[Laparoscopic radical cystectomy with intracorporeal creation of a continent urinary diversion. Future or present?]

[Radical cystectomy - pro laparoscopic]

Although the technical feasibility of laparoscopic radical cystectomy (LRC) has been proven and the procedure has been accepted in the EAU guidelines 2011 as a valid alternative, its actual position has to be determined. On the one hand the advantages of LRC (less blood loss, lower transfusion rates, shorter analgesia time) have been proven in retrospective studies; however, the technical difficulties of purely laparoscopic urinary diversion result in very long operating times and in cases of a laparoscopic-assisted creation of a neobladder, the question of the advantage of this approach remains doubtful. Despite case reports of port metastases and peritoneal carcinosis following laparoscopic and robot-assisted radical cystectomy, there is no difference in terms of oncological long-term data (up to 10 years) between laparoscopy and open surgery performed at centres of excellence. Evidently, the curative options for the patients do not depend on the type of surgery (open versus minimally invasive) but on the efficacy of adjuvant treatment strategies (polychemotherapy). Currently it is believed that LRC should be considered for patients with low risk of progression (pT1-2). The final position of laparoscopic radical cystectomy can only be evaluated in a multicentric randomized controlled trial.

Laparoscopic radical prostatectomy has become an equivalent alternative to the open retropubic approach, offering the advantages of minimally invasive surgery. It is being applied increasingly in Germany and the rest of Europe. Whether the surgical robot da Vinci will be used for this procedure to the same extent as in the United States is unpredictable because of high investment and maintenance costs. Similarly, laparoscopic sacrocolpopexy has proven to be a viable option compared to open transabdominal or transvaginal surgery, showing a significant reduction in postoperative morbidity. The value of radical cystectomy is controversial despite proven feasability. On one hand, the technical difficulties of purely laparoscopic urinary diversion result in very long operating times, and in the case of the laparoscopically assisted creation of a neobladder, the advantage of this approach has to be questioned. On the other hand, a maximum rate of 30% of local recurrences and distant metastases indicates at least poor patient selection. In conclusion, this procedure should be limited to a few experienced centers.

[Reconstructive procedures in laparoscopic urology]

The introduction of laparoscopic pyeloplasty was the first step towards the development of suturing and knotting techniques. The final breakthrough came with the development of radical prostatectomy since the performance of the urethrovesical anastomosis required highly developed skills in reconstructive surgery. For most laparoscopic surgeons suturing and knot tying became quite familiar henceforth. As a consequence, the interest for other reconstructive procedures has increased tremendously since. Within a very short time pyeloplasty was developed to a surgical standard, and the results compare very favorably with open surgery. A very attractive method is the ureteral reimplantation according to the psoas hitch technique, which, however, does not completely duplicate the open surgical operation. Many patients can potentially be attracted by sacrocolpopexy to treat genital prolapse. The long-term success rate is 92% which is excellent for this indication. Urinary diversion following cystectomy is usually not performed completely intracorporeally, but laparoscopically assisted.
