.001) then did not change significantly (p=0.096, R2=0.79). For those children 2 to 24 months old with a urinary tract infection (3,379 records; male 1,384 [41.0%], median age 4 months [IQR 3-7]) voiding cystourethrograms gradually increased from January 2007 to September 2011 (+0.1 encounters per month, p=0.036), then similarly decreased by 21 encounters per month from September to October 2011 (p <0.001), then did not change significantly (p=0.064, R2=0.78). Overall 28,484 procedures for primary vesicoureteral reflux were identified (male 5,950 [20.9%], median age 4.8 years [IQR 2.5-7.2]). Total surgical procedures did not change significantly until October 2011, then declined (-1.5 procedures per month, p <0.001, R2=0.66). CONCLUSIONS: The number of voiding cystourethrograms ordered nationally in all children and those with a urinary tract infection decreased sharply with the 2011 AAP urinary tract infection guideline release and did not change thereafter. A steady decline in procedures for primary vesicoureteral reflux occurred after October 2011.

Impact on quality of life and sexual satisfaction of continent cystostomy with enterocystoplasty in an adult neurologic population.

AIMS: To evaluate long-term general and urinary quality of life (QOL) and sexual satisfaction in adult neurologic patients undergoing continent cystostomy surgery associated with a bladder enlargement to treat neurogenic lower urinary tract dysfunction. METHODS: Monocentre, retrospective series of adult neurologic patients who underwent continent cystostomy with bladder enlargement and followed-up in the long-term. We assessed during follow-up, urinary and renal function and patients filled QOL questionnaires on general QOL, sexuality and urinary (short form Qualiveen) disability. RESULTS: Fifty-three patients were included and followed-up 77 months on average. Rates of patients' satisfaction, stomal and urethral continences were respectively of 98.7% (n = 51), 94.1% (n = 48), and 80.4% (n = 41). Impact of surgery on general QOL and autonomy were strong and positive (respective mean scores of 4.8 and 4.7 on a scale ranging from 1 to 5). Mean overall urinary Qualiveen QOL score was 0.8 (0.09-2.67) indicating a low negative impact of urinary disability on QOL. In patients <45 years, 52.6% (n = 10) reported a moderate to important improvement of their sexuality after surgery. Renal function remained stable during follow-up. CONCLUSION: In the long-term, continent cystostomy with bladder enlargement provides great satisfaction to almost most patients. It has a strong positive impact on general and specific urinary QOL, patients' autonomy and urinary continence. In young patients a positive impact on sexuality was also noticed. These encouraging data, that need to be confirmed, constitute interesting information to provide to neurologic patients to help them deciding whether they are willing to undergo continent cystostomy surgery.
