    Ureteral Stents for Impassable Ureteroscopy

    Background: For the narrow ureter that will not accommodate a ureteroscope, it is common practice to place a ureteral stent, to allow subsequent ureteroscopy in the passively dilated ureter. Surprisingly, there are limited data on the effectiveness or safety of these maneuvers. Methods: We retrospectively analyzed patients managed with ureteral stent placement followed by another attempt at ureteroscopy after an initial attempt of flexible ureteroscopy failed because the ureteroscope would not pass up an otherwise normal ureter. Results: Of 41 patients with follow-up who underwent ureteral stenting for this reason, the ureteroscope passed with ease poststenting in 29 (71%) and there was continued resistance in 12. Of these 12 patients, the ureteroscopy was continued despite resistance in 9, while another stent was placed in the remaining 3. Of these three patients, the third attempt at ureteroscopy was successful in two, and further attempts at ureteroscopy were not made after the third attempt failed in one. With a mean overall follow-up of 32 months, two patients (5%) developed ureteral strictures. Both were among nine patients in whom repeat ureteroscopy was performed despite resistance, with a rate of obstruction of 22% in this subgroup. Overall, ureteral stenting allowed successful ureteroscopy in 98% of patients. Conclusions: Ureteral stenting with subsequent ureteroscopy is a successful and safe method of addressing a narrow ureter that initially does not allow passage of a flexible ureteroscope, as long as persistent subsequent attempts to insert the ureteroscope are made only if it passes easily.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140373/1/end.2012.0414.pd

    5% of urothelial carcinoma occurs in the upper urinary tract (UUT), a challenging location to biopsy. We aim to evaluate concordance between biopsy, cytology, and resection specimens in a large upper tract urothelial carcinoma (UTUC) cohort.117 UTUC resections with UUT biopsy and/or cytology specimens from 2000–2016 were retrieved; pathologic material was re-reviewed, evaluated for concordance, and correlated with clinical information. 14% pre-operative biopsies, including 8 from renal pelvis and 6 from ureter, lacked neoplastic diagnoses. 77% diagnostic biopsies included subepithelial tissue; 11% demonstrated reclassification of grade and 30% demonstrated reclassification of invasion status. 26% of renal pelvis UTUC and 36% ureter UTUC were invasive only on resection. Of 18 UTUC reclassified from noninvasive high-grade papillary urothelial carcinoma (HGPUC) to invasive HGPUC, 39% had prior radical cystectomy (versus 8% invasive UTUC and 11% noninvasive UTUC with concordant biopsies). Most high-grade UTUC (88%) and some low-grade UTUC (58%) resections had abnormal cytology results. Biopsy-resection pairs with concordant invasion status and pairs with discordant invasion status showed similar rates of recurrence (38% versus 38%) and metastasis (25% versus 27%). 14% of UUT biopsies lacked diagnostic neoplastic material. Grade concordance between biopsy and resection was high (89%), but 30% of cases showed invasion only on resection. Subepithelial tissue was less commonly present in ureter biopsies, particularly from mid or proximal ureter. UTUC in patients with prior cystectomy were more likely to show invasion on resection but not biopsy

Background In 2013, we developed an education workshop to enhance the teaching skills of surgical fellows. We sought to investigate the feasibility of the monthly educational workshop format and its effect on participant teaching skills. Study Design Surgical and medical education faculty created a broadly applicable curriculum developed from evidence-based teaching principles, delivered across 8 monthly 90-minute weekday sessions. Workshop feasibility and effect were assessed using evaluations, attendance records, and a variety of self-reported surveys. Each session was associated with a specified education action plan to be completed between sessions. Results A total of 13 fellows intended to participate. More than 60% attendance was achieved in 7 of 8 sessions. In all, 11 of 13 fellows were engaged (actual attendance or excused absence) across 75% or more of the sessions. Mean participant satisfaction scores ranged from 4.0 to 4.9 on a 5 point Likert scale across 87.5% of sessions. Postworkshop surveys showed increased understanding of the following: (1) knowledge gaps related to education; (2) the role of education for academic surgeons; (3) educational tools to improve teaching performance; and (4) perceived knowledge and attitudes about teaching in the operating room. An action plan was performed in 43% of cases; the most common reason for nonparticipation was lack of time (38%). Conclusions Our pilot supports the feasibility of an educational workshop series to enhance fellow\u27s educational skills in the area of intraoperative teaching. Participant engagement and satisfaction were high in this self-selected group of initial trainees. Sessions were effective, resulting in a thoughtful self-assessment of teaching skills
