RESUMEN
Context: Spinal cord injury (SCI) patients with neurogenic bladder and the inability to self-catheterize may require incontinent diversion to provide low-pressure drainage while avoiding the use of indwelling catheters. We demonstrate that in patients with significant functional improvement, the ileovesicostomy can be a reversible form of diversion, with simultaneous bladder augmentation using the same segment of ileum utilized for the ileovesicostomy. Multidisciplinary management should be utilized to assure mastery of intermittent catheterization before urinary undiversion. This technique allows for transition to a regimen of intermittent self-catheterization with excellent functional and urodynamic outcomes.Design: Case Series.Setting: Tertiary care hospital, Philadelphia, Pennsylvania.Participants: Three individuals with an SCI.Interventions: Conversion of bladder management from an incontinent ileovesicostomy to an augmentation ileocystoplasty, with intermittent catheterization.Outcome Measures: Ability to regain urinary continence with preservation of renal function as determined by serum creatinine and renal ultrasound.Results: Three SCI patients who had an incontinent ileovesicostomy developed sufficient functional improvement to intermittently self-catheterize reliably and underwent conversion of ileovesicostomy to ileocystoplasty. For each, the ileovesicostomy channel was taken down and detubularized, then used to create an ileal patch for augmentation ileocystoplasty. Intermittent catheterization was then used for periodic bladder drainage. All achieved large capacity, low-pressure bladders with complete continence and stable creatinine.Conclusion: In motivated SCI patients, it is possible to regain continence by converting the ileovesicostomy into augmentation ileocystoplasty, avoiding the disadvantages of a urostomy. A multidisciplinary collaborative approach facilitates the optimal rehabilitation of SCI individuals.

OBJECTIVE: To identify potential technical factors during initial mid-urethral sling (MUS) placement that contribute to subsequent sling revision procedures. METHODS: A retrospective chart review was performed examining synthetic MUS reoperations at a single institution from 2008-2020. The implanting surgeon's operative note, when available, was critically reviewed with respect to trocar placement, sling location, and tensioning technique. The reoperative report was reviewed for aberrant intraoperative findings relating to the index surgery. RESULTS: A total of 306 women underwent revision of their MUS. Operative reports from the implanting surgeon were available for 276 (90.2%) women. Review of index operative reports revealed 47 unambiguous descriptions of improper technique, including 19 cases of described excessive tensioning and 2 cases of MUS placement despite noted urethral injury during the index case. Indications for reoperation were clinical obstruction (63%), pain (40%), and mesh erosion/exposure (33%). In 186 (67.4%) women, there was an intraoperative finding during the revision that likely contributed to the need for reoperation. Among these 186 women, 110 (59.1%) slings were noted to have been placed too proximally, 78 (41.9%) were over-suspended, and 57 (30.6%) were placed too deep in the periurethral fascia. CONCLUSION: Review of the index operative note and findings at operative re-exploration of MUS surgeries, often reveals evidence that the initial MUS implantation was technically suboptimal. Such findings suggest that intraoperative surgical technique is a critically important factor contributing to postoperative complications in MUS surgery. This underscores the importance of surgical training and adherence to surgical principles during the placement of a synthetic MUS.

Urinary tract fistulas represent a complex group of pathologies that present significant management challenges. While most such fistulas ultimately require definitive surgical management, compromised local tissue quality or other factors often render straightforward simple one layered closure challenging with a substantial risk of failure. Interpositional tissue flaps have become a mainstay of treatment in these circumstances, enabling the delivery of healthy tissue from other locations to the site of pathology. Herein, we present an overview of the assessment and management of complex urinary tract fistulas involving the reproductive and gastrointestinal organs, and the decision to utilize flaps. We review the underlying principles of tissue flaps and classify different types of flaps. We conclude with a discussion of the indications, advantages, disadvantages, and harvesting techniques for the most commonly utilized flaps in urinary tract fistula repair.

A significant workforce shortage of urologists available to serve the US population has been projected to occur over the next decade. Accordingly, much of the management of urologic patients will need to be assumed by other specialties and practitioners. Since primary care physicians are often first evaluate common urologic complaints, it makes sense that these physicians are in an excellent position to intervene in the management of these patients when appropriate. One of the most common complaints in urology is voiding dysfunction. The incidence of voiding dysfunction increases with age, with conservative estimates showing that over 50% of elderly patients suffer. Despite this high prevalence and its negative impact on quality of life, however, few seek or receive treatment, as many do not readily disclose these impactful yet personal symptoms. We sought to summarize the typical presentation, evaluation, assessment and therapeutic options for both male and female patients presenting with voiding dysfunction.

OBJECTIVES: To compare long-term outcomes of men with adverse pathologic features after adjuvant radiation therapy (ART) versus salvage radiation therapy (SRT) after radical prostatectomy at our institution. METHODS: Patients treated with postprostatectomy radiation therapy with pT3 tumors, or pT2 with positive surgical margins, were identified. Cumulative freedom from biochemical failure (FFBF), freedom from metastatic failure (FFMF), and overall survival rates were estimated utilizing the Kaplan-Meier method. Multivariate analyses were performed to determine independent prognostic factors correlated with study endpoints. Propensity score analyses were performed to adjust for confounding because of nonrandom treatment allocation. RESULTS: A total of 186 patients with adverse pathologic features treated with ART or SRT were identified. The median follow-up time after radical prostatectomy was 103 and 88 months after completion of radiation therapy. The Kaplan-Meier estimates for 10-year FFBF was 73% and 41% after ART and SRT, respectively (log-rank, P=0.0001). Ten-year FFMF was higher for patients who received ART versus SRT (98.6% vs. 80.9%, P=0.0028). On multivariate analyses there was no significant difference with respect to treatment group in terms of FFBF, FFMF, and overall survival after adjusting for propensity score. CONCLUSIONS: Although unadjusted analyses showed improved FFBF with ART, the propensity score-adjusted analyses demonstrated that long-term outcomes of patients treated with ART and SRT do not differ significantly. These results, with decreased effect size of ART after adjusting for propensity score, demonstrate the potential impact of confounding on observational research.

BACKGROUND: The overall rate of complications after ankle fracture fixation varies between 5% and 40% depending on the population investigated, and wound complications have been reported to occur in 1.4% to 18.8% of patients. Large studies have focused on complications in terms of readmission, but few studies have examined risk factors for wound-related issues in the outpatient setting in a large number of patients. A review was performed to identify risk factors for wound complications tracked in the hospital and outpatient setting. METHODS: Four hundred and seventy-eight patients underwent open reduction and internal fixation of an ankle fracture between 2003 and 2010 by a single surgeon at a single institution. Demographic characteristics, time to surgery, comorbidities, and postoperative care were tracked. Wound complications were defined as those requiring dressing care and oral antibiotics or requiring further surgical treatment. RESULTS: Of the 478 patients who were followed, six (1.25%) had wounds requiring surgical debridement. Fourteen patients (2.9%) required further dressing care or a course of oral antibiotics. There were significant associations between wound complications and a history of diabetes (p < 0.001), peripheral neuropathy (p = 0.003), wound-compromising medications (p = 0.011), open fractures (p = 0.05), and postoperative noncompliance (p = 0.027). There was a significant difference in age between patients with and without wound complications (p = 0.045). We did not identify a relationship between time to surgery and complications. CONCLUSIONS: These results highlight the difficulty of treating medically complex and noncompliant patient populations. With careful preoperative monitoring of swelling, time to surgery does not affect wound outcome. The failure of the patient to adhere to postoperative instructions should be a concern to the treating surgeon.

Pelvic kidneys are typically asymptomatic, but surgical intervention may be required in select cases. Laparoscopic pelvic nephrectomy is a feasible option. Given the highly variable vascular anatomy, careful surgical planning and meticulous technique are necessary. We present our experience with this minimally invasive approach. A 46-year-old male with a painful, non-functioning left pelvic kidney initially underwent left ureteral stent placement. He was noncompliant and lost to follow up. He re-presented and elected for laparoscopic pelvic nephrectomy. The procedure was performed without complications. Key features included detailed preoperative vascular imaging, ureteral catheterization, optimal port placement, and dissection from a cephalad to caudal direction. Laparoscopic nephrectomy is a safe and efficacious treatment for diseased pelvic kidneys.

OBJECTIVE: To report on assessments of face, content, and construct validity for the commercially available da Vinci Skills Simulator (dVSS). METHODS: A total of 38 subjects participated in this prospective study. Participants were classified as novice (0 robotic cases performed), intermediate (1-74 robotic cases), or expert (≥ 75 robotic cases). Each subject completed 5 exercises. Using the metrics available in the simulator software, the performances of each group were compared to evaluate construct validation. Immediately after completion of the exercises, each subject completed a questionnaire to evaluate face and content validation. RESULTS: The novice group consisted of 18 medical students and 1 resident. The intermediate group included 6 residents, 1 fellow, and 2 faculty urologist. The expert group consisted of 2 residents, 1 fellow, and 7 faculty surgeons. The mean number of robotic cases performed by the intermediate and expert groups was 29.2 and 233.4, respectively. An overall significant difference was observed in favor of the more experienced group in 4 skill sets. When intermediates and experts were combined into a single "experienced" group, they significantly outperformed novices in all 5 exercises. Intermediates and experts rated various elements of the simulators realism at an average of 4.1/5 and 4.3/5, respectively. All intermediate and expert participants rated the simulator's value as a training tool as 4/5 or 5/5. CONCLUSION: Our study supports the face, content, and construct validation attributed to the dVSS. These results indicate that the simulator may be most useful to novice surgeons seeking basic robot skills acquisition.
