“…However, the relationship observed is both non-linear and considerably variable between cadavers. This finding supports clinical observations that some USMI cases treated with AUSs will require greater cuff inflation volumes than others to reach continence, with some cases becoming continent following AUS placement without any additional inflation, while others necessitate repeated deflations or removal (Delisser et al 2012, Reeves et al 2012, Gomes et al 2018, Morgan et al 2018. This important patient variation in addition to the intensive follow-up management and The line graphs (a) to (e) display the correlation between maximum recorded urethral pressure and incremental increases in AUS volume for each cadaver Dogs 1 to 5, respectively.…”

“…Outcomes following AUS placement have been reported in prospective (Rose et al 2009) and retrospective studies (Delisser et al 2012, Reeves et al 2012, Currao et al 2013, Gomes et al 2018, Morgan et al 2018. Overall, AUS placement has a good outcome with up to 80% of cases reported as completely continent, without the need for additional medical treatment at 12 months postoperatively (Gomes et al 2018).…”

Objectives To determine whether artificial urethral sphincter filling volume is proportional to peak pressure exerted on the urethra. Materials and Methods Urethral pressure profilometry was performed in five female, medium‐sized, mixed‐breed canine cadavers following artificial urethral sphincter placement. Maximum urethral pressure was recorded following sequential incremental inflation of 0.15 mL and compared to baseline pressure and between dogs using two‐way analysis of variance. Results Artificial urethral sphincter placement in cadavers was associated with an increase in urethral pressure, which was significantly correlated with inflation volume. The correlation was non‐linear and demonstrated considerable individual variation. Maximum urethral pressures after artificial urethral sphincter placement exceeded those reported in conscious continent dogs within a narrow volume range, in which a 0.15 mL infusion more than doubled maximal urethral pressures. Clinical Significance Rapid increases in urethral pressure from the artificial urethral sphincter over a small range of filling volumes (0.15 mL increments) might explain why some clinical cases can become suddenly dysuric following incremental inflations. We suggest that smaller increments of filling (0.05 to 0.1 mL) may achieve finer pressure control.

Introduction and hypothesis Standardized terminology for surgical procedures commonly performed to treat stress urinary incontinence in women is needed to facilitate research, clinical care, and teaching in female pelvic medicine and reconstructive surgery. Methods This report combines the input of members of the American Urogynecologic Society and the International Urogynecological Association, assisted by external referees. Extensive searches of the literature were performed, including Instructions for Use brochures and original source documents where possible. Historical context was considered along with procedural modifications, and expert opinion was included when appropriate. Results A terminology report for the procedures commonly performed to treat stress urinary incontinence in women was produced. Included procedures are midurethral sling, retropubic colposuspension, pubovaginal sling, urethral bulking, and artificial urinary sphincter. Appropriate figures have been included to supplement and help clarify the text. Ongoing review will be performed periodically to keep the document updated and widely acceptable. Conclusions This document is a literature and consensus-based terminology report for surgical procedures to treat stress urinary incontinence in women. Future publications in female pelvic medicine and reconstructive surgery should use this standardized terminology whenever possible.

Objectives: To evaluate the outcome of endoscopic injection of two different bulking agents, glutaraldehyde cross-linked collagen and dextranomer/hyaluronic acid copolymer into the urethral submucosa in female dogs with urinary incontinence caused by urethral sphincter mechanism incompetence. Materials and MethOds: Retrospective review of records and follow-up communication with owners of dogs that received an endoscopically guided urethral bulking procedure. In each dog, either crosslinked collagen (2007 to 2011) or dextranomer/hyaluronic acid copolymer (2012 to 2015) was used.At least three injections were made in a circular arrangement in the midurethral region until the urethral lumen was closed.results: Complete questionnaires were available from 50 of 100 pet owners. The mean interval between the treatment and interview was 67 (range: 57 to 114) months in the cross-linked collagen group and 19 (range: 2 to 48) months in the dextranomer/hyaluronic acid copolymer group.The mean duration of continence was 45•8 months (range: 12 to 84 months) in the cross-linked collagen group and 20•5 months (range: 12 to 48 months) in the dextranomer/hyaluronic acid copolymer group. The success rate at 6 months or more after the procedure was 71% after the injection of cross-linked collagen and 58% after injection of dextranomer/hyaluronic acid copolymer. One minor complication (transient haematuria) occurred in one dog. There were no major complications.clinical significance: Urethral injection of dextranomer/hyaluronic acid copolymer in bitches with urethral sphincter mechanism incompetence is a useful alternative to cross-linked collagen injection, which is no longer available in the European market. Dextranomer/hyaluronic acid copolymer injection is a minimally invasive alternative to surgical procedures and has a low complication rate.
