INTRODUCTION: With improved understanding of the precise anatomy, surgical techniques during robot-assisted radical prostatectomy (RARP) have been refined, with the aim of improving functional outcomes without compromising oncological adequacy and results. Nevertheless, postoperative urinary incontinence remains a frustrating side-effect. Anatomically, bladder neck (BN) serves as an internal sphincter. The longitudinal fibres of BN may be identified and isolated with a meticulous dissection at the prostato-vesical junction, contributing to earlier return of urinary continence. The purpose of this video is to show an anatomical athermal dissection of BN during RARP. MATERIALS AND METHODS: After incision of endopelvic fascia and anterior defatting, the morphology of prostate not only laterally, but also at the level of bladder-prostatic junction is well visualized. With an athermal dissection of the plane between prostate and bladder we can minimize the traumatic effects on the longitudinal fibres of BN. A cold section of the preserved BN permits the complete preservation of integrity of this sphincteric structure. RESULTS: With this technique we preserve the longitudinal fibres of BN, allowing the sparing of the sphincteric mechanism of BN. The finding of a difficult athermal dissection of these plans may make you suspect the presence of an infiltration, suggesting to sacrifice BN in order to avoid a positive surgical margin. In our series no increase of PSM has been recorded using this technique. CONCLUSIONS: This surgical technique preserving the natural BN mechanism appears to improve urinary continence, allowing at the same time an easy identification of a neoplastic infiltration.

Abstract

INTRODUCTION: With improved understanding of the precise anatomy, surgical techniques during robot-assisted radical prostatectomy (RARP) have been refined, with the aim of improving functional outcomes without compromising oncological adequacy and results. Nevertheless, postoperative urinary incontinence remains a frustrating side-effect. Anatomically, bladder neck (BN) serves as an internal sphincter. The longitudinal fibres of BN may be identified and isolated with a meticulous dissection at the prostato-vesical junction, contributing to earlier return of urinary continence. The purpose of this video is to show an anatomical athermal dissection of BN during RARP. MATERIALS AND METHODS: After incision of endopelvic fascia and anterior defatting, the morphology of prostate not only laterally, but also at the level of bladder-prostatic junction is well visualized. With an athermal dissection of the plane between prostate and bladder we can minimize the traumatic effects on the longitudinal fibres of BN. A cold section of the preserved BN permits the complete preservation of integrity of this sphincteric structure. RESULTS: With this technique we preserve the longitudinal fibres of BN, allowing the sparing of the sphincteric mechanism of BN. The finding of a difficult athermal dissection of these plans may make you suspect the presence of an infiltration, suggesting to sacrifice BN in order to avoid a positive surgical margin. In our series no increase of PSM has been recorded using this technique. CONCLUSIONS: This surgical technique preserving the natural BN mechanism appears to improve urinary continence, allowing at the same time an easy identification of a neoplastic infiltration.
