Congenital penile curvature: dermal grafting procedure to prevent penile shortening in adults.

OBJECTIVES: We report the results of a derma graft corporoplasty in a selected group of patients with congenital penile curvature (CPC) who refused a simple plication technique for the risk of penile shortening, even if minimal. METHODS: Between January 1995 and January 2004, 15 potent patients with CPC underwent corporoplasty with inguinal derma graft, with or without tunica albuginea plication. Mean age was 26.6 years (range 19-36). Six patients had a simple lateral left curvature, three had a simple lateral right curvature, four had a ventro-lateral left curvature, one patient had a ventro-lateral right curvature, and one patient had ventral curvature. In nine patients the preoperative mean IIEF-5 score was 22.55 (range 21-24). All the patients were evaluated after three, six and 12 months. RESULTS: One graft was placed in one patient (6.6%), seven (46.6%) received one graft and underwent a tunica albuginea plication, four (26.6%) received two grafts, three (20%) received two grafts and underwent tunica albuginea plication. A residual curvature after three, six and 12 months was present respectively in all (100%), seven (46.6%) and one (6.6%) patients. No patients had a decrease of penile length. The mean difference in the IIEF-5 score before and after the surgical procedure was not statistically significant. CONCLUSIONS: Surgical correction of CPC with derma grafts in potent patients restores penile straightening with no postoperative shortening and preserves normal erectile capacity. Patient satisfaction indicates that the proposed technique may be used in selected cases.

Oncologic outcome and continence recovery after laparoscopic radical prostatectomy: 3 years' follow-up in a "second generation center".

OBJECTIVES: Laparoscopic radical prostatectomy in major centers guarantees oncologic and functional results equal to open procedures. In our institution this operation was introduced in 2001 after an adequate training in laparoscopic surgery. We report the oncologic and functional results after 3 years of experience. METHODS: We considered our first 150 patients that had undergone transperitoneal laparoscopic radical prostatectomy. The following parameters were prospectively collected and analyzed: pathological findings, surgical margins, surgical time, blood loss, hospital stay, catheterization, complications, oncologic follow-up and continence. RESULTS: Single positive surgical margins were observed in 26 patients (17.3%) and multiple positive margins in 15 patients (10%). The rates of positive margins in organ confined tumors (pT2a/b) were 11.3%. Preoperative PSA>10 ng/ml (Chi-square p<0.01), pathological stage>pT2 (Chi-square p<0.001) and Gleason score>6 (Chi-square p<0.01) were significantly correlated with positive margins. Major complications occurred in 16 patients (10.7%). The total recurrence rate is 11.7%. The continence rate at 12 months is 91.7%.with 44.3% of patients completely continent at the moment of catheter removal. CONCLUSIONS: Laparoscopic radical prostatectomy in now a well codified operation that, after an adequate training, could be learned and reproduced safely. Actually this is our first choice surgical approach in patients with localized prostate cancer.

Transrectal ultrasound guided implantation of the ProACT adjustable continence therapy system in patients with post-radical prostatectomy stress urinary incontinence: a pilot study.

PURPOSE: We evaluate the feasibility and potential advantages of ProACT system implantation using transrectal ultrasound rather than fluoroscopy for guidance. MATERIALS AND METHODS: The transrectal ultrasound guided procedure was done between June and October 2005 in 7 patients with a mean age of 68.4 years (range 53 to 76) with mild to severe stress urinary incontinence after laparoscopic transperitoneal radical prostatectomy. RESULTS: The ProACT system was successfully implanted in all cases without perioperative complications. Time needed to complete the overall procedure was 15 to 30 minutes. All transrectal ultrasound studies performed during the mean followup of 4.2 months (range 2 to 6) confirmed the exact location of the devices. CONCLUSIONS: ProACT system implantation is feasible using transrectal ultrasound for guidance. Transrectal ultrasound enables excellent imaging of all anatomical landmarks during the entire procedure and it seems to provide considerable advantages over fluoroscopy in terms of safety and accuracy.

The tongue as an alternative donor site for graft urethroplasty: a pilot study.

PURPOSE: Urethroplasty with a buccal mucosal graft provides excellent clinical results but it may also cause oral complications in some cases. The mucosa covering the lateral and under surface of the tongue is identical in structure with that lining the rest of the oral cavity. We evaluated LMGs for urethroplasty. MATERIALS AND METHODS: From January 2001 to September 2004, 8 men 34 to 65 years old (mean age 46.1) with urethral strictures 1.5 to 4.5 cm long were selected for 1-stage dorsal onlay urethroplasty. The site of the harvest graft was the lateral mucosal lining of the tongue. Postoperatively all patients were followed with urethrography, uroflowmetry, cystourethrography and flexible urethroscopy after 3 and 12 months. Successful reconstruction criteria were peak flow rate greater than 15 ml per second and no need for postoperative urethral dilation. RESULTS: Median followup was 18 months (mean 22.1, range 3 to 47). Seven cases were successful. One patient had a partial urethral stricture. In successful cases cystourethrography revealed no significant graft contractures or sacculations and at flexible urethroscopy LMG was almost indistinguishable from native urethra. There were no pain, esthetic or functional complications at the donor site. CONCLUSIONS: Harvesting the LMG is feasible and easy to perform. Compared with the buccal mucosal graft the LMG seems to be associated with less postoperative pain and a minor risk of donor site complications. These preliminary functional and esthetic data are satisfactory.

Laparoscopic radical cystoprostatectomy: our experience in a consecutive series of 10 patients with a 3 years follow-up.

OBJECTIVE: Laparoscopic radical cystectomy is a feasible procedure but there is still controversy if laparoscopic treatment of transitional cell carcinoma (TCC) of the bladder is oncologically safe. We report our experience with laparoscopic radical cystectomy in a consecutive series of 10 male patients with a 3 years follow-up. METHODS: Between June 2001 and July 2002, 10 men age 63 to 74 years (mean 68.8) underwent laparoscopic cystoprostatectomy with urinary diversion for muscle-invasive TCC or pT1 G3 TCC plus carcinoma in situ (Cis) after 2 cycles of intravesical bacille Calmette-Guerin therapy and three or more transurethral resections (delayed cystectomy). RESULTS: Histopathology revealed 2 stage pT1N0 TCC G3 plus Cis, 1 stage pT2aN0 TCC G3 plus Cis, 1 stage pT2bN0 TCC G2, 4 stage pT2bN0 TCC G2-3, 1 stage pT2bN0 TCC G3, 1 stage pT3aN0 TCC G3. The mean follow-up is 30.4 months (range 23-36). No local recurrences, peritoneal carcinosis or trocar-site metastases occurred. Metastases presented in 4 of 10 cases (2 patients with a stage pT1N0 plus Cis and 2 patients with a stage pT2bN0 TCC) respectively after 7, 14, 16 and 28 months. These patients died respectively at 20, 18, 22 and 31 months later. One patient died for unrelated causes. Five patients are alive, free from disease. CONCLUSIONS: Laparoscopic radical cystectomy is feasible and accomplished with low morbidity. Up to now publishing data do not support a verified negative oncological effect of the laparoscopy in the treatment of bladder TCC, but our initial results seem worst than those achieved with open surgery. The experience of other Institutions will help to provide objective evaluation of this new and controvers technique because it is not clearly demonstrated that laparoscopic radical cystectomy is an oncologically safe procedure in the management of bladder TCC. Thus in our opinion it should be still considered experimental.

Laparoscopic radical cystoprostatectomy: a technique illustrated step by step.

OBJECTIVES: Laparoscopic surgery is expanding among urologists as a minimally invasive treatment and may now be applied to treat neoplasms of the pelvic organs. Laparoscopic cystoprostatectomy has still not been well codified and illustrated. We describe a technique of laparoscopic radical cystoprostatectomy that we have developed in 10 patients after practicing in laparoscopic radical prostatectomy. METHODS: Between June 2001 and July 2002, 10 men with bladder cancer underwent laparoscopic cystoprostatectomy with urinary diversion. This report details step by step our 5-port transperitoneal technique with primary access to the seminal vesicles and Denonvillier's fascia, ureters detection after umbilical arteries incision, endopelvic fascia incision and dorsal vein complex control before division of the vesical and prostatic fibrovascular pedicles with a harmonic scalpel. RESULTS: We performed 6 orthotopic ileal neobladders, 2 sigmoid ureterostomies and 2 cutaneous ureterostomies. In all cases no conversion to open surgery was necessary. The mean time to perform the laparoscopic radical cystoprostatectomy, including the lymph node dissection, was 166 minutes (range 150-180). Mean estimated blood loss was 310 ml (range 220-440). Mean hospital stay was 8.1 days (range 7-9) for ileal orthotopic neobladder, 8 days (range 7-9) for sigmoid ureterostomy and 5 days for cutaneous ureterostomy. The mean follow up is 12.3 months (range 5-18). Two patients respectively with stage T2bN0 G2-3 and stage pT1N0 (plus carcinoma in situ) G3 transitional cell carcinoma and surgical margins tumor free had diffusive metastatic disease after 6 months. The other 8 patients are free from disease. CONCLUSIONS: Laparoscopic radical cystectomy is still an operation for pioneers but this procedure may be not strictly relegated to a few academic centers. In our opinion laparoscopic cystoprostatectomy is a feasible, fast, safe and easy procedure and urinary diversion may be performed with a laparoscopic, open or combined approach without reducing the advantages of laparoscopy.

Laparoscopic radical prostatectomy: perioperative complications in an initial and consecutive series of 80 cases.

OBJECTIVES: We retrospectively evaluated the intraoperative and early postoperative complications of the initial experience with the first 80 laparoscopic radical prostatectomies performed at our institution. METHODS: Between January 17, 2001 and July 24, 2002, 80 patients between 53 and 78 years old (mean age 63.8) with clinically localized prostate cancer underwent laparoscopic radical prostatectomy with the Montsouris technique. A total of 24 (30%) staging pelvic lymphadenectomy were performed. The inpatient and outpatient medical records as well as all complications were reviewed. RESULTS: The pathological tumor stage revealed 18 pT2a (22.5%), 29 pT2b (36.25%), 21 pT3a (26.25%), 10 pT3b (12.5%), 1 pT4 (1.25%), 1 pT4 N1 (1.25%). No conversion was necessary in all cases. Mean operative time was 218 minutes (range 150-420) overall, mean blood loss was 376 ml (range 50-1000) and the mean postoperative hospital stay was 4.5 days (range 3-9). The mean and the median duration of bladder catheterization were respectively 11 and 10 days (range 7-23). Injury to the epigastric vessels was detected intraoperatively in 5 cases (6.25%) with immediate hemostasis achieved. There was 1 death (1.25%) 35 days after a cerebrovascular accident occurred on postoperative day 3. We observed 1 (1.25%) postoperative ileus, hemoperitoneum in 5 cases (6.25%), 2 (2.5%) acute urinary retentions, 6 (7.5%) anastomotic leakages, 1 (1.25%) anastomotic stricture, 1 (1.25%) hydrocele and 2 (2.5%) urinary tract infections. CONCLUSIONS: In our initial experience laparoscopic radical prostatectomy was performed with no complications in 77.5% of patients. We observed major and minor complications respectively in 16.25% and 6.25% of the patients. Our series provides evidence that the laparoscopic approach is feasible and associated with acceptable perioperative morbidity.
