Introduction

Retzius space sparing (RSS) during laparoscopic robot-assisted radical prostatectomy (RALP) has been offered as an act that reduces perioperative complications and enables faster gaining of full urinary continence due to bladder anatomy preservation. Retro and trans-peritoneal techniques have been proposed, whereby RSS has been implemented. We sought to explore whether Retzius space reconstruction (RSR) following transperitoneal RALP will be an advantageous step as well.

Methods

One hundred consecutive transperitoneal RALP cases performed by a single surgeon were retrospectively reviewed. The Retzius space has been opened by dissecting the bladder away from the anterior abdominal wall to the level of both internal rings. In the last 50 cases (Group 2) the peritoneal layer has been sutured back thus repositioning the bladder back to the anterior abdominal wall and reconstructing the Retzius space. _x000D_ Peri-operative factors were analyzed and compared between the two groups. Data are given as either number (%) or median (Inter-Quartile Range). _x000D_

Results

Demographic and peri-operative data did not differ between the two groups (Table 1). Intra and post operative complications are detailed in Table 2. As seen, Group 2 demonstrated shorter length of stay (LOS) compared with the control group (Group 1) (p=0.001), as well as faster urinary continence recovery (i.e: 0 pads) (p=0.005). Moreover, lower numbers of Clavien-Dindo grade 3 complications, post-operative ventral hernias and urinary leak were seen in Group 2 compared with Group 1.

Conclusions

RSR following transperitoneal RALP is a simple and efficient step that potentially reduces early and late post operative complications, shortens LOS and accelerates full urinary continence.
