[A case of hepatitis C virus possible transmission following a transrectal ultrasound guided prostate biopsy]. / Un cas de possible transmission du virus de l'hépatite C au décours d'une biopsie transrectale échoguidée de prostate.

The prostate biopsy is a current and well-codified act. To date, there have been no reported risks of viral transmission between patients linked to contaminated ultrasound probe. We report the case of a patient having contracted the virus of hepatitis C after transrectal prostate biopsy during an individual screening of prostate cancer.

[Torsion of spermatic cord: can we trust a previous orchidopexy? A case report with loss of a single testis with medico-legal issue]. / Torsion du cordon spermatique: faut-il faire confiance à un antécédent d'orchidopexie? À propos d'un cas ayant entraîné la perte d'un testicule unique avec conséquences médicolégales.

The authors report the case of a patient aged of 27 years who presented in the past a testicular torsion with loss of the ipsilateral testis and fixation of the contralateral one. Ten years later, he presented with pain on the remaining testis, which evolved to necrosis, and led to a second orchidectomy. In retrospective, it appears that the assumption that the testis had been adequately fixed ten years earlier led to the loss of the remaining testis. We thus recommend an urgent surgical exploration when facing a suspicion of spermatic cord torsion, regardless of previous history of orchidopexy.

[Pathophysiology and management of Peyronie's disease in adult patients: an update]. / Physiopathologie et prise en charge de la maladie de La Peyronie.

Peyronie's disease (PD) is due to a fibrotic plaque forms in the tunica albuginea layer of the penis. It is responsible of penile pain, angulation, and erectile dysfunction. Even though the aetiology remains unknown, the knowledge of the pathophysiology has evolved in recent years. Recent studies indicate that PD has prevalence of 3 to 9% in adult men. During the initial acute phase (6 to 18 months), the condition may progress, stabilize or regress in 20%. Therefore, a conservative treatment approach has been advocated. An initial discussion about evaluation, information, and reassurance is necessary in most cases. The most commonly employed oral therapies include tocopherol (vitamin E), and para-aminobenzoate (Potaba), which have failed to demonstrate efficiency. Intralesional injection therapies with interferon alpha-2B, verapamil are frequently used as a first-line treatment modality, and can provide an improvement in decreasing penile pain and penile curvature. Current literature has shown that extracorporeal shock wave lithotripsy was only active on the pain. Regarding penile curvature, there are discrepancies in the published series. The surgical approach is restricted to men unresponsive to nonoperative therapies (i.e., 10% of patients). In such cases, plication, grafting or even penile prosthesis implantation are conceivable management options.

[Technical aspects of laparoscopic robot-assisted pyeloplasty]. / Aspects techniques de la pyéloplastie laparoscopique robot-assistée.

From 2000, the robot-assisted laparoscopic approach has been developed for the management of ureteropelvic junction obstruction (UJO) with equivalent outcomes to conventional laparoscopic access regarding functional results. This system has simplified the suturing and has improved the precision of operative technique. The main surgical steps of the transperitoneal laparoscopic robot-assisted pyeloplasty are as follows: four or five port arrangement; initial dissection and early identification of the ureteropelvic junction; renal pelvis section; transection of the ureter and preparation of a spatula; continuous posterior suture; confection of a handle racket suture; placement of a double J stent; ending of the anastomosis. Outcomes after robotic and pure laparoscopic pyeloplasties are equivalent nowadays. Despite the financial cost, it seems easier and technically feasible and accessible for surgeons accustomed to the laparoscopic techniques and even beginners to learn the robotic technique if the system is available in their institution with success rate (radiologic and clinical) almost similar with those obtain with open techniques.

[Etiology and management of erectile dysfunction in patients with diabetes mellitus]. / Etiologie et prise en charge de la dysfonction érectile chez le patient diabétique.

Prevalence of erectile dysfunction (ED) has a higher incidence in patients treated for diabetes mellitus as it concerns more than 30% of them. ED's physiopathology is complex and multifactorial, involving a combination of classical risk factors (endothelial dysfunction), specific factors (e.g., diabetic neuropathy) and psychological factors. ED is most often forewarning a cardiovascular disease. Therefore, it needs to be detected by the physician who is taking care of the diabetic patient. ED is responsible for a deterioration of the quality of life. Therapeutic management relies, on one hand, on specific measures such as prevention of diabetic complications and, on the other hand, on psychological accompaniment of the patient. Phosphodiesterase-5 inhibitors have become the first-line treatment as they are efficient and safe in most cases. As a second line, intracavernous injections remain a gold-standard treatment but the vacuum can be proposed as well. In case of failure, penile prosthesis can even be considered. The psychological dimension of ED has to be considered as much as organic matters.

[Oncologic and functional outcomes after robot-assisted laparoscopic radical prostatectomy]. / Résultats carcinologiques et fonctionnels de la prostatectomie totale laparoscopique robot-assistée.

The current gold standard treatment for localized prostate cancer remains open radical prostatectomy. From 1992, several teams have tried to explore less invasive surgical access. The first robotically assisted laparoscopic prostatectomy (RALP) case was reported in 2000. Enhancement of the ergonomics and optimization of the surgical vision provided by the robotic interface, are some reasons that explain the worldwide widespread of RALP. Although this procedure accounted for the vast majority of radical prostatectomies performed in United States, its diffusion is still limited in Europe. The cost for robot purchase and maintenance are obvious limiting factors for its expansion. According to the literature, the operating time and the blood loss are, once the learning curve is completed, similar to those of open or laparoscopic procedures. Hospital stay and time before bladder catheter removal are shorter compared to other approaches. Intermediate oncological and functional outcomes do not show difference with the open or laparoscopic results. Given that these data are encouraging, the limited follow-up with RALP do not allow to draw any definitive statement in comparison with conventional techniques.

Age as only predictive factor for successful sperm recovery in patients with Klinefelter's syndrome.

The study was performed to determine factors affecting successful sperm retrieval by testicular sperm extraction in patients with nonmosaic Klinefelter's syndrome (KS). From May 2001 to February 2007, 27 azoospermic patients were diagnosed as having nonmosaic KS. All patients underwent sperm testicular extraction. Patient's age, testicular volume, serum follicle-stimulating hormone (FSH) and inhibin B were assessed as predictive factors for successful sperm recovery. Of the 27 Klinefelter's patients examined, eight (29.6%) had successful sperm recovery. The comparisons of serum FSH, inhibin B and testicular volume between patients with and without successful sperm retrieval did not show any statistical significance. The patients with successful sperm recovery were significantly younger (28.6 +/- 3.11 years) than those with failed attempts (33.9 +/- 4.5 years, P = 0.002). The rate of positive sperm retrieval was significantly higher in patients younger than 32 years compared with patients older than 32 years (P = 0.01, chi-squared test). The study showed that clinical parameters such as FSH, inhibin B and testicular volume do not have predictive value for sperm recovery in patients with KS. The mean age of our patients with successful sperm recovery was significantly lower than that of men with unsuccessful results. Testicular sperm extraction or testicular sperm aspiration should be performed before the critical age of 32 years.

[Erectile dysfunction and renal chronic insufficiency: etiology and management]. / Etiologie et prise en charge de la dysfonction érectile chez l'insuffisant rénal chronique.

Erectile dysfunction (ED) has a higher incidence in patients treated for chronic renal insufficiency or in patients who underwent kidney transplanation as it concerns more than 50% of them. Its severity is directly linked with the seriousness of the renal disease. ED is responsible of a deterioration of the quality of life. ED's physiopathology is complex and multifactorial, involving a combination of classical risk factors (endothelial dysfunction), specific factors (e.g., chronic hyperuremia and co-morbidities) and psychological factors. Management of ED must take into account both sides of the disease in order to propose appropriate treatment; i.e, psychological concerns and organic matters. Although literature remains poor in this area, phosphodiesterase-5 inhibitors are increasingly used for these patients as they are safe and efficient most of the time. Pharmacokinetics of phosphodiesterase-5 inhibitors can be disturbed by the simultaneous use of immunosuppressor. As a second line, intra-cavernous injections remain a gold-standard treatment. In case of failure, penile prosthesis can even be considered in case of renal chronic insufficiency and in transplanted patients.

[Combined liver-kidney transplantation: indications and results]. / Transplantation foie-rein combinée: indications et résultats.

PURPOSE: The purpose of this article is to report our experience concerning the indications and results for combined liver-kidney transplantation in our centre. MATERIAL AND METHOD: From July 1991 to October 2006, 26 patients underwent combined liver-kidney transplantation in our establishment. This group comprised 16 men and 10 women with a mean age of 50.1 years (range: 19 to 68 years). The main indications were as follows: hepatorenal polycystic disease, type I hyperoxaluria, cirrhosis associated with end-stage renal failure. RESULT: The median follow-up was 62.73 (+/-50.9) months. Only two patients of this series died, one at 70 months from gastric cancer, and the other at 89 months from cerebral metastases. Nine patients developed surgical complications (29%). Liver function was normal in the 24 surviving patients. Only one case of loss of renal graft was observed at 12 years and this patient is currently on dialysis. The mean creatinine level in these patients (apart from the dialysed patient) at the last follow-up visit was 120.3 (+/-30.43)micromol/l. CONCLUSION: Combined liver-kidney transplantation can be performed with acceptable morbidity and mortality and excellent long-term results.

[Results of sacral posterior neuromodulation on voiding disorders and impact on sexuality based on a single-center study]. / Résultats de la neuromodulation des racines sacrées postérieures sur les troubles mictionnels et impact sur la sexualité à partir d'une étude monocentrique.

OBJECTIVE: The objective of this study was to evaluate the results of S3 sacral neuromodulation on certain voiding disorders (overactive bladder and chronic retention) and its impact on the sexuality of these patients. MATERIAL AND METHOD: A S3 sacral root neuromodulator was implanted in 41 patients with a mean of age of 53 years between January 1999 and March 2004. This study comprised two groups: one group composed of patients with overactive bladder (32 subjects) and the other composed of patients with chronic retention without obstruction (nine subjects). RESULTS: The mean follow-up of this study was 34 months (range: 12 to 72 months). In the group of patients with overactive bladder, after the operation, the daily voiding frequency decreased from 20.8 to 7.8 (p<0.0001), episodes of incontinence decreased from 3.7 to 1.4 per day (p<0.0001), the number of pads decreased from 2.5 to 1 per day (p<0.001) and 72% of these patients reported an improvement of their continence time. In the group with chronic retention, the number of intermittent self-catheterizations decreased from 4.77 to 0.44 per day (p=0.0169) and 72% of these patients resumed spontaneous voiding (7/9). Among this patient population, 41.5% reported sexual problems, which were improved after implantation of the neurostimulator in 41.2% of cases. CONCLUSION: In the light of these results, sacral neuromodulation appears to be an effective treatment for certain refractory chronic voiding disorders such as overactive bladder and chronic retention without obstructive syndrome. This study showed that improvement of clinical signs could have a positive impact on the sexuality of these patients, especially for patients with chronic retention without obstruction.
