The effect of transurethral resection of the prostate (TURP) on erectile function is still controversial, and available evidence is conflicting. One of the possible mechanisms of post-TURP erectile dysfunction (ED) is direct thermal injury to the erectile nerves. The aim of this study was to investigate the effect of TURP on erectile function. Fifty patients undergoing TURP for obstructive benign prostatic hyperplasia (HBP) were prospectively included in the study, and 50 age-matched patients undergoing transurethral resection of the superficial bladder tumor were also prospectively included as a control group. All patients completed the international index of erectile function (IIEF-15), the international prostatic symptom score (IPSS) and the Hospital Anxiety and Depression Scale at inclusion in the study and then at the 3-and 6-month follow-up evaluation. Capsular perforations during TURP were prospectively reported by the operating surgeon. There was a significant improvement of erectile function in the TURP group despite the onset of ejaculation disorders in 70% of the patients. Improvement of erectile function was also found in the subgroup of patients with capsular perforation during TURP. Comparison with the control group showed that at preoperative evaluation, patients in the TURP group had more severe urinary symptoms and worse erectile function than did those of the control group. At the postoperative period, the IPSS score became comparable in the two groups, with major improvement of erectile function in the TURP group. We concluded that TURP improved erectile function in HBP patients with severe urinary symptoms. This improvement of erectile function was observed even in case of capsular perforation.

Isolated renal vein thrombosis is a rare entity. We present a patient whose complaint of flank pain led to the diagnosis of a renal vein thrombosis. In this case, abdominal computed tomography angiography was helpful in diagnosing the nutcracker syndrome complicated by the renal vein thrombosis. Anticoagulation was started and three weeks later, CTA showed complete disappearance of the renal vein thrombosis. To treat the Nutcracker syndrome, we proposed left renal vein transposition that the patient consented to.

IntroductionRenal infarct is rare and often misdiagnosed because the symptoms are misleading. The mechanisms are various, mainly thrombotic and embolic.Case presentationIn this review, we report the case of a 61-year-old Tunisian woman presented to the emergency unit with a 4-hour history of abdominal pain diffused at both flanks, ultrasounds was performed to remove a surgical emergency, showed a peri-renal fluid collection with heterogeneous parenchyma.We followed by a CT scan, which confirmed the diagnosis of renal infarct. The patient was treated by heparin at a curative dose, and the outcome was favorable.ConclusionDiagnosis is difficult and should be considered in patients with inexplicable flank or abdominal pain and with risk factors to this disease. Our purpose is to raise clinician’s awareness for this condition so that they will be more likely to diagnose it. This will facilitate prompt diagnosis and treatment.A review of the literature was performed and the case is discussed in the context of the current knowledge of this condition.

Purpose Penile skin flap uretroplasty is a useful technique for a long urethral stricture due to the ample length and surgical handling characteristics. We investigated the surgical technique and initial results of uretroplasty for anterior urethral strictures using a dorsal penile skin flap.Patients and methods From January 2003 to January 2018, a total of 77 patients underwent substitution urethroplasty using dorsal penile skin flap for bulbar urethral strictures in our institution. All patients were assessed preoperatively, and followed postoperatively by physical examination, urinalysis, retrograde and voiding urethrography, uroflowmetry and post-void residual urine measurement. Success was defined as no requirement of additional urethral instrumentation.Results The mean age was 45 years (10-87). The mean stricture length was 5cm (3-10cm). The mean flap length was 6cm. Urinary fistula was the most common postoperative complication. The mean follow-up was 60 months (6-120). The overall success rate was 88%. Recurrent strictures were found in 4 patients (5%) at 1 year. At 3 year follow-up, 5 (7%) more patients had recurrences. All recurrences were managed by internal urethrotomy.Conclusions Substitution urethroplasty using penile skin flap appear to be a safe and efficient technique for the treatment of a long and complex anterior urethral stricture. It provides encouraging cosmetic and functional results.

HighlightsMetastases to gallbladder from renal cell carcinoma are very rare.Most of the cases are diagnosed incidentally, and both clinical presentation and physical examination are unspecific.Imaging although its specificity can’t make the difference between primary gallbladder carcinoma and metastasis from RCC.Only pathological examination of the specimen after cholecytectomy with immunochemistery can assess the diagnosis.

The nutcracker syndrome (NCS) is rare and often misdiagnosed because it embraces an extended non-pathognomonic spectrum of symptoms that imply a difficult diagnosis. Ultimately it may be associated with substantial morbidity and even life-threatening events. Mixed NCS with renal vein duplication is an exceptional variety, have previously been reported to the best of our knowledge. We report a rare case of an 18-year-old boy who presented with a long history of abdominal, pelvic and left flank pain, fatigue and higher bilateral varicocele. Computed tomographic angiography, Doppler ultrasonography and venography were performed revealed left renal vein duplication with dilated retroaortic and preaortic branchs, entrapped respectively between the aorta and the vertebral column and in the aortico-mesenteric space, with extensive and complex varices of the deep pelvic venous plexus; promoting the mixed renal NCS. Auto transplantation of the left kidney was suggested, but refused by the patient; and only the varicocele was managed. The patient is still suffering from his severe initial symptoms. Diagnosis is difficult and should be considered in patients with inexplicable flank or abdominal pain. Our purpose is to raise clinician's awareness for this condition so that they will be more likely to diagnose it. This will facilitate prompt diagnosis and treatment.

Müllerian duct cysts result from an abnormality in regression of the Müllerian system. They may occasionally give rise to symptoms. We report an unusual case of acute urinary retention in an old man caused by a giant Müllerian duct cyst.A 77-year-old man presented with of acute urinary retention. After bladder drainage, digital rectal examination found a large soft supraprostatic mass. Transrectal ultrasound and computed tomography scans revealed a large multilocular retrovesical cystic mass. The patient underwent open surgical resection of the cyst. Histologically, the cystic lesion was lined with stratified cubocolumnar cells, consistent with a Müllerian duct cyst.Acute urinary retention in the elderly is not always related to prostatic diseases. Other causes, even congenital ones, may be involved
