“…Historically, after RRP, catheters were left in place for 2-3 weeks [4]. Despite this precaution, BN contractures were reported in 5-32% of patients [30]. With the running anastomosis and the improved visualization of mucosa to mucosa suturing, postoperative bladder neck contractures have been significantly reduced with RALP to 0-3% [30].…”

“…Despite this precaution, BN contractures were reported in 5-32% of patients [30]. With the running anastomosis and the improved visualization of mucosa to mucosa suturing, postoperative bladder neck contractures have been significantly reduced with RALP to 0-3% [30]. The desire by both patient and surgeon for early catheter removal, or perhaps to obviate the need for urethral stenting altogether, has led to novel methods of bladder drainage.…”

Since the introduction of robot-assisted radical prostatectomy (RALP), robotics has become increasingly more commonplace in the armamentarium of the urologic surgeon. Robotic utilization has exploded across surgical disciplines well beyond the fields of urology and prostate surgery. The literature detailing technical steps, comparison of large surgical series, and even robotically focused randomized control trials are available for review. RALP, the first robot-assisted surgical procedure to achieve widespread use, has recently become the primary approach for the surgical management of localized prostate cancer. As a result, surgeons are constantly trying to refine and improve upon current technical aspects of the operation. Recent areas of published modifications include bladder neck anastomosis and reconstruction, bladder drainage, nerve sparing approaches and techniques, and perioperative and postoperative management including penile rehabilitation. In this review, we summarize recent advances in perioperative management and surgical technique for RALP.

“…Technical factors postulated to effect BNC rates include: absence of mucosal eversion, poor vesico-urethral apposition, urinary extravasation, excessive narrowing of VUA and ischemia to the bladder neck or membranous urethra (18)(19)(20)(21)(22). Many groups have postulated that excess suture placement may increase the risk of tissue ischemia to the VUA and thus predispose to VUA (23).…”

MethodsMale porcine bladders were obtained and prostatectomy was performed. The specimens were randomized and VUA were created using 3-point interrupted, 6-point interrupted or 6 point continuous 3-0 monocryl suture. 20Fr catheters were utilized, specifically varying manufacturers (A and B) and catheter balloon shapes (round versus oval). The VUA model was placed within a reproducible pulley system and graduated weights were applied util failure of the catheter balloon or the model VUA. Model failure was defined as either 'VUA rupture', 'Catheter passage through VUA' or 'catheter failure'. ResultsTwenty consecutive porcine bladders were prepared, tested and utilized for analysis. VUA reconstructed with 3-point fixation was more likely to suffer VUA rupture (p=0.025) compared to 6-point interrupted or 6-point continuous VUA. Higher tensile pressure causing catheter balloon rupture (p=0.009) was observed for Manufacturer A. Catheters with ovalballoon shape were more likely to dislodge past the VUA without disruption of the anastomosis (p=0.002). ConclusionsDuring prostatectomy, anastomotic technique and catheter selection can significantly alter the tensile properties of the VUA. Further research is required to validate our findings in clinical models.3

ОбзорыФакторы риска развития и методики коррекции послеоперационного стеноза везикоуретрального анастомоза (обзор литературы) ВведениеРак предстательной железы (РПЖ) является наи-более распространенным злокачественным новообра-зованием у пожилых мужчин (старше 70 лет), которое в странах Европы и США опережает по заболеваемо-сти рак легких и колоректальный рак [1]. РПЖ -важ-ная проблема здравоохранения, особенно в развитых странах с большой долей пожилых людей в общей популяции. По данным как Европейской, так и Аме-риканской ассоциаций урологов, в течение жизни диагноз РПЖ будет поставлен каждому 7-му мужчине. При этом у 80 % заболевших будет диагностирован локализованный РПЖ (стадии T1-2N0M0) [2]. В Рос-сии ситуация, к сожалению, значительно хуже, и на начальные стадии РПЖ приходится лишь 50 % слу-чаев.С тенденцией к увеличению продолжительности жизни мужчин и известной положительной корре-
