Objective: To characterize the relationship between surgeon-staff familiarity and the time required to perform an operation. Summary Background Data: The clinical and operational efficiency of operating rooms is a driver of hospital finances and patient outcomes. Surgeon-staff familiarity is an important focus for quality improvement and process optimization. Methods: A retrospective cohort study was performed analyzing operations performed at 4 academic hospitals between July 1, 2019 and December 31, 2023. Exclusion criteria (urgent operations, 2-specialty cases, low surgeon/specialty volume in data set, scheduled length > 8 hours) were applied to limit heterogeneity. The exposure of interest was familiarity between the surgeon and the allied health staff (scrub technicians and circulating nurses) present during an operation (represented as the median staff experience with the index surgeon in the previous 180 d). The primary outcome was whether the actual case length was (vs. was not) 10% shorter than the scheduled case length (“shorter case length”). A secondary outcome was the quantification of the difference between the observed and expected case length and whether the surgical time (cut-close) was shorter. Results: A total of 257,645 operations performed by 25 different specialties comprised the analyzed cohort. Higher levels of surgeon-staff familiarity were associated with a higher likelihood of a shorter case length (observed:expected ratio = 1.16 [1.14–1.18] for high/high levels of familiarity, compared with 0.90 [0.88–0.91] for low/low levels of familiarity). Greater familiarity was also associated with case lengths that were shorter relative to scheduled case length (high/high levels of familiarity 8.7% shorter than low/low levels, P < 0.001). Within the 4 most common types of cases, those operations performed by teams with higher levels of familiarity had shorter surgical times (cut-to-close). Conclusions: This study found that operations were more efficiently performed when the scrub technician and circulating nurse staff had a greater recent experience with the primary surgeon. Surgical team familiarity should be considered a focus of operational and clinical excellence.

Importance Urethral diverticulectomy is performed with or without concomitant pubovaginal sling (PVS). Patients with complex UD are more frequently offered concomitant PVS. However, there is paucity of literature comparing postoperative incontinence rates for patients with simple versus complex UD. Objective The objective of this study is to examine postoperative stress urinary incontinence (SUI) rates after Urethral Diverticulectomy without concomitant PVS for both complex and simple cases. Study Design A retrospective cohort study was conducted among 55 patients who underwent Urethral Diverticulectomy from 2007 to 2021. Preoperative SUI was patient-reported and confirmed with cough stress test result. Complex cases were defined as circumferential or horseshoe configurations, prior diverticulectomy, and/or anti-incontinence procedure. Primary outcome was postoperative SUI. Secondary outcome was interval PVS. Complex and simple cases were compared using the Fisher exact test. Results Median age was 49 years (interquartile range, 36–58 years). Median follow-up was 5.4 months (IQR, 2–24 months). Thirty of 55 (55%) cases were simple, and 25 of 55 (45%) complex. Preoperative SUI was present in 19/57 (35%) (11 complex vs 8 simple, P = 0.25). Stress urinary incontinence persisted postoperatively in 10 of 19 (52%) (6 complex vs 4 simple, P = 0.48). De novo SUI occurred in 7 of 55, 12% (4 complex vs 3 simple, P = 0.68). Overall, 17 of 55 (31%) patients had postoperative SUI (10 complex vs 7 simple, P = 0.24). Of those, 8 of 17 underwent subsequent PVS placement (P = 0.71) and 9 of 17 had resolution of pad use after physical therapy (P = 0.27). Conclusions We did not find evidence of an association between complexity and postoperative SUI. Age at surgery and preoperative frequency were the strongest predictors of postoperative SUI in this cohort. Our findings suggest successful complex urethral diverticulum repair does not require concomitant PVS.

Abstract Objective To present the pathologic analysis of female urethral strictures obtained during reconstructive urethroplasty. Methods Nine separate female urethral tissue specimens were obtained during dorsal vaginal graft urethroplasty by a single surgeon (S.P.P.). Samples were serially sectioned and fixed in 10% formalin 6 to 12 hours before routine processing in paraffin blocks. Serial 5-µm sections were subjected to H&E, Masson trichrome, and elastin staining. End point analysis included evaluation for epithelial hyperplasia and cell type, mucosal edema, degree of fibroblast/inflammatory cell infiltrate, and elastin fiber density and distribution. Results Nine specimens were examined. Six specimens had epithelial linings of stratified squamous epithelium overlying fibrosis (67%), 1 had mixed squamous and urothelial epithelium, and 2 had only urothelial epithelium. Two specimens (29%) showed acute injury with prominent squamous papillary hyperplasia, focal erosion, and patchy mucosal hemorrhage. Areas of urethral stricture were variably thickened, with increased, densely packed collagen fibers and associated mucosal lymphocytic inflammation ranging from mild and patchy to focally dense with lymphoid aggregates. The highest elastin fiber density appeared to be associated with vessels and overlying muscle bundles in the submucosa. Conclusions Further elucidation of histopathologic characteristics may illuminate more appropriate therapeutic pathways for female urethral stricture disease management.

Abstract Purpose: A prophylactic ureteral localization stent (PULSe) placed by urologists aids in intraoperative localization and detection of suspected ureteral injury during complex colorectal surgery (CRS) cases. We evaluated the incidence and management of urologic-induced complications secondary to PULSe placement during CRS cases at a single center. Materials and Methods: We performed a retrospective review of all patients who underwent cystoscopy and PULSe placement at the time of CRS over a 12-month period. Bilateral 5 French ×70-cm TigerTail ® (Bard Medical Division, Covington, GA) PULSe devices were placed without assistance of routine fluoroscopy. Results: Ninety-nine patients (mean age, 58.1 years; range, 17–88 years) underwent bilateral PULSe placement, with a male:female ratio of 44:55 and a mean body mass index of 26.8 (17.0–38.6) kg/m 2 . Mean pre- and postprocedural creatinine levels were 0.91 and 1.01 mg/dL, respectively. Twenty-two of 99 (22%) cases utilized a guidewire to aid in placement of PULSe. Four Clavien grade IIIb complications occurred: mucosal edema, reflex anuria, ureteral perforation, and ureteral obstruction secondary to significant clot burden. Three of the grade IIIb complications were managed endoscopically with double-J stent placement. The ureteral perforation case required percutaneous nephrostomy tube placement. Subgroup analysis of the four grade IIIb complications revealed a mean age of 62.3 years, body mass index of 26.98 kg/m 2 , and pre- and postprocedural creatinine levels of 0.95 and 4.83 mg/dL, respectively. Only one of the four grade IIIb complications utilized a guidewire prior to PULSe placement. Conclusions: The incidence of Clavien grade III urologic-induced complications during PULSe placement is approximately 2% (4/188). Mandatory adoption of fluoroscopy and guidewires may be required to minimize complications of PULSe placement.

ObjectiveTo determine long‐term surgical outcomes of salvage autologous fascial sling placement after a failed synthetic midurethral sling.MethodsWomen who had undergone autologous fascial sling placement without concomitant pelvic surgery for a failed synthetic midurethral sling utilizing mesh with a minimum follow up of 36 months were identified. Charts were reviewed, and patients were contacted by telephone. Success was determined by the Patient Global Impression of Improvement. Secondary measures included the Incontinence Severity Index questionnaire, patient recommendation of the autologous fascial sling and need for further incontinence surgery.ResultsA total of 35 patients met the criteria, and 21 were successfully contacted. Of those contacted, the median age at surgery was 67 years (range 53–81 years) and at the time of the survey was 75 years (range 63–84 years) with median follow up of 74 months (range 36–127 years). Preoperatively, 12 patients (57.1%) had urethral hypermobility and 13 patients (61.9%) had mixed urinary incontinence. Eight patients (38.1%) had concomitant sling excision with five of those combined with urethrolysis at the time of the salvage operation. Patient Global Impression of Improvement success was noted in 16 patients (76.2%). A total of 11 patients (52.4%) were dry or had slight incontinence by the Incontinence Severity Index. One patient required additional anti‐incontinence surgery (4.8%). A total of 18 patients (85.7%) recommended the autologous fascial sling. No statistical impact was noted with sling excision (P = 0.62), mixed urinary incontinence (P = 0.61), age at surgery (P = 0.23), age at follow up (P = 0.15), length of follow up (P = 0.71) or first surgery type (transobturator tape vs retropubic; P = 1.00).ConclusionsAutologous fascial sling provides reasonable long‐term success as a salvage operation for failed midurethral slings.
