Original research E36case series AbstractIntroduction: Xanthogranulomatous pyelonephritis (XGPN) is an atypical form of chronic pyelonephritis referred to as the ''great imitator'' because the clinical and radiological findings closely resemble other pathological entities, especially for the focal forms. Distinguishing focal XGPN from renal cancer is preoperatively difficult. Methods:We report a total number of 12 pseudotumoural XGPN cases diagnosed and treated in our department. The aim of this study is to try to better understand the clinicopathological profile of XGPN and improve its management. Results: The mean age of patients was 51.52 years. Gender ratio was 0.71. An obstructive renal calculus was noticed in nine patients (75%). Only one patient (8.3 %) presented with loin pain associated with fever, weight loss, asthenia, and increased biological inflammation markers. A bifocal mass was noticed in one case (8.3 %). The average size of the tumour was 6.58 cm. The mass was cystic in three cases (25 %). Perinephral fat strand, thickening of Gerota's fascia, hydronephrosis, and presence of renal calculi was noticed in all solid tumour cases. XGPN was suspected in only one case (8.3%), a percutaneous biopsy showed XGPN lesions treated by antibiotics and a double J drainage. Radical nephrectomy was performed in eight patients (66.7 %) and three patients underwent partial nephrectomy (25 %). No recurrence of XGPN has been noted. Conclusion: Pseudotumoural XGPN is a rare benign disease of the kidney. Its treatment should be conservative. Lack of knowledge of this disease may explain the high rate of abusive nephrectomies. These data should be considered in the future.

HighlightsCondom catheter is frequently used to manage male urinary incontinence but should not be used carelessly or overlooked.Even if they are rare, penile strangulation and gangrene may occur and are severe complications.Treatment is based on debridement, broad-spectrum antibiotics and skin grafting. It may result in partial or total penectomy.Proper care and routine maintenance of condom catheters are mandatory in order to prevent devastating complications.Appropriate care is necessary, especially in debilitated and psychiatric populations.

Background Urogenital tuberculosis is still a frequent presentation, and it constitutes a current public health problem in endemic areas. The clinical presentation of this form of the disease may be misleading. The pseudotumoral type of renal tuberculosis is extremely uncommon. Case presentation We present a case of a 52-year-old African woman who presented with urogenital tuberculosis in its pseudotumoral form. This case was initially diagnosed and managed as renal cancer. Histopathology confirmed the diagnosis of pseudotumoral renal tuberculosis. Conclusions The pseudotumoral form of urinary tuberculosis can be difficult to diagnose. Only bacteriological or histological confirmation allows diagnosis for adequate treatment.

BackgroundSplenogonadal fusion is a rare and benign condition. Diagnosis is challenging for clinicians. Despite its indolence, diagnosis is often confirmed after orchidectomy. Surgery is mandatory, particularly to rule out the extremely rare association with malignancy.Case presentationWe report a case of splenogonadal fusion in a 38-year-old North African man presenting a palpable scrotal mass. We describe clinical aspects, pathogenic hypothesis, radiological features, as well as surgical management principles.ConclusionsSplenogonadal fusion is rarely suspected and diagnosed preoperatively. A diagnosis is made once an ectopic testicular mass is associated with cryptorchidism and suggestive radiological signs. A better knowledge of the clinical and radiological features of splenogonadal fusion provides an opportunity for conservative surgery.

ObjectiveTo analyse the effects of baseline body mass index (BMI) on the postoperative and remote consequences of nephrectomy in living kidney donors, as body weight is conventionally used as an exclusion criterion for kidney donation and a BMI of <35 kg/m2 is often required.Patients and methodsWe retrospectively studied 189 living-related kidney donors who had their nephrectomy between 1986 and 2009 in our urology department. We recorded the BMI at the time of donation, and analysed variables after surgery, and clinico-biological factors remotely. The effect of the initial BMI after surgery and much later after nephrectomy was assessed.ResultsThe mean follow-up was 9.28 years. The mean (range) BMI at the time of donation was 26.5 (18.5–41.1) kg/m2; 33% of donors were overweight (BMI 25–30) and 21% were obese (⩾30), with 10.5% having a BMI of >35 kg/m2. The duration of hospitalisation was not related to the BMI. There was no significant difference between the mean BMI of donors with a simple postoperative history and donors who had complications after surgery. Among obese donors, only 7.7% had a complication, which was a surgical-site infection in all cases. The baseline BMI was higher among donors who maintained normal renal function and no proteinuria than in donors with impaired renal function and/or proteinuria; the difference was not significant. The occurrence of hypertension or diabetes was independent of baseline BMI. Donors with dyslipidaemia had no significantly greater baseline BMI than those with no dyslipidaemia.ConclusionThe BMI at the time of kidney donation does not seem to influence the short- or long-term consequences of nephrectomy in living donors.

Highlights Solitary fibrous tumor is a rare entity, representing 2% of all soft tissue tumors. The disease is usually described in the thoracic cavity, only 105 cases of renal solitary fibrous tumor have been reported. Solitary fibrous tumors are usually asymptomatic thus they are diagnosed as renal cell carcinoma and treated as such. Typical immunohistochemical characteristic is a high positivity for CD34. As solitary fibrous tumor has a malignant potential, careful follow-up is mandatory.
