RESUMEN

PURPOSE: This study describes the management of urinary incontinence (UI) in eight girls with congenital pouch colon (CPC) associated with anorectal malformation (ARM). METHODS: From 2013 to 2015, six girls with CPC and UI underwent bladder neck reconstruction (BNR). Four girls had complete UI (CUI) and two girls partial UI (PUI). From 2019 to 2023, four girls, including two with failed BNR, underwent bladder neck closure (BNC) and augmentation cystoplasty (AC) with a continent stoma. Subtypes of CPC were Complete CPC (n = 7) and Incomplete CPC (n = 1). All girls had a double vagina; short, wide urethra; and reduced bladder capacity with an open, incompetent bladder neck (BNI). During BNR, a neourethra was constructed from a 1.5-2 cm-wide and 1.5-3-cm-long trigonal strip. During BNC, AC was performed using a 20 cm ileal segment (n = 3) and by a colonic pouch segment, preserved during earlier colorraphy (n = 1). Continent stoma included a Monti's channel (n = 3) and appendicovesicostomy (n = 1). RESULTS: BNR produced moderate improvement of UI (n = 2), while UI was still very severe (n = 4). During BNC, intraoperative complications included iatrogenic vaginal tears (n = 4). Early complications included partial dehiscence of the ileocystoplasty (n = 1), partial adhesive small bowel obstruction (n = 1), and difficulty in stomal catheterization with prolonged drainage from the pelvic drain (n = 1). Late complications included unilateral grade II vesicoureteric reflux (n = 2) and vesicovaginal fistula (VVF) (n = 2) needing trans-vaginal closure in one girl. Urinary stones (n = 2) with stomal leakage of urine in one girl needed open cystolithotomy twice (n = 1), and endoscopic lithotripsy (n = 1). At follow-up, all patients have high overall satisfaction with the procedure and their continence status. CONCLUSIONS: BNC with AC and a catheterizable stoma satisfactorily achieves continence in girls with CPC and UI, vastly improving quality of life. If lower urinary tract (LUT) anatomy is favorable, BNR with/without AC can be the initial surgical procedure. BNC should be the primary procedure in girls with unfavorable LUT anatomy and for failed BNR. LEVEL OF EVIDENCE: IV.

RESUMEN

Bladder neck contracture after prostate surgery is a rare but feared complication. The treatment of choice is endoscopic incision or resection of fibrotic tissue. In case of ineffective transurethral correction, bladder neck reconstruction has to be done. In this report, we present a complicated case treated with combined transurethral and laparoscopic bladder neck reconstruction with buccal mucosal graft inlay. Using retrograde endoscopy fibrotic tissue in the bladder neck was resected to achieve a smooth and wide prostate cavity. After that the laparoscopy performed. The retropubic space is created and prostatic urethra opened via longitudinal prostatic-vesical incision. Buccal mucosal graft was fixed in place. Bladder and prostatic urethra were closed with resorbable suture. Two weeks after surgery the urethral catheter was removed and adequate voiding reestablished. After eleven months patient had no urination complaints and any sings of recurrence. Thus, the combined surgical approach for bladder neck reconstruction using buccal mucosa inlay may be a durable option for treatment of recalcitrant bladder neck contracture.

RESUMEN

PURPOSE: To review the current status of robotic-assisted laparoscopic surgical techniques for bladder neck procedures in children with incontinence secondary to neurogenic bladder. METHODS: A comprehensive review of the literature on robotic-assisted bladder neck procedures was conducted, with a focus on articles published in the last 25 years. These data were subsequently compared to published series of open bladder neck procedures and published results from robotic-assisted bladder neck reconstruction series completed at our institution. RESULTS: The principle bladder neck procedures for incontinence in pediatric patients with neurogenic bladder include: Artificial Urinary Sphincter, Bladder Neck Sling, Bladder Neck Closure, and Bladder Neck Reconstruction. Continence rates range from 60 to 100% with a lack of expert consensus on the preferred procedure (or combination of procedures). Robotic-assisted approaches are associated with longer operative times, especially early in the surgical experience, but demonstrate equivalent continence rates with potential benefits including low interoperative blood loss, improved cosmesis, and decreased intra-abdominal adhesion formation. CONCLUSIONS: Robotic-assisted procedures of the bladder neck are safe, feasible, follow the same steps and principles as those of open surgery and produce equivalent continence rates. Robotic-assisted techniques can be adapted to a variety of bladder neck procedures and safely expanded to selected patients with the previous open abdominal surgery.

RESUMEN

BACKGROUND: Treatment in children and adolescents with a neurogenic bladder is primarily conservative with the goal of preserving the upper urinary tract combined with a good reservoir function of the bladder. However, sometimes-even in childhood-conservative management does not prevent the development of a low-compliant bladder or overactive detrusor. MATERIAL & METHODS: After a systematic literature review covering the period 2000-2017, the ESPU/EUAU guideline for neurogenic bladder underwent an update. RESULTS: In these patients, surgical interventions such as botulinum toxin A injections into the detrusor muscle, bladder augmentation, and even urinary diversion may become necessary to preserve the function of the upper (and lower) urinary tracts. The creation of a continent catheterizable channel should be offered to patients with difficulties performing transurethral clean intermittent catheterization. However, a revision rate of up to 50% needs to be considered. With increasing age continence of urine and stool becomes progressively more important. In patients with persistent weak bladder outlets, complete continence can be achieved only by surgical interventions creating a higher resistance/obstruction at the level of the bladder outlet with a success rate of up to 80%. In some patients, bladder neck closure and the creation of a continent catheterizable stoma is an option. CONCLUSION: In all these patients close follow-up is mandatory to detect surgical complications and metabolic consequences early.

RESUMEN

BACKGROUND: Girls' pelvic fracture bladder neck avulsion and urethral rupture is rare however it causes great morbidity. The management is complex and not standard yet. We report our experience and a technique of bladder neck reconstruction with anterior bladder wall flap. METHODS: We retrospectively analysed data of 5 girls with pelvic fracture bladder neck avulsion and urethral rupture admitted to our institution from July 2017 to October 2019. They all came to our institution with a suprapubic tube. Patients' trauma was all initially treated at other hospitals, 4 had suprapubic cystotomy and 1 had urethral realignment. One girl also had three other urethroplasties at other hospitals. We took pubectomy, posterior ureth roplasty and bladder neck reconstruction with anterior bladder wall flap in these 5 girls. Post-operative assessments included voiding cystourethrography, uroflowmetry and urethroscopy after urethral catheter removal. Verbal consent to participate was obtained from the parent or legal guardian of the children. RESULTS: Operation time ranged from 120 to 180 min. Follow-up time is 12 to 27 months. Uroflowmetry showed that maximum urine flow rate improved significantly. Cystourethrography indicated good continuity of the urethra. Two girls had urinary incontinence postoperatively but were continent 3 months later. One patient developed vesical-abdominal fistula and got repaired by surgery 6 months later. She was continent ever since. Other complications were not observed during the follow-up period. CONCLUSIONS: Our method of bladder neck reconstruction using bladder flap as a patch is feasible and provides good continence, especially for those with serious bladder neck avulsion and urethral rupture caused by extensive trauma and those who had posttraumatic urethral distraction needed second repair.

RESUMEN

PURPOSE OF REVIEW: Significant variance exists in the management of duplex collecting system ureteroceles (DSU). There is a great spectrum in classification, management, and surgical interventions. The practice of performing bladder level operations for vesicoureteral reflux (VUR) and trigonal anatomic distortion, either after ureterocele puncture or in a single setting, has come into question as to whether all DSU patients require it. In this review, we sought to discuss DSU management trends and the need for bladder reconstruction in these patients, as well as to describe our institution's practices. RECENT FINDINGS: Recent advances regarding DSU management revolve around differing surgical approaches, although adequately powered randomized control trials are lacking. These approaches include nonoperative management, various forms of endoscopic puncture, ureteroureterostomy, and most recently upper pole ureteral ligation. A common theme appears to reflect the acceptance that "less is more" when it comes to managing DSU. There is no consensus for the decision to treat or the surgical approach of DSU. Ureteral reimplantation and bladder neck reconstruction appears to be unnecessary in a significant portion of the DSU population, but ureterocele treatment needs to be individualized. There is an ongoing need for large, multi-institutional randomized control trials to evaluate this further.

RESUMEN

BACKGROUND: Prostate cancer is the sixth most common cancer worldwide and will include about 30% of all malignancies in men. Since the initial report of the anatomic radical prostatectomy, refinements in the surgical technique have been made. Several studies show that bladder neck preservation (BNP) during radical prostatectomy makes improve early return of urinary continence, erectile function or both. However, some clinical trials have suggested little difference between the return of continence while using modifications. In this study, we compared outcomes of BNP and bladder neck reconstruction (BNR) during radical retropubic prostatectomy (RRP). MATERIALS AND METHODS: This prospective study was performed on 60 patients at a referral university hospital from March 2010 to March 2012. Study population was all patients candidate for RRP (RRP in this period. All patients divided into two groups, A and B (30 patients in each group). Group A (n = 30) who preserved bladder neck (BNP) and Group B (n = 30) who had BNR. Prostate specific antigen (PSA) before and at 2, 6, 9, 12 and18 months after surgery, anastomotic stricture symptoms, positive bladder neck margin, Gleason score and urine incontinence were compared between two groups. Also, we compared bladder neck contracture, urinary continence and positive surgical margin rates after BNP and BNR while retropubic prostatectomy in 24 months period follow-up. RESULTS: The mean age of the patients was 61.81 ± 7.15 years (range, 50-74 years). After a follow-up period of 24 months, the PSA rising was not different between the two groups. After 2 months, 19 (63.33%) of patients in A group and the same number in B group were continent (P = 0.78). Stricture of the bladder neck at the anastomosis site requiring transurethral dilation occurred in 7 (23.33%) and 3 (10.0%) patients in groups A and B, respectively (P = 0.04). CONCLUSION: Although there was no difference in prevalence and duration of return of urinary continence after the operation between two groups, but results of our study showed that stenosis of the bladder neck was lower in BNP. Hence in the group of BNP, need for further operation and overflow incontinency due to the obstruction of urinary tract will be less likely than BNR and patients have better long time (24 months) urinary continence.

RESUMEN

INTRODUCTION: Epispadias, which occurs on the more mild end of the Bladder Exstrophy Epispadias Complex (BEEC) spectrum, presents still with a wide range of severity in boys, from mild glanular epispadias to penopubic epispadias with severe urethral and bladder neck defects. Surgical management ranges from isolated epispadias repair to epispadias repair with bladder neck reconstruction (BNR) with or without pelvic osteotomies. OBJECTIVES: We aimed to evaluate outcomes in epispadias treated at three institutions prior to formation of a formal collaboration. In addition, we sought to delineate outcomes based on anatomic severity at time of diagnosis, and initial procedure performed in cases of penopubic epispadias. METHODS: IRB approved databases were retrospectively queried at three institutions for patients who underwent repair of epispadias between 1/1993 and 1/2013. Degree of epispadias, age and technique at initial repair, and self-reported continence status at last follow-up were recorded. Continence was categorized as: wet, intermediate (dry 2-3 h), or dry, while also distinguishing those who void and those who require clean intermittent catheterization (CIC). Those not seen since 1/1/2015, younger than 10 years at last follow up, or in whom continence data were not recorded were excluded. RESULTS: A total of 48 boys were identified; 36 met inclusion criteria. The epispadias cohort consisted of 8 glanular epispadias (GE) (22%); 8 penile epispadias (PE) (22%), and 20 penopubic epispadias (PPE) (56%) with a median follow-up of 11.3 years (3.2-26.2 years). Overall, 33 of 36 (92%) boys void per urethra. Within the group that voids, 19/33 (58%) are completely dry, while 6/33 (18%) are wet. Among patients who underwent initial epispadias repair without concurrent or subsequent bladder neck reconstruction, continence rates were: GE 63% (5/8); PE 75% (6/8); PPE 71% (5/7). Among the 9 boys with PPE who underwent initial epispadias repair with concurrent BNR, 22% (2/9) were dry with no further surgeries. Overall, 8/20 (40%) of boys with PPE void with complete dryness. DISCUSSION: This multi-center retrospective review of continence in epispadias demonstrates that even some boys with glanular and penile epispadias can have challenges with continence, and boys with penopubic epispadias may remain wet despite careful preoperative assessment of bladder neck functionality and concurrent BNR. CONCLUSION: Continence outcomes in boys with all degrees of epispadias can be variable. Even boys with more distal defects may have significant bladder neck deficiency. And those with the most severe form of epispadias may require bladder neck reconstruction to achieve continence.

RESUMEN

BACKGROUND: This study aims at investigating the continence outcome in primary epispadias patients treated at a tertiary center. The authors hypothesized that additional continence procedures following primary epispadias repair is not routinely needed. METHODS: Patients treated for primary epispadias at the authors' institution between 2007 and 2019 and toilet trained, were identified from a prospective maintained database. Males underwent chordee correction, urethroplasty and glanuloplasty. Females underwent genitoplasty with reduction urethroplasty. If continence was not achieved by 4-5 years of age, pelvic floor muscle (PFM) biofeedback therapy was performed. Other continent procedures were discussed with family/patient if still incontinent. PRIMARY OUTCOME: urinary continence. SECONDARY OUTCOMES: PFM biofeedback therapy, continence surgery, hydronephrosis. Type of epispadias, age at repair and follow-up presented as median was also reported. RESULTS: Thirty-three patients (29 males) were included. Twelve had penopubic epispadias, 13 glanular/penile, 4 duplicated urethra, 4 females. Median age at repair: 2 years (IQR 1-3), at follow-up: 8 years (IQR 6-10). Daytime continence: 100 % in penile/glanular; 33 % in penopubic and 75 % in duplicated urethra. Nighttime continence: respectively 92 %, 50 % and 100 %. 24 % of males were intermittently incontinent. All patients except one voided urethrally. One patient underwent bladder neck closure, ileocystoplasty and Mitrofanoff. One girl achieved daytime continence, 2 were intermittently incontinent, one continuously incontinent. All were enuretic. 38 % of boys and 100 % of girls had biofeedback therapy. None had hydronephrosis/renal impairment. CONCLUSIONS: Most children with primary epispadias can achieve social urinary continence spontaneously or with the support of PFM biofeedback therapy. Other continence procedures should be reserved for patients who do not attain satisfactory continence. LEVEL OF EVIDENCE: Treatment study - level IV.

RESUMEN

PURPOSE: Complete female epispadias, which occurs much more rarely than classic bladder exstrophy in females, is thought to have a more benign clinical course. We hypothesized that patients with complete female epispadias are more likely to have a larger bladder capacity and achieve voiding continence than females with classic bladder exstrophy. MATERIALS AND METHODS: After obtaining institutional review board approval, females with complete female epispadias or classic bladder exstrophy were identified from an institutionally approved prospective database. We retrospectively reviewed the charts of 22 patients with complete female epispadias and 23 with female classic bladder exstrophy, including 3 with delayed primary closure. RESULTS: Patients with complete female epispadias presented later and underwent the first reconstructive procedure at an older age than patients with classic bladder exstrophy. Patients with complete female epispadias had lower initial and final age adjusted bladder capacity than those with classic bladder exstrophy but the bladder growth rate did not differ between the groups. When patients with complete female epispadias were stratified by age at initial reconstruction, there was no difference in final age adjusted bladder capacity or the bladder growth rate. There was also no statistical difference between the groups in the number of surgeries, continence rate from initial reconstruction, bladder neck reconstruction success or need for a continent stoma. CONCLUSIONS: This study suggests that females with classic bladder exstrophy who undergo successful primary closure have higher initial and final age adjusted bladder capacity than females with complete female epispadias but with a similar growth rate. This may reflect the creation of outlet resistance at a younger age than in those with complete female epispadias. However, no difference was identified between patients with complete female epispadias who initially underwent repair before vs after age 1 year. Patients with complete female epispadias undergo procedures to achieve continence that are similar to those in patients with classic bladder exstrophy.

RESUMEN

AIM: To evaluate the outcome of innervation preserving sphincteroplasty along with anatomical bladder neck reconstruction (IPS-ABNR) compared to classic Young-Dees-Leadbetter (YDL) bladder neck reconstruction in exstrophy with insufficient bladder capacity requiring detubularized-ileocystoplasty. MATERIALS AND METHODS: Sixteen male patients of exstrophy bladder who required ileocystoplasty from 2004 to 2010 were randomized into group A (n = 7) and group B (n = 9). After detubularized-ileocystoplasty with Mitrofanoff stoma and ureteric reimplantation in all, group A received YDL bladder neck repair while group B received IPS-ABNR repair through a midline scrotoperineal approach. Outcome measurement included operative and postoperative problems, continence, and upper tract status. RESULTS: In group A, two had incompetent bladder neck with gross incontinence, while four had a dry interval of more than 3 h without the ability of voiding per urethra. In group B, seven patients had dry interval of more than 3 h with an ability of urethral voiding and midstream holding in five. CONCLUSIONS: Exstrophy patients requiring augmentation cystoplasty and repaired with IPS-ABNR can achieve dynamic bladder outlet resistance with adequate leak point pressure and ability to void voluntarily with midstream holding capability. The children had the satisfaction of voiding per urethra with ability to stop in midstream similar to that in normal children.

RESUMEN

The role of a bladder neck sparing (BNS) technique in radical prostatectomy (RP) remains controversial. The potential advantages of improved functional recovery must be weighed against oncological outcomes. We performed a literature review to evaluate the current knowledge regarding oncological and functional outcomes of BNS and bladder neck reconstruction (BNr) in RP. A systematic literature review using on-line medical databases was performed. A total of 33 papers were identified evaluating the use of BNS in open, laparoscopic and robotic-assisted RP. The majority were retrospective case series, with only one prospective, randomised, blinded study identified. The majority of papers reported no significant difference in oncological outcomes using a BNS or BNr technique, regardless of the surgical technique employed. Quoted positive surgical margin rates ranged from 6% to 32%. Early urinary continence (UC) rates were ranged from 36% to 100% at 1 month, with long-term UC rate reported at 84-100% at 12 months if the bladder neck (BN) was spared. BNS has been shown to improve early return of UC and long-term UC without compromising oncological outcomes. Anastomotic stricture rate is also lower when using a BNS technique.

RESUMEN

BACKGROUND: Following successful closure of patients with classic bladder exstrophy (CBE), the next major milestone is the establishment of urinary continence. Prior to determining the most appropriate continence surgery, it is imperative to reach an adequate bladder capacity minimum of 100 cc in order to make the decision between bladder neck reconstruction (BNR) or continent stoma, with or without augmentation cystoplasty (AC). OBJECTIVE: To examine the timing of when patients achieve threshold bladder capacity for BNR eligibility. We hypothesize most patients will achieve an adequate bladder capacity (100 cc) by 7 years old when continence surgeries will begin to be considered. STUDY DESIGN: An institutional database of 1388 exstrophy patients was retrospectively reviewed for CBE patients after successful primary bladder closure. Bladder capacities were measured via gravity cystography and data presented as descriptive statistics. The cohort was stratified by location, neonatal (≤28 days) or delayed closure period and osteotomy status. The bladder capacities were categorized to either reaching goal or not and a cumulative event analysis was performed. The event being reaching 100 cc capacity or greater and time being the number of years between bladder closure and attainment of goal capacity. RESULTS: 253 patients met inclusion criteria between 1982 and 2019. The majority were of male gender (72.9%), had their closure performed at the authors' institution (52.5%), within the neonatal period (80.7%), and without an osteotomy (51.7%). 64.9% of patients reached goal bladder capacity. There were no significant differences in those who did or did not achieve goal except for clinical follow up. Cumulative event analysis demonstrated a median time of 5.73 years (95% CI 5.2-6.20) corresponded with a 50% event probability of reaching goal capacity. Cox-proportional hazards showed location of closure was significantly associated with hazards of reaching goal bladder capacity (HR = 0.58, CI 0.40-0.85, p = 0.005). Based on this model, the median time to event would be 5.20 years (95% CI 4.76-5.80) for cases done at the authors' hospital and 6.26 years for those performed at an outside hospital (95% CI 5.77-7.24). CONCLUSIONS: These findings help surgeons counsel families appropriately on the odds of attaining goal capacity at various ages. For those who do not reach 100 cc by five years of age, it helps further characterize the odds of requiring a continent stoma with bladder augmentation and the best timing for reconstructive surgery in order to safely gain urinary continence. Families may also be assured that most patients would have the breadth of surgical options when it comes to continence as more than half of patients reached the bladder capacity threshold.

RESUMEN

Introduction: Patients with neurogenic urinary incontinence due to an incompetent outlet may be offered bladder neck reconstruction, but the quest for the perfect surgical-outlet procedure continues. Our aim was to characterize continence and complications after modified Mitchell urethral lengthening/bladder neck reconstruction (MMBNR) with sling and to introduce a modification of exposure that facilitates subsequent steps of MMBNR. Methods: A single-institution, retrospective cohort study of patients who underwent primary MMBNR between May 2011 and July 2019 was performed. Data on demographics, urodynamic testing, operative details, unanticipated events, continence, bladder changes, and additional procedures were collected. A 2013 modification that permits identification of the incompetent bladder neck prior to urethral unroofing was applied to the last 17 patients. The trigone and bladder neck are exposed via an oblique low anterolateral incision on the bladder. Ureteral reimplantation is not routinely performed. Focal incision of the endopelvic fascia after posterior plate creation limits breadth of blunt dissection for sling placement. Descriptive statistics were utilized. Results: A total of 25 patients (13 females) had MMBNR with sling at a median age of 10 years [interquartile range (IQR) 8-11]. Bladder augmentation was performed concurrently in 14/25 (56%) patients. At a median of 5.0 (IQR 3.9-7.5) years follow-up after MMBNR, 9/11 (82%) without bladder augmentation and 13/14 (93%) with bladder augmentation had no leakage per urethra during the day without further continence procedures. Of the three patients with persistent incontinence, two achieved continence with bladder wall Botox injection (overall continence 24/25, 96%). New and recurrent vesicoureteral reflux was noted in five patients and one patient, respectively. Two patients required subsequent bladder augmentation for pressures and one other will likely require it. None have required bladder neck closure or revision. Conclusion: MMBNR with sling provides promising continence per urethra in neurogenic bladder with low need for secondary continence procedures. Ongoing modifications may achieve elusive total continence.

RESUMEN

BACKGROUND: Many surgical procedures have been developed to improve continence in myelomeningocele patients. Our modification of the Mitchell bladder neck reconstruction involves removal of a diamond-shaped wedge of the anterior bladder neck, tubularization of the bladder neck and urethra to increase outlet resistance, and addition of a bladder neck autologous fascial sling. OBJECTIVE: We aimed to evaluate rates of continence and re-operation in children with myelomeningocele undergoing this Modified Mitchell bladder neck reconstruction. STUDY DESIGN: We retrospectively identified children with myelomeningocele having undergone bladder neck reconstruction at our tertiary care referral center from 2012 to 2016. RESULTS: We identified twelve patients with myelomeningocele undergoing this modified bladder neck reconstruction with sling, four female and eight male, median age at the time of surgery was 7 years old. After initial bladder neck reconstruction with sling only 33% were dry. All patients with bothersome leakage after reconstruction underwent bladder neck bulking. Two patients of twelve (17%) ultimately underwent bladder neck closure and achieved dryness. 58% of patients ultimately achieved continence (Summary Figure). DISCUSSION: Our modification of the bladder neck reconstruction with autologous fascial sling showed midterm rates of incontinence near 60%, with initial post-operative continence at 33%. Our patients, however, required higher rates of reoperation (43%) than previous results would suggest (27%). The first line of re-treatment was bladder neck bulking, but this showed low success. While this procedure is minimally invasive and safe, reasonable expectations of efficacy should be established with families when offering this option. Two patients (17%) required bladder neck closure to achieve dryness. While bladder neck closure is often considered a procedure of last resort, both of these patients were immediately dry. Perhaps bladder neck closure should be considered earlier in our algorithm of surgical continence. CONCLUSION: Our rates of continence with the Modified Mitchell bladder neck reconstruction with a fascial sling were similar to prior bladder neck reconstructions. We did find higher rates of reoperation, and further modifications are warranted to continue to improve continence after surgical procedures in the myelomeningocele population. Select cases may warrant early consideration of bladder neck closure.

RESUMEN

Objective: To evaluate the feasibility of three bladder neck reconstruction (BNR) techniques in laparoscopic radical prostatectomy (laparoscopic RP) and their effects on urinary continence. Methods: We retrospectively analyzed 121 patients with organ-confined prostate cancer, who underwent laparoscopic RP in our center from March to December 2018. Three BNR techniques-zero o'clock reconstruction (ZOR), six o'clock reconstruction (SOR), and three/nine o'clock reconstruction (T/NOR)-applied in patients with large bladder opening after prostate resection are described comprehensively. Demographic and perioperative data were collected and analyzed using Pearson's chi-square and one-way analysis of variance test. Multivariate analysis was performed to explore predictors that affected continence recovery in 24 hours, 1 month, 3 months, and 6 months after catheter removal. Results: Laparoscopic RP was performed in all patients, wherein 37, 35, 34, and 15 patients underwent bladder neck preservation, ZOR, SOR, and T/NOR techniques, respectively. There were more high-risk patients and larger mean prostate volume in groups with BNR techniques. Perioperatively, patients with reconstruction techniques had longer operation and anastomosis time, more estimated blood loss, and more positive margin status. Nevertheless, there was no significant difference among four groups regarding continence recovery in 24 hours, 1 month, 3 months, and 6 months after catheter removal. On multivariable analysis, positive apical margin and long anastomosis time were independent adverse predictors of continence recovery in 24 hours. Large prostate volume and positive apical margin were adverse factors of continence recovery at 1, 3, and 6 months. Conclusion: Three different kinds of BNR techniques were safe and feasible in laparoscopic RP and had no different impact on continence recovery. Positive apical margin, large prostate volume, and long anastomosis time were independent adverse predictors of continence.

RESUMEN

Purpose: To review the current status of bladder neck procedures for incontinence in pediatric patients, focusing on the increasing role of robotic-assisted laparoscopic surgical techniques. Methods: A comprehensive review of the literature on open and robotic-assisted bladder neck procedures was conducted, with a focus on articles published in the last 20 years. This data was subsequently compared with published results from robotic-assisted bladder neck reconstruction series completed at our institution. Results: The principal bladder neck procedures for incontinence in pediatric patients include: Artificial Urinary Sphincter, Bladder Neck Sling, Bladder Neck Closure and Bladder Neck Reconstruction. Continence rates range from 60 to 100% with a lack of expert consensus on the preferred procedure (or combination of procedures). Robotic-assisted approaches are associated with longer operative times, especially early in the surgical experience, but demonstrate equivalent continence rates with potential benefits including: low intraoperative blood loss, improved cosmesis, and decreased intra-abdominal adhesion formation. Conclusions: Robotic-assisted procedures of the bladder neck are safe, feasible, follow the same steps and principles as those of open surgery and produce equivalent continence rates. Robotic-assisted techniques can be adapted to a variety of bladder neck procedures and safely expanded to selected patients with previous open abdominal surgery.

RESUMEN

We report on the results of a literature review regarding the indications and results of operations to increase bladder outlet resistance to achieve dryness in children with neurogenic sphincter incompetence (NSBD). The relative advantages and disadvantages of injection of bulking agents, periurethral slings, bladder neck reconfiguration, artificial sphincters, and bladder neck closure based on a literature review and our combined clinical experience are discussed. Based on this review and our experience, we propose that periurethral injection of bulking agents is not justified as a primary treatment. Likewise, operations that reconfigure the bladder neck are not very useful since most patients also require bladder augmentation and an abdominal catheterizable channel. Bladder neck slings with autologous tissues are effective, mostly in females bur in the majority of patients a bladder augmentation is necessary. There is a role also for implantation of artificial urinary sphincters but when done as an isolated procedure, close monitoring to detect possible detrusor changes is needed. Bladder neck closure is an effective measure when other methods have failed.

RESUMEN

OBJECTIVES: Primary female epispadias encompasses a spectrum of disease, presenting with a variable degree of incontinence. We hypothesized that although perineal urethrocervicoplasty can be a successful first-line procedure in patients with normal bladder, a more radical reconstruction was necessary to achieve continence in cases lying at the most severe end of the spectrum. Our aim was to assess the results of a surgical management using perineal approach in girls with normal bladder capacity, and Kelly radical soft-tissue mobilization (RSTM) in patients with inadequate bladder, based on the assumption that bladder capacity (BC) is a reliable marker of epispadias severity. STUDY DESIGN: Prospective inclusion of incontinent girls with female epispadias referred to a single institution. Patients with normal BC were treated with perineal urethrocervicoplasty (PUCP, group 1). Patients with small bladder underwent RSTM (group 2). Follow-up was at 1, 3, 6, and 12 months postoperatively, then annually, including physical examination, renal ultrasound at each visit, continence status, and estimation of functional/maximal BC. The main study outcome was continence status at the age of 5 years or later, if postoperative follow-up was >12 months. RESULTS: From 2006 to 2017, 16 consecutive children were prospectively included in this study, at a median age of 39 months (5-102 months). Seven girls were included in group 1 and underwent PUCP; at the last follow-up, five out of seven were dry by day (4/5 day and night), although three out of five required bladder-neck injection after perineal reconstruction due to stress incontinence. Two patients with persistent incontinence and absence of BC increase after PUCP subsequently underwent RSTM. Eleven patients with low BC (56% [10-94%] of expected BC) were included in group 2 (9 without prior surgery, 2 after PUCP failure). Among the eight evaluable patients, eight out of eight achieved diurnal continence, and 3/8 were fully continent. One girl with obstructive micturition required clean intermittent catheterization. DISCUSSION: The traditional approach of female epispadias based on staged reconstruction (urethroplasty followed by bladder-neck reconstruction) raised concerns regarding the risk of non-physiological obstructive micturition. The perineal approach was suggested as an alternative, with reported diurnal continence rates of 60-80%, but less than 50% of nocturnal continence, presumably in relation with limited bladder capacity. In cases selected within the most severe end of the epispadias spectrum, the Kelly RSTM seems to offer excellent continence rates. CONCLUSION: A tailored approach to female epispadias, based on perineal reconstruction in favorable cases, and radical soft-tissue mobilization in severe cases, seems to yield good continence outcomes in the long term.

RESUMEN

INTRODUCTION: Patients with neurogenic bladder frequently also have bowel dysfunction and a simultaneous urologic and colorectal reconstruction is possible. We present our experience with combined reconstructive procedures using robot-assisted laparoscopy, and demonstrate the utility of a minimally invasive approach that considers both the bowel and bladder management of these patients. METHODS: We retrospectively reviewed all patients who underwent combined bowel and urologic reconstruction at our institution since the start of our multidisciplinary robotic program. RESULTS: Seven patients were identified in our cohort with a mean age of 6.4 years (3.8-10.1 years). Six patients had myelomeningocele and 1 had caudal regression. Malone appendicostomies were placed in all 7 patients. A split appendix technique was used as a conduit in 5 patients, in situ appendix in 1, and neoappendicostomy with cecal flap in 1. Six patients had a Mitrofanoff appendiceal conduit created, while 1 patient had a sigmoid colovesicostomy for urinary diversion. Five patients required bladder neck repair. One patient had stenosis of the Mitrofanoff and one patient had an anastomotic leak of the sigmoid anastomosis. The average operating time was 526 minutes (313-724 minutes). The median length of stay (LOS) was 5 days (4-7 days), excluding one outlier who suffered an anastomotic leak and had an extended LOS (50 days). All patients who underwent continent bladder reconstruction are dry on their current catheterizing regimen, 6/7 are clean with antegrade flushes. CONCLUSION: Patients with neurogenic bladder often have coexisting bowel dysfunction, which provides an opportunity to reconstruct both organ systems simultaneously and achieve social urinary and bowel continence. Before committing to any intervention, the surgeon should consider both the urologic and gastrointestinal needs of the patient, and perform the needed procedures simultaneously. We describe a number of combined operations aimed at bowel and bladder management that can be performed safely using robot-assisted laparoscopy.
