Laparoscopic radical prostatectomy: preliminary results
Abstract
BACKGROUND: Retropubic and perineal radical prostatectomy are used for curative treatment of localized prostate cancer. More complex urological procedures are now being done with laparoscopy. We present our initial results of transperitoneal laparoscopic radical prostatectomy.
MATERIALS AND METHODS: Twenty laparoscopic radical prostatectomies were performed between May 1998 and May 1999. The mean age at the time of surgery was 64.2 years. There were 14 stage T1c, 5 stage T2a and 1 stage T2b tumors. The preoperative PSA was 9. 3 ng/ml (normal <4 ng/ml). The Gleason score for positive specimens in 6 random echo-guided endorectal biopsies was 5.7. Four trocars were used. Insufflation pressure was 15 mmHg. The seminal vesicles were first dissected. The prostate was dissected free from the anterior face of the rectum to the prostate apex. Then the peritoneum was incised to find the apex of the prostate. The puboprostatic ligaments were isolated and cut, and the dorsal vein complex was ligated and cut to expose the urethra. The bladder neck was opened and dissected free from the prostate. The lateral pedicles were coagulated before sectioning the urethra. The radical prostatectomy specimen was left along the sigmoid colon, the bladder neck was reconstructed, and a urethrovesical anastomosis was performed with 6 interrupted sutures. The prostatectomy specimen was removed intact in a sack by enlarging the umbilical trocar port. All the prostatectomy specimens were processed…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
