[Laparoscopic radical prostatectomy. Preliminary experience].

OBJECTIVE: Laparoscopic technique has been developed with the aim to decrease the morbidity of the open radical prostatectomy. MATERIAL AND METHODS: From january 2002 to may 2002, 8 patients were treated for prostate cancer with laparoscopic radical prostatectomy. Unilateral linfadenectomy has been carried out in only one patient. We usually employ the transperitoneal technique published by the Montsouris Institute, with some modifications. RESULTS: The main surgical time was 356 minutes (540-240). Transfusion wasn't needed in any case. Intraoperative complications were: 2 bladder injuries, 1 bleeding of the epigastric artery. Postoperative complications were: 1 ileus, 2 compressive neurapraxia, 4 anastomotic fistutas. All complications were treated conservatively. No patient were converted to open surgery. Surgical limits were negatifs in all cases, and the PSA rate was less than 0.1 ng/ml in the first month follow up. CONCLUSION: Laparoscopic radical prostatectomy is a difficult technique, but we think that, the learning curve is getting lower and lower than in the first series. Oncologic results with this technique is similar to the open one. However, laparoscopic approach shows us some benefits such as less bleeding, less time catheterisation, less hospital stay, better continence, better sexual function, better stetic result, less postoperative pain, and finally an earlier back to work.

[Treatment of stenosis in uretero-intestinal anastomosis].

UNLABELLED: We report our experience in the treatment of uretero-enteric anastomotic strictures. Our incidence in this complication is 3.8% in orthotopic bladder substitution and 8.3% in ileal conduict. MATERIAL AND METHODS: We have treated this complication in 6 patients with orthotopic bladder substitution and 4 with ileal conduict. We tried to perform a dilatation with a high pressure balloon and to place a Double-J catheter. RESULTS: In 4 cases we could not introduce the guidewire through the stricture because there was a total stop. In the others 6 cases, one is doing well without Double-J, another one did not tolerate the catheter and we performed an open surgical reanastomosis, 2 kept the catheters until their death due to metastases and the other two continue alive with their catheter periodically replaced. CONCLUSIONS: The direct uretero-enteric anastomoses present less stenoses risk. Endourological techniques should be the first option in treatment of these patients.

[Quality of life in patients treated with orthotopic bladder substitution versus cutaneous ileostomy].

PURPOSE: Nowadays, psychcological and social aspects of treatment of urinary diversion after cystectomy, have become of utmost importance. Body image, potency, continence, emotional distress and dissatisfaction, functional and social activities are majors factors to improve quality of life after surgery. The aim of this study is to compare health-related quality of life after bladder substitution with ileal conduit diversion. MATERIALS AND METHODS: We developed a questionnaire based upon a literature review, to compare health related quality of life between bladder substitution and ileal conduit (45 multiple choice mailed questionnaire). We examined functional and social activities, sexual dysfunction, urinary problems, and body image dissatisfaction. RESULTS: 78 male patients with bladder cancer, were interviewed. 91% of the questionnaires were answered, 48.7% by patients' family and 42.3% by the patients themselves. 6 patients underwent ileal conduit and 27 underwent bladder substitution. Patients with ileal consuit presented higher body image dissatisfaction than those who underwent bladder substitution. When urine leakage occurred it caused more distress to the conduit patients, indicating urinary leakage as their main problem. Bladder substitution patients did not consider continence problems as very important, they had not interrupted social activities such as travelling or seeing friends. 100% of bladder substitution patients would not mind to undergo this operation again, while only 66% of ileal conduit patients would. CONCLUSION: Health-related quality of life is higher after bladder substitution. In our opinion we should use bladder substitution as the standard method of diversion after radical cystectomy for bladder cancer.

[Ureteral stenosis of uretero-ileal anastomosis].

Replacement plasty allows to perform oncology surgery while maintaining body image and preserving renal function. Entero-ureteral anastomosis is a significant element in this procedure where the main responsible for the loss of renal function are stenosis, infection and reflux. Our group has performed 206 orthotopical vesical replacements (November 1981-November 1998), using a direct Wallace-type uretero-ileal anastomosis. An intussusception valve system was used as antireflux mechanism. The number of obstructions, rate of stenosis at the uretero-ileal junction and incidence of valve stenosis were all analyzed as part of the complications occurred over a follow-up period of 54 months (6-183). Findings included 6 stenosis at the uretero-intestinal junction and 2 at the intussusception valve. Two (3.8%) of the uretero-ileal stenosis were earlier and associated to fistula; one was treated with open surgery and one had a double J placed through antegrade percutaneous access. Of the remaining late four, only one was treated with a double J catheter while the other three had to be re-operated. Stenoses of the valvular system (1.2%) were solved with open surgery. From our experience, we believe that direct uretero-ileal implantation with scraping of the ureter is a safe technique with little risk for stenosis at the uretero-ileal junction. Intussusception was used a antireflux system in all cases.

[Orthotopic substitutive cystoplasty in women. Technical modifications in anterior exenteration: results in 9 cases].

OBJECTIVE: The results obtained in 9 female patients who underwent bladder substitution after a modified anterior pelvic exenteration are presented. METHODS: From 1994 to 1999, 9 women underwent bladder substitution after a modified anterior pelvic exenteration that preserved the two distal thirds of the urethra, the pubourethral ligaments and endo-pelvic fascia and limited laterovaginal dissection to preserve the innervation of the striated sphincter for continence. RESULTS: The bladder capacity was 332.9 +/- 35.6 ml and urinary flow was 17.7 +/- 2.9 ml/sec. Seven patients are completely continent and two patients have stress incontinence grade II. None of the patients had difficulty with bladder emptying. Fistula (one case) and diarrhea (one case) were the most important complications. CONCLUSIONS: Our approach is based on a better understanding of the anatomical mechanisms of female continence and the viability of the remaining urethra from the oncologic perspective. This technique achieves a high level of patient satisfaction and quality of life.

[Laparoscopic approach of Dielt's syndrome].

Dielt's syndrome is generally known as nephritic colic due to the dilation of the urinary tract that results from a renal ptosis. In spite of renal ptosis being a commonly seen occurrence, sometimes it can be the cause of a serious painful clinical manifestation. This paper presents one case successfully treated through laparoscopic nephropexy. It also includes a discussion on the various diagnostic and therapeutical techniques.

[Percutaneous renal surgery].

RATIONALE: Analysis of complications resulting from the renal percutaneous approach. METHODS: Between 1990 and 1996, 175 percutaneous surgical procedures were performed by our group. In 69.2% cases, the reason was a lithiasic condition. We also carried out: 35 endopyelotomies, 12 renal cyst resections, 4 stenosis of uretero-ileal anastomosis, 2 diagnostic nephroscopies and 1 pyelic tumour resection. RESULTS: Total rate of complications was 22.2%. Mortality was 0.5% (one case). Surgery had to be terminated in 13 cases for different reasons. Blood transfusions were required in 9 cases. 3 cases of route perforation required extended maintenance of nephrostomy. Infectious problems developed in 9 cases. There were also 2 renocutaneous fistula, one renocolic fistula and one pneumothorax. No significant differences were found between the total number of complications and the type of treatment carried out. There is however a relationship between the lithiasic condition and the haemorrhagic complications and also with the failure of the approach. There are no significant differences between the number of complications and other variables such as age, sex, side, calix approached or duration of surgery. CONCLUSIONS: The percutaneous approach to the kidney can be considered as a technique with a low morbidity-mortality ratio.

[Treatment of urogenital tuberculosis with ofloxacin. Preliminary study].

Ofloxacin is a new fluoride quinolone which has been shown to be active both in vitro and in vivo against Mycobacterium tuberculosis. This prospective study presents the results obtained with a new protocol for the treatment of genito-urinary tuberculosis. The comparison drugs were Ofloxacin 200 mg every 12 hours for 6 months, Rifampicin 600 mg every 24 for 3 months and Isoniazid 300 mg every 24 hours for 3 months. The results, were clinically and microbiologically good. It is concluded that this new drug should be a valid alternative to the traditional therapy.

[Primary abscess of the psoas].

We present in this paper a series of cases from our Service of primary abscesses in psoas. We consider the appearance of immunosuppressed patients as a relevant factor of its etiopathogenicity. We believe that a C.A.T. is the best diagnostic method. All three patients that underwent open surgery have had complications. The patients treated with percutaneous puncture has shown a favourable evolution.
