[Robotic radical prostatectomy: first 100 patients in Fundació Puigvert]. / Prostatectomía radical robótica: análisis después de 100 casos en la Fundació Puigvert.

OBJECTIVE: We present the 100 first robotic radical prostatectomy with Da Vinci (RRPdaV), corresponding to the first experience in Spain. METHODS: We reviewed the first 100 patients that underwent transperitoneal RRPda performed in Fundació Puigvert between July 2005 and January 2007. All cases were performed by 5 surgeons, being the learning curve for all of them. We analyzed surgical time, blood loss, conversion rate, intra and postoperative complications, hospital stay and days of bladder catheterization. Also, rates and location of surgical margins, as well as functional outcomes with an average follow up of 10.3 months. RESULTS: Mean operating time was 180 minutes (100-310) and blood loss 210 mL (100-390). Blood transfusion was required in 2 cases. There were no intraoperative complications and neither any conversion to open surgery. There were 3 outstanding postoperative events, a compartmentalize syndrome, an acute urinary retention after removal of urethral catheter, and a paresthesias due to brachial plexus compression. Mean hospital stay were 3.7 days. (2-21). We had 21 cases of positive surgical margins (21%). The most frequent location was posterior lateral. 69 of 100 patients (69%) reached early (<3 months) total continence, 91% achieved in 9 months, and remaining 9% required use of at least one pad. Concerning to sexual function, 13 of 100 patients (13%) had preoperative erectile dysfunction, of remaining cases, 62% preserved potency at review, and 38% had postoperative erectile dysfunction. CONCLUSIONS: RRPDAv is a safe and reproducible procedure, and offers promising oncological and functional results with a minimal invasive technique. In spite of include the learning curve of 5 surgeons; we obtain an excellent rate of continence, and an acceptable sexual function. The individual improvement, with more experience, and a longer follow-up, will allow to value evolution of the technique, and it results.

[Transperitoneal laparoscopic partial nephrectomy in the renal tumor treatment]. / Nefrectomía parcial laparoscópica transperitoneal en el tratamiento del tumor renal.

Laparoscopic surgery is a surgical technique the urologist should add to his surgical armamentarium. Its performance tries to mimic the surgical phases of open surgery, and also its indications. Laparoscopic partial nephrectomy is a sophisticated technique that requires wide experience in the performance of endoscopic strategies. We are submitting our experience with 35 laparoscopic partial transperitoneal nephrectomies with a mean follow-up of 25 months. The mean surgical time was 200 minutes, the mean bleeding 190 cc, and the mean hospitalisation five days. Two postoperative bleedings were identified, there were no conversions, and positive margins were notified in two cases, where upon a conservative attitude was adopted.

Clamping of the renal artery in laparoscopic partial nephrectomy: an old device for a new technique.

OBJECTIVE: We describe our experience with the transient clamping of the renal artery during laparoscopic partial nephrectomy for renal cancer with a double loop clamping device, inspired by the Rumel tourniquet. The silastic rubber loop is positioned around the renal artery and clinched, thus achieving arterial occlusion. METHODS: From November 2002 until July 2004, fourteen consecutive patients (mean age of 58 +/- 11.6 years) underwent laparoscopic transperitoneal partial nephrectomy using the silastic rubber clamping device, eight of them on the right side and six on the left side. Hemorrhage of the renal defect was controlled with bipolar electrocoagulation, argon beam coagulation, laparoscopic sutures, surgical and fibrin glue. RESULTS: : The mean surgical time was 198.92 +/- 39.95 min for a mean tumour size of 2.9 +/- 2.32 cm and a mean blood loss of 104.57 +/- 77.69 ml. The clamping device was easily and successfully positioned around the renal artery in 2.05 +/- 0.45 min and the mean warm ischemic time was 25.21 +/- 6.07 min. CONCLUSIONS: The clamping device procures successful atraumatic occlusion of the renal artery during laparoscopic partial nephrectomy without the need for an additional port. As such, it could be considered as an alternative for the laparoscopic bulldog and Satinsky clamp.

Contemporary non-imaging methods in diagnosis of bladder cancer: a review.

The early diagnosis of bladder cancer is central to the effective treatment of the disease. Presently, the detection of bladder tumors relies on cystoscopy and there are no methods available to easily and specifically identify the presence of bladder cancer cells. A variety of new technologies and potential tumor markers are being studied in bladder cancer and some are being translated into clinical use. It is important to realise that all available results on the diagnostic value of tumor markers do not allow firm clinical recommendations, but tests based on biomarkers will undoubtedly influence the management of bladder cancer in the near future.
