[Radical laparoscopic cystectomy].

Radical laparoscopic cystectomy is being adopted by most groups with proven experience in laparoscopic surgery, especially by those who have already completed the learning curves in radical laparoscopic prostatectomy. It is still considered a highly complex technique, which has not yet been mastered in many Urology Units. In this article, we review the surgical technique and available literature on this approach, with special emphasis on its indications, advantages and most frequent morbidity.

[Surgical management and complications of urinary stress incontinence: our experience in 385 patients operated on during the last 25 years].

We present the results and complications found and compared in 2 large series of patients who underwent a surgical procedure to avoid Urinary Stress Incontinence in our hospital. From january of 1994 to december of 2001 we collected 195 patients with an average age of 57.9 y we compared them with a prior series of 189 patients collected between january of 1976 and december of 1993, with an average age of 53.6. The continence rate was similar in both series (70.8% pre-94 and 74.5% post 94), slight incontinence 22.7% pre-94 and 19.2% post-94 and for complete incontinence 6.3% pre-94 and 6.2% post-94. The Burch procedure was the most common and also shows the greatest effectiveness in our trial involving 113 cases and a continence rate of 74.3% in the first series and 144 cases and 77% respectively in the second series. The most common complications were very similar in both groups: tract urinary infection (5.2% and 9% first and second group), surgical wound infection (4.2% and 2.2% respectively). We conclude that in spite of the introduction of new and useful surgical procedure (TVT, periurethal substances injection...) the greatest long term success rate still corresponds to the Burch colposuspension.

[Bladder malacoplakia with lymphatic involvement and an aggressive course].

Malacoplakia is an unusual chronical granulomatous disorder. In the urinary tract is more frequent in female, in 75 percent of cases involve the bladder. Pelvis extension of this disease is infrequent, and even less frequent is the involvement of pelvic and retroperitoneal lymph nodes. We present the second case in the literature of bladder malacoplakia with extravesical and pelvic node involvement.

[Ureteral stenosis after kidney transplantation: treatment with a self-expanding metal prosthesis].

OBJECTIVE: To determinate the efficacy in the treatment of ureteral estenoses after renal transplantation with metallic self-expandable stent. MATERIALS AND METHODS: From october of 1995 to april of 2002, 8 ureteral obstruction post renal transplantation have treated by means of implants of a metallic self-expandable stent (6 men and 2 women). The average time of pursuit was of 30 months (rank 2-53 months). In this work the severity and location of the estenosis are analysed, the method of implant of the stent, the permeability of the same one, the levels of creatinine pre and postimplant and the complications derived from the same one. RESULTS: The treatment was effective in the 100% of the patients (8/8), with an average reduction of the creatinine of 36% (rank 13.6%-59.6%). The complications were minimum and the hospital stay was short. CONCLUSIONS: In the patients with: chronic deterioration of the graft with short functional expectation, patient with high surgical risk and reestenosis after ureteral reimplantation by previous ureteral estenosis, the use of a metallic self-expandable stent, constitutes technique of election given its efficacy and low associate morbidity.

[Posterior sacral root neuromodulation in the treatment of chronic urinary dysfunction].

OBJECTIVES: To describe the effectiveness of sacral root neuromodulation in ameliorating symptoms of refractory voiding disfunction in our center. MATERIAL AND METHODS: During the period from december 1998 throught december 2001, 31 Percutaneous Nerve Evaluation (PNE) was performed to 20 patients with refractory voiding dysfunction; a sacral nerve stimulation device was implanted in 10 patients (8 female, 2 male). The median age was 49 years. Refractory voiding dysfunction included: mixed disorders (30%), idiopathic nonobstructive chronic urinary retention (20%), urgency/frequency (20%), faecal and urinary incontinence with absence of sphincter defect (20%) and frequency (10%). RESULTS: The 2 patients with frequency/urgency decreased their symptoms more than 50%, bladders were emptied without post-void residual urine in 2 patients with urinary retention, faecal and urinary incontinence in 2 patients and mixed disorders in other 3, reduced their symptoms more than 90% without residual urine. The frequency improved more than 50% in 1 patient. CONCLUSIONS: Sacral Root Neuromodulation is a successful treatment in some cases of idiopathic chronic micturition dysfunction which don't respond to pharmacotheraphy or bladder retraining. The effects of neuromodulation are long-lasting and associated morbidity is low.

[Treatment of female stress urinary incontinence with the TVT (tension-free vaginal tape) system: our experience].

INTRODUCTION: The TVT system is a new surgical procedure for female stress urinary incontinence. The object of this study is to report our initial experience with this technique. We report our results and complications too. MATERIAL AND METHODS: From April 1999 to July 2000, 23 systems TVT was implanted in our hospital. The patients were followed for a 6 to 21 month period. All the patients had stress incontinence. The mean age was 59 years. Gynaecological surgery was associated in 4 patients. One of them was excluded because a diagnosis mistake. TVT implies the implantation of a prolene tape around mid-urethra via a minimal vaginal incision. RESULTS: 17 patients (77.27%) had a significantly improved in the post-operative evaluation. The mean post-surgical stay in the hospital was 1.7 days. A bladder base was damaged during the surgery. No urinary retention, erosion or urethral lesion were found. CONCLUSIONS: We consider the TVT operation to be a safe and effective surgical procedure for the treatment of female urinary stress incontinence. This surgery is easy to lean, fast, cheap and with a low rate of complications.

[Lymphadenectomy in squamous carcinoma of the penis: review of our series].

OBJECTIVE: To analyze the series of patients who underwent inguinal lymphadenectomy in our Center due to squamous penile carcinoma, between years 1984 to 1999. MATERIAL AND METHODS: Lymphadenectomy was carried out in 19 patients, with a mean age of 61 years. Bilateral ilioinguinal (42.1%) was the most frequent type of intervention. Only four patients underwent penectomy and lymphadenectomy simultaneously. We present the clinical and pathological results, according to the 1997 TNM classification. RESULTS: Palpable inguinal nodes after antibiotherapy remained in seven out of 12 patients. The overall correlation between N and pN stages in our series was 68.42%. Pathological results according to pT and pN stages are also presented. Postoperative complications were present in 13 cases (68.42%), (lymphedema being the most frequent one). In those patients with two or less pN(+) nodes, an overall one-year and five-year survival of 90 and 80% were obtained; compared to 11.11 and 0% when there were more than two. CONCLUSIONS: The importance about control of metastatic lymph nodes in squamous carcinoma of the penis, places inguinal lymphadenectomy as an essential tool, in those suitable cases. However, its incidence of complications makes a progressive agreement about its indications be necessary.

[Comparative study of ureteral anastomosis with or without double-J catheterization in renal transplantation].

OBJECTIVE: To analyze the impact of the use of the routine double-J stent in the incidence of urological complications, like fistula, stenosis, ureteral obstruction and urinary tract infection. METHODS: A retrospective study was conducted on two groups of patients: 28 without double-J stent and 28 with it. We reviewed urological complications: stenosis, fistula and obstruction. We paid special attention to urinary tract infection and other inherents complications to the use of double-J stents. RESULTS: A patient from the double-J stended group (3.6%) developed a urinary fistula and there were no obstructions. 13 patients (46.6%) had a positive urinary culture in the first month post RT. Two urinary fistulas and 4 obstructions were developed in the non-stended group. Six major complications of the urinary tract. 14 patients (50%) had a positive urinary culture in the first month post RT. CONCLUSIONS: The use of double-J stent across uterovesical anastomosis decreases the post-RT ureteral complications. Stent placement does not increase the risk of urinary tract infection in the early post-RT.

[Hand-assisted laparoscopic nephrectomy].

INTRODUCTION AND OBJECTIVES: To present the number of cases of hand-assisted laparoscopic nephrectomy. This study evaluates our results and difficulties of starting a progresive programme of laparoscopy. MATERIAL AND METHOD: Between november 2003 and november 2005, 35 hand-assisted laparoscopic nephrectomies were carried out, of a total of 45 laparoscopic nephrectomies. 22 radical nephrectomies, 3 simple nephrectomies and 10 nephroureterectomies. The average age of patients was 66 years (47-89). On average, they were overweight (IMC 28,3), with approximately 38% being obese. ASA 2.3 (1-4). The tumors measured 4.8cm on average, and 80% of these were T1. In 28.6% of the cases, they had previously undergone abdominal surgery. RESULTS: One was undertaken in 2003, 17 in 2004, and 17 in 2005. The surgery time was 140 minutes, 130 minutes (80-210) in radical nephrectomies, 135 minutes (120-150) in simple nephrectomies and 163 minutes (80-240) in the nephroureterectomy. Patients began an oral diet 1.7 days later, and were able to get up 1.7 days later. In the case of obese patients, they began an oral diet 2.3 days later and were able to get up (2.4 days) later than those non obese cases. (1.5 and 1.4 days respectively). The average stay has been 5.8 days (3-15). The average stay of the cases without complications was 4.2 days and those that encountered complications 9.7 days. In no cases was there a need for a blood transfusion. In 11.4% we had major complications with an average stay of 11.7 days. In 5.7% of cases there were reconversions, and 5.7% of cases were reoperated. 17.1% had minor complications, with an average stay of 8.8 days CONCLUSIONS: The advantage of hand-assisted nephrectomy is that it allows one to begin a laparoscopy, with a reduced learning time, and with satisfactory results, allowing the incorporation of laparoscopy surgery in hospitals with a reduced annual volume.
