We prospectively tested the safety of routine removal of the catheter as early as 2 to 4 days after laparoscopic radical prostatectomy.Between March 1998 and March 2001, 228 patients underwent laparoscopic radical prostatectomy for clinically organ confined prostate cancer. The last 113 consecutive patients were included in a prospective study according to gravitational cystography performed 2 to 4 days postoperatively. If no leak was seen the catheter was removed. If a leak was apparent the catheter was left indwelling for another 6 days and cystography was repeated.Cystography 2 to 4 days postoperatively showed an anastomosis without a leak in 96 (84.9%) patients who subsequently had the catheters removed. There were 28 patients who had the catheter removed on postoperative day 2, 28 day 3 and 40 day 4. In 17 (15.1%) patients an anastomotic leak was observed, and the catheter was not removed at that time. Of the 96 patients in whom the catheter was removed early 10 (10.4%) had urinary retention that necessitated re-catheterization. This procedure was performed without the need for cystoscopy. After the catheter was removed all patients were able to void 24 hours later. Median followup was 7 months (range 1 to 15) and showed continence rates greater than 93%. No anastomotic stricture, pelvic abscess or urinoma developed in any patient.Patients who undergo laparoscopic radical prostatectomy can have the catheter safely removed 2 to 4 days postoperatively without a higher risk of incontinence, stricture or leak related problems.

Robotics in surgery is a recent innovation. This technology offers a number of attractive features in laparoscopy. It overcomes the difficulties with fixed port sites by restoring all 6 degrees of freedom at the instrument tips, provides new possibilities for miniaturization of surgical tasks and allows remote controlled surgery. We investigated the applicability of remote controlled robotic surgery to laparoscopic radical prostatectomy.Our previous experience with laparoscopic prostatectomy served as a basis for adapting robotic surgery to this procedure. A surgeon at a different location who activated the tele-manipulators of the da Vinci* robotic system performed all steps of the intervention. A scrub nurse and second surgeon who stood at patient side had limited roles to port and instrument placement, exposure of the operative field, assistance in hemostasis and removal of the operative specimen. Our patient was a 63-year-old man presenting with a T1c tumor discovered on 1 positive sextant biopsy with a 3+3 Gleason score and 7 ng./ml. preoperative serum prostate specific antigen.The robot provided an ergonomic surgical environment and remarkable dexterity enhancement. Operating time was 420 minutes, and the hospital stay lasted 4 days. The bladder catheter was removed 3 days postoperatively, and 1 week later the patient was fully continent. Pathological examination showed a pT3a tumor with negative margins.Robotically assisted laparoscopic radical prostatectomy is feasible. This new technology enhances surgical dexterity. Further developments in this field may have new applications in laparoscopic tele-surgery.
