The aim of this study was to establish the prevalence of Y chromosomal microdeletions in infertile Tunisian men. Three groups of infertile men, 65 normospermic, 53 oligozoospermic and 45 azoospermic, were tested for Yq microdeletions detection by multiplex polymerase chain reaction (PCR) using specific Y chromosome AZF regions tagged site markers (STS). One group of 13 healthy men was used as the control group. Six STS were tested (2 in each AZF region). The general prevalence of AZF microdeletions was 16%; in azoospermia and severe oligospermia groups, it was higher (29% and 30.5%, respectively). Significant differences were found with moderate oligospermic and normospermic groups (p [ABSTRACT FROM AUTHOR]

Objective: To evaluate the influence of continent external urinary diversion type Mitrofanoff on male sexuality., Material and Methods: Between 1992 and 2011, 140 patients underwent continent urinary diversion type Mitrofanoff at an academic hospital. Among 76 men, 46 were interviewed about their sexuality after this operation. This study was performed using a set of validated questionnaires (IIEF, DAN PSS and Urolife), grouped by the model of the CTMH. Patients were divided according to their marital status: group 1: patients married before surgery (15 cases), group 2: patients married after surgery (7 cases) and group 3: singles (24 cases)., Results: In the first group, the functional dimension of sexuality was positive with an overall score of 81%, the sexual discomfort score was assessed at 26 % and the sexual satisfaction score was 77%. In the second group, sexual function was considered conserved in all cases with a satisfaction score estimated at 98%. These patients reported a feeling of well-being following the disappearance of urinary incontinence with integrity of their body images. In contrast, in the last group, relatively impaired sexual function was noted (65%) with a satisfaction score estimated at 59%. These disorders were multifactorial, mainly related to neurological causal pathology., Conclusion: To our knowledge, this is the first study about male sexuality in patients with a continent urinary diversion type Mitrofanoff. Marital status has a major role in the sexuality of these patients. A prospective study with pre- and postoperative evaluation will better clarify the factors affecting sexuality in these patients., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

We report a nosocomial outbreak of urinary tract infection caused by Myroides odoratimimus, previously called Flavobacterium odoratum, in the urology unit of a Tunisian hospital. From May to November 2010, seven isolates of M. odoratimimus were recovered from urine. Pulsed-field gel electrophoresis clearly differentiated these isolates into two possibly related clones from two different periods. All patients but one had urinary calculi and underwent endourological surgery. All Myroides isolates were resistant to all antibiotics tested. Three patients were successfully treated with ciprofloxacin and rifampicin. Clinicians should be aware that M. odoratimimus may induce serious and prolonged nosocomial outbreaks of urinary tract infections., (Copyright © 2011 The Healthcare Infection Society.

Introduction: We compared short- and long-term outcomes of renal transplants with single versus multiple arteries., Patients and Methods: We retrospectively analyzed data from kidney transplants from 208 living donors performed between 1994 and 2010. Renal grafts were divided into two groups: single renal artery (n = 164) versus multiple renal arteries (n = 44). The groups were compared regarding early and late vascular and urological complications. Patient and graft survivals were compared using Kaplan-Meier survivorship curves with comparisons using the log-rank test., Results: Both groups were comparable regarding acute rejection episodes, posttransplant hypertension, postsurgery renal artery stenosis, and urologic complications. Only hemorrhagic complications and renal artery thrombosis were significantly higher in the multiple renal arteries group (P = .027 and .03, respectively). Warm ischemia time was significantly longer in the multiple renal arteries group without any influence on the incidence of acute tubular necrosis (P = .2). Mean creatinine clearance at 1 year was 65 versus 50 mL/min/1.73 m(2) (P = .5) and at 5 years, 60 versus 55 mL/min/1.73 m(2) (P = .1) for the single versus multiple renal arteries groups, respectively. Return to hemodialysis was necessary for 18.8% of the single and 16.1% of the multiple renal arteries group., Conclusion: The use of an allograft with multiple renal arteries is a safe, successful surgical procedure, that does not influence patient or graft survivals or increase surgical complication rates provided the surgical team is evolved with technical skill., (Copyright © 2011 Elsevier Inc.

De novo tumors are common complications after solid organ transplantation. Lymphoma and skin cancers are the most frequently observed malignancies. However, graft carcinomas can be observed to be five times more frequent after kidney transplantation compared to their incidence in the general population. We report a case of a 49-year-old female who developed an early adenocarcinoma of the graft as revealed by acute renal failure. She underwent transplantectomy and chemotherapy with hemodialysis therapy. Carcinoma of the graft is a rare but serious complication usually occurring late after transplantation. Close monitoring of a kidney recipient using abdominal ultrasound may detect this complication at early stages, which may improve the prognosis. Similarly, good screening of donors may prevent tumor transmission., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Objective: To study the evolution of impaired renal function after external continent urinary diversion (Mitrofanoff principle) (ECUD-M) associated with ileocystoplasty., Patients and Methods: Over 18 years from 1992 to 2009, ECUD-M with ileocystoplasty was performed in 120 patients with mean age of 25.5 years. Renal impairment was evident in 43 patients (17 children and 26 adults)., Results: Ninety percent of patients demonstrated a neurologic bladder and mild to moderate renal failure. Initially, all patients underwent continuous bladder drainage for a mean of 3 weeks. Renal function improved in 35 patients, although with persistent mild renal insufficiency. The other patients demonstrated moderate persistent residual renal insufficiency. During a mean follow-up of 10 years (range, 1-18 years), renal function returned to normal in 13 patients, stabilized at lower values in 15, and remained moderate in 5. After a mean follow-up of 8 years (range, 6-12 years), renal failure gradually worsened, increasing to higher values in 6 patients and leading to hemodialysis in 4. One patient underwent living-donor kidney transplantation, with good evolution., Conclusion: ECUD-M with ileocystoplasty can lead to normalization unless stabilizationof impaired residual renal function by eliminating the obstructive factor provides self-adequate management of the diversion. The procedure delays for the need forhemodialysis therapy, and enables patients to prepare for kidney transplantation into a previously reconstructed lower urinary tract., (Copyright © 2011 Elsevier Inc.

Purpose: To assess the effect of varicocelectomy in sperm quality and natural pregnancy and to determine if it can change couple candidacy for assisted reproductive technology (ART) procedures., Materials and Methods: We performed a retrospective study about 164 infertile men with varicocele associated to sperm abnormalities. We divided our patients into four groups, according to the total motile sperm count (TMC). Group 1 includes 21 azoospermic men, group 2 includes 62 patients who had a TMC strictly less than 1.5x10(6), group 3 includes 22 patients who had a TMC between 1.5 and 5x10(6) and group 4 includes 59 patients who had a TMC strictly greater than 5x10(6). All patients underwent surgical or percutaneous embolisation to repair varicocele., Results: After treatment, the mean spermatozoid concentration and motility were significantly increased, respectively from 24.8 to 29.2x10(6)spermatozoids per millilitre and 14.4 to 23.2%. Spontaneous pregnancy was observed in 59 couples (35.9%). Concerning the couples who had no pregnancies (105), 51 (48.5%) showed increase of the TMC, which allowed them to change the foreseen preoperative ART by an other one more simple., Conclusion: Varicocelectomy has a significant potential not only to improve sperm quality and natural pregnancy, but also to downstage the level of ART needed to male infertility management.

Objective: To analyze the urodynamic parameters and the mechanisms of continence of Mitrofanoff urinary diversion., Material and Methods: Urodynamic assessment was performed via the stoma in 11 patients with continent urinary diversion according to the Mitrofanoff principle. The mean age of the patients at the time of the operation was 29 years. The appendix, used as conduit in all cases, was anastomosed to the skin of the right iliac fossa. Ileocystoplasty was performed in 10 patients. The urodynamic assessment was performed after a mean follow-up of seven years (range: five to 12 years)., Results: Reservoir pressures after filling did not exceed 20 cm H2O in nine cases. Uninhibited contractions were recorded in two patients with an enlarged bladder with pressures not exceeding 30 cm H2O. Appendix pressures during filling were always higher than bladder pressures. The mean pressure measured at the end of filling was 75 cm H2O (range: 45 to 90 cm H2O). After the Valsalva maneuver, these pressures were between 80 and 150 cm H2O with good transmission. The mean conduit closing pressure was 70 cm H2O (range: 40 to 90 cm H2O). The mean functional length of the conduit was 5 cm (range: 2.6 to 7.2 cm)., Conclusion: The Mitrofanoff diversion is mainly characterized by the high intraluminal pressure in the continent conduit. A low bladder pressure is essential to maintain a perfectly continent diversion.

Post traumatic renal artery thrombosis is rarely described in the literature. This pathology can result from stretch injury to inelastic intima of the renal artery, or by the direct flow to the abdomen causing compression injury to the renal artery against the vertebral column. However, the association of this pathology with hematologic diseases (in particular protein C deficit) was never described. We report an observation of a 28-year-old man with an uneventful history who was admitted to the intensive care unit for traumatic head injury associated with post traumatic renal artery thrombosis requiring nephrectomy. The etiologic investigation of this thrombo-embolic complication reveals a protein C deficit. Our patient was improved under treatment. This original observation confirms that post traumatic renal artery thrombosis can be associated with hematologic diseases (in particular protein C deficit).

The verrucous carcinoma is an unusual shape of well differentiated squamous cell carcinoma, first described at the ORL region; the kidney location is rare; the risk factors are represented essentially by lithiasis and/or urinary infection; the clinical symptom is not specific. Diagnosis is facilitated by radiological investigations and particularly excretory urogram/ultrasound; certainly diagnosis is pathological. The nephro-ureterectomy with collar resection of the bladder is the choice treatment. We report two observations and we clarify clinicopathological aspects of this type of carcinoma and we discuss the prognosis.

The authors report six cases of primary malignant paratesticular tumors. They reexamine the literature and emphasize the influence of the histopathological type of these tumors on the prognosis. Survival of the patients is better when tumors are differentiated and detected early.

The authors have made a study of 6 cases of malignant primary paratesticular tumor, and have also included a review of the literature on this topic. They emphasize the importance of the effect of histopathological type of tumor on disease outcome. There is an improved survival potential in cases where the tumors are differentiated, and discovered at an early date.

Carcinosarcoma of the urinary bladder is a uncommon tumor with characteristic histopathologic and immunohistochemical findings; his histogenesis have still not been clear; the prognosis seems to be improved by radical cystectomy and adjuvants therapies. We report a case of 47 years old women suffering from suprapubic pains, dysuria and hematuria of five months duration and had a 10 cm suprapubic mass that was found on physical examination. Radiographically, the tumor invaded the dome of the urinary bladder and causes bilateral hydronephrosis. Microscopically it was an urinary bladder carcinosarcoma. Our objective is to discuss the histogenesis, the anatomoclinical and prognosis of these rare tumors.

The prostatic utricle is a small vestigial diverticulum on the posterior surface of the prostatic urethra. It is considered to be pathological when it is abnormally dilated. The prostatic utricle is revealed by signs of vesical irritation and dysuria, sometimes associated with a retrovesical mass on examination. The authors report two cases of pathological prostatic utricle. The first case was an 11-year-old boy presenting with dysuria. Retrograde cystourethrography confirmed the diagnosis. The utricle was resected via a transtrigonal intravesical approach. The second case was a 25-year-old man who presented with dysuria associated with a pelvic mass. IVU and ultrasonography suggested a diagnosis of retrovesical cyst. This patient underwent incomplete resection of the utricle via a retrovesical approach. Based on a review of the literature, the authors emphasize the need to look for a prostatic utricle in a young subject presenting with dysuria, particularly in patients with a malformation of the genitourinary tract (hypospadias, renal agenesis). All pathological prostatic utricles must be treated surgically. The incision is transtrigonal in medium-sized utricles and transperitoneal in large utricles. The utricular cavity must be resected as completely as possible.

The authors report 64 renal cell carcinomas observed in 64 patients over a period of 14 years (1982-1995). The mean age was 58 years (range: 20 to 80 years). Male involvement was observed in 34 cases (53%). The clinical symptoms were nonspecific, consisting of haematuria (26 cases), back pain (33 cases) and tumour (8 cases). Twenty patients presented with paraneoplastic syndromes and 4 presented with metastases. The tumour was an incidental finding in 6 cases. Fifty two patients were treated by radical nephrectomy and two by partial nephrectomy. The tumour was associated with venous involvement in 2 cases, lymphatic involvement in 4 cases and distant metastases in 2 cases. The overall 5-year survival was 37% with a poor prognosis in the case of lymph node involvement or metastases and in the case of secondary local recurrence (4 cases) or distant metastases (2 cases).

The authors report a retrospective series of 45 cases of blunt renal trauma from a total of 685 cases of blunt abdominal trauma observed between 1989-1993. This multicentre trial was designed to illustrate the severity of this type of trauma and to place it in the context of road accidents in Tunisia.

The authors report a retrospective study of 34 cases of blunt renal trauma affecting a pathological kidney out of a total of 156 cases of renal trauma. The patients were between the ages of 3 and 60 years, with a male predominance (sex-ratio: 2.4). The predominant cause of trauma was a household accident, in 15 cases (44%). The clinical features were dominated by haematuria and pain. The underlying renal disease was dominated by renal stones (15 cases, 44%) and ureteropelvic junction (UPJ) abnormality (10 cases, 29%). Twelve patients with benign trauma and minimal underlying renal disease were treated conservatively. Surgery was indicated in the remaining 22 patients, but only 20 were actually operated. Nephrectomy was performed in 9 patients and partial nephrectomy was performed in 3 patients. Treatment consisted of UPJ plasty in 2 cases, uretero-caliceal anastomosis in one case, stone surgery in 4 cases and suture of ruptured renal pelvis in one case. The postoperative course was marked by the development of a urinary fistula in 1 patient, cured by drainage and deterioration of hydronephrosis in one patient. Lastly, one patient died from Wilms' tumour. This disease therefore tends to have a fairly benign course, which nevertheless depends on the underlying renal disease.

The authors report a retrospective series of 18 cases of rupture of the anterior urethra, with a mean age of 25 years (range: 10 to 45 years). The mechanism of the lesion was trauma by falling onto the perineum (12 cases), road accident (4 cases) and sexual intercourse (2 cases). Urine drainage was ensured by suprapubic catheter (15 cases) or urethral catheter (1 case). The two cases of rupture of the urethra associated with lesions of the corpora cavernosa required urgent surgical repair. In the other cases, simple urine drainage was sufficient to treat partial ruptures of the urethra (11 cases) with only one case of urethral structure. However, end-to-end urethrorraphy was performed in the 4 patients with total rupture of the urethra, with early failure in 3 cases, attributed to delayed surgery. Finally, the course of urethral rupture associated with rupture of the corpora, cavernosa was favourable in terms of both micturition and sexual function.

The authors report a retrospective series of 65 cases of renal contusion in children affecting 45 boys and 20 girls between the ages of 10 months and 15 years (mean age: 10 years). The causes of renal trauma were dominated by household accidents (53.8%) and road accidents (33.8%). Associated extrarenal lesions were observed in 21.5% of cases. 55.4% of the 65 contusions were considered to be benign, 27.7% of moderate severity and 16.9% were serious. The blunt trauma affected a pathological kidney in 19 cases. Exclusively medical treatment was recommended in 31 patients, while surgery was indicated in the other 34 patients. Apart from one death in a context of multiple trauma, few complications were observed in the group of operated patients and consisted of 4 cases of urinary fistula and 4 cases of infection, all of which resolved.

The authors report a case of bladder hernia associated to prostatic benign hyperplasia. The diagnosis is confirmed by intra-venous urogram and computed tomography imaging. The reintegration of the bladder in the abdomen was performed in association to endoscopic resection of the prostate. Bladder hernia is rare condition. Surgical treatment of bladder hernia is associated to the etiology (prostatic benign hyperplasia...) of the hernia to prevent recurrence.

The authors report 5 cases of bladder herniation through inguinal ring. All the patients were males aged between 52 and 72 years with a mean of 63 years. The clinic symptoms were non specific. In four cases the diagnosis was made by IVP. In the fifth case the bladder herniation was discovered after an incidental opening of the bladder during a right inguinal hernia repair. Four patients were operated on for replacement of the bladder and repair of the hernial ring; the procedure followed was Mac Vay technique in two cases, Shouldice in one case and placement of a Mersuture prosthesis in another case. The fifth patient was operated on because of major constraint related to his general conditions. Results was quite satisfactory in all operated cases with a mean control of 24 months.

Retention of infected urine in the upper urinary tract which is due to obstruction is a serious condition during pregnancy. The authors report their experience on five cases and propose attitudes to adopt against such emergency. Ultrasounds allow accurate diagnosis of the obstruction and may be helpful to find its etiology. Plain X ray film could be of interest mainly for stone recognition after the third month of gestation. Surgical treatment, when possible allows either relief of obstruction and cure of the original disease, otherwise performance of percutaneous nephrostomy represents a better way of drainage until the end of pregnancy.

The authors report 6 cases of adrenal pheochromocytoma seen over a period of 3 years (1993-1995). All patients were females, aged between 17 and 43 years with a mean of 35 years. Clinical manifestations consisted of either sustained hypertension, with episodes of hypersudation and palpitations, or paroxysmal hypertension which was revealed during surgery ; the disease was sometimes discovered incidentally. C.T and ultrasound showed in every cases adrenal mass as 3 to 6 cm usually located on the left side (5 cases). All patients were operated via lumbotomy and adrenalectomy was performed. In one case an associated thrombus within the vena cava was removed. Postoperative follow-up was uneventful except for one patient who developed a recurrent episode of hypertension.

The authors report 20 cases of adrenal cortex tumours which were collected over a period of 12 years (1984-1995). Sixty five per cent of patients were females. They were aged between 27 months and 85 years with a mean of 40 years. Clinical symptoms were dominated by hypertension (11 cases). Seven cases were discovered incidentally and a precocious puberty syndrome presented in the form of 2 cases. Surgery was performed in 18 cases. Adrenalectomy was performed in 16 cases and tumor removal in 2 others. Four patients underwent other procedures such as nephrectomy or splenectomy. Three adrenal tumors were considered to be malignant. Postoperative follow-up was marked by two deaths; otherwise the postoperative course was uneventful.

The authors report a retrospective series of 174 patients with urolithiasis. They were all age between 65 and 88 years. This group represents one tenth of all patients treated for urinary stones in the Urology department of Sfax over the last decade. Neither the clinical symptoms nor radiological findings observed in this group differed from those other patients hospitalized for urolithiasis; on the other hand associated diseases related to aging appear to be well represented which alters the management, prognosis and outcome in this type of patients.

Five cases of cancer of the testicle in patients with cryptorchidism are presented. In one case the tumour occurred 16 years after cure for cryptorchidism at 15 years of age. In the other cases, the tumour developed on a testicle in an inguinal or intra-abdominal position. In two cases, it was impossible to remove the tumour which had developed on an intra-abdominal position. These patients died. These cases emphasize the importance of surgical cure in all cases of cryptorchidism, preferable before the age of 2 years, in order to improve functional prognosis and reduce the risk of cancerization. The gravity of cancer of the testicle in cases of cryptorchidism is often discovered too late.

The incidence of impotence increases with age. Its etiology is always complex and often multifactorial. The hidden organic causes of impotence are as follows in decreasing order of frequency: arterial, venous, neurological and endocrine. Paraclinical investigation of erection dysfunction plays an important role: hormone levels, arterial Doppler, digitalised rigidimetry, the intracavernous test, cavernometry-cavernography and internal iliac angiography, are used to define the diagnosis and determine appropriate management. It is stressed that supportive sex therapy is often indispensable and that penile prostheses are the final recourse, when treatment based upon etiology has failed.

The authors report their experience of the use of the Lithoclast in endocorporeal lithotripsy in 19 patients. This modality allowed the fragmentation of 24 renal stones and 14 ureteric stones with complete success in 58% of cases and partial success in 42% of cases. No failures of stone fragmentation were observed in this series with the Lithoclast. The authors consider this apparatus to be an effective and inexpensive method of endocorporeal lithotripsy for all types of urinary stones.

The authors report 3 cases of penile carcinoma seen over a 15 year period. They analyse features related to epidemiology, etiopathogeny, diagnosis and treatment, and review the literature on this affection.
