    ABSTRACT: Life expectancy after transplantation has improved, and cancer may soon be the leading cause of late death after transplantation. The guidelines of the American and European societies of nephrology and urology have not yet established the optimal frequency for screening for renal cell carcinoma (RCC) of native kidneys in patients who have undergone renal transplantation. To evaluate the prevalence, prognosis, and risk factors of RCC in a series of patients followed up for 16 years in our transplantation unit. Our study is a follow-up observational cohort study conducted in 694 consecutive renal transplant recipients admitted to our institution from July 1991 through July 2007. At our institution, ultrasound studies of the native kidneys were performed every 6 months after renal transplantation. In the patient cohort studied, 10 patients developed a renal tumor (1.6% incidence). Three patients died of causes other than recurrence of RCC. Seven patients are alive with no evidence of RCC recurrence or metastatic disease after a mean (range) follow-up of 41 (12-96) months. Acquired cystic kidney disease and dialysis duration were positively associated with development of RCC. The incidence of RCC in the literature varies between 0.3% and 4.8%. The variability depends on the timing of follow-up, with a higher incidence in prospective studies with strict follow-up. We advise ultrasound studies performed by specialized physicians every 6 months after transplantation. More detailed guidelines designed by the major international transplantation societies are necessary.

    ABSTRACT: No data are available on incisional hernia in renal transplant recipients using a midline incision. This study evaluated the incidence of abdominal wall incisional hernia, comparing two surgical approaches: midline and J-shaped incisions. Between 1991 and 2005, 415 consecutive patients underwent renal transplantation: between 1991 and 1997, 139 patients through a lateral incision; between 1997 and 2005, 137 of 276 renal transplant patients via a midline incision, and 139 via a J-shaped incision. We evaluated the incidence of incisional herniae in these patients. Analyzed factor risks included: age, sex, body mass index, diabetes, reoperation, lymphocele, dialysis time, underlying renal disease, and immunosuppressive therapy. During follow-up, 15 patients of 415 transplantations were dead or lost to follow-up. Incisional herniae were identified in 12 cases of 132 (9%) between 1991 and 1997. Between 1997 and 2005 we identified 3 of 133 (2.2%) patients who underwent a midline incision and 15 of 135 (11.1%) who received a J-shaped incision (P=.005). Comparing midline and J-shaped incisions before and after 1997, the incidence reduction was significant (P=.01). Comparing the incidence among patients treated with J-shaped incision before versus after 1997, the increased incidence was insignificant (P=.6). Multivariate analysis found the most important risk factor was obesity followed by polycystic kidney disease, reoperation, wound infection, and mycophenolate mofetil therapy. Our data showed an advantage of a midline incision. Strategies to prevent surgical complications, such as abdominal wall relaxation and poor cosmetic results, are needed; the midline incision may be a possible alternative to address this complication.

    ABSTRACT: The study presents an original uterus sparing technique for transvaginal repair of total genitourinary prolapse. The technique employs a synthetic mesh of mixed polypropylene and 910 polyglactin fibers. The prosthesis creates a support for the cystocele, the cervix and the enterocele. It has four anchoring sites: two at the rear in the sacrospinous ligaments and two at the front in the arcus tendineous of the levator ani muscle. Between February 2001 and December 2004, 24 patients (mean age 66.9 years), presenting symptoms of uterine prolapse, cystocele and enterocele (POP-Q stage III-IV Aa associated to II-III-IV C), were treated with our procedure. Pre- and postoperative parameters were evaluated statistically. No patient had any serious complications. The mean follow-up was 31.1 months (range 6-52). 19 patients (79.1%) have shown excellent results and have been completely cured. In 5 other cases (20.8%), the cystocele was completely cured and there was a significant improvement in the hysterocele and the enterocele. One patient required surgical treatment for postoperative stress incontinence. Statistical analysis of data regarding the pre- and postoperative prolapse stage demonstrated a high degree of objective cure rates (p < 0.0001). While hysterectomy remains the habitual treatment for severe uterine prolapse, our technique provides a promising alternative solution. It is also significant that there were no complications of erosion or infection associated with the prosthesis.

    ABSTRACT: The incidence of urological complications after kidney transplantation varies from 3% to 14%, with a probable loss of the graft in 10% to 15% of cases and a mortality rate of up to 15%, despite improvements in prevention, diagnosis, and treatment as well as the use of new immunosuppressive therapies. Urinous fistulae, which are considered early complications of transplantation, are due to ischemic damage or necrosis generally occurring in the distal third of the ureter. Preservation of accessory arteries to the lower portion of the kidney is important, as they may constitute the blood supply of this segment of the collecting system or ureter. Their ligation may lead to necrosis and urinary fistulae. Ureteral stenosis, as late complication, is related to a pathology of the ureter itself, to infections, to abscesses, to fibrosis, and to ischemia. An early endoscopic approach permits resolution in 70% of cases. The aim of this retrospective study was to determine incidence and treatment of these complications. From 1991 to 2004 we performed 453 kidney transplantations both from cadaveric and living donors. In 199 patients we performed a transvesical ureteroneocystostomy (UNCS), and in 260, an extravesical UNCS. The nine patients who showed fistulae (1.9%) underwent surgical treatment. In eight we used a direct ureteral reimplantation, and in one, a Boari flap technique. Nephrectomy was necessary in four patients, including two who died of septic complications. In all 26 cases of ureteral stenosis (5.6%), we used an endourological approach (anterograde or retrograde), with surgical treatment afterward in 11 patients (42%) nine direct reimplants, one anastomosis to the native ureter (transplantation from a living donor), and in one case a Boari flap technique four patients who underwent surgical treatment showed progressive damage to graft function. In all patients who showed fistulae we suggest surgical review: for patients with ureteral stenosis, we suggest first an endourological approach and only when it is not successful do we consider surgical treatment.

    ABSTRACT: A double-blind, randomized, comparative study of mepartricin (SPA-S-160) and placebo was performed on 36 patients who complained of obstructive symptomatology caused by prostatic hypertrophy. Treatment was continued for 60 days at a dose of 150,000 IU/d (three capsules/d) of active substance. All patients underwent full urodynamic investigation consisting of pressure-flow studies before and after treatment. The final results of our study showed that 50% of the patients treated with mepartricin had an improvement in micturitional performance.

    ABSTRACT: Forty-three young men from the Italian army underwent urodynamic tests following the diagnosis of enuresis. Of these, 37 were included in an assessment trial to define the rationale for early anti-bacterial therapy following the test. The subjects were subdivided into two groups: one group received 500 mg Cinoxacin b.i.d. for 5 days, and the other group was not treated. The comparison of results revealed a high incidence of irritative disorders in both groups (78.9% of treated subjects and 88.9% of untreated subjects) but the most significant complications were observed in the untreated group (feveret in 27.7% and one case of septic fever). Early anti-bacterial therapy following standard urodynamic tests therefore seems to be a ration tool in urological practice.
