Giant hydronephrosis is defined as an extensive dilation of the pyelocaliceal cavities occupying a large part of the abdominal cavity or as a dilation filled up with more than a liter of urine overflowing the median line. This is due, more often, to pyelo-ureteral junction syndrome. Obstruction due to ureterocele complicated by lithiasis is a very rare cause of giant hydronephrosis. We here report the case of a 45-year old patient with a history of right lumbar pain which hadn't been investigated, presenting with abdominal mass evolving over the last few years associated with intermittent constipation. Clinical examination showed asymmetrical abdominal distension with dullness above the median line. Ultrasound showed multi-compartmentalized fluid-filled mass occupying all the right abdominopelvic region and pressing the digestive structures. Uroscanner showed right giant ureteropyelocaliceal dilation (pyelon measuring 15.2cm) completely eroding the renal parenchyma with absence of contrast agent excretion, upstream of ureterocele complicated by a stone measuring 2cm. Laparoscopic nephroureterectomy was performed. Post-operative suites were simple.

Urinary fistulas are a rare late complication after radiotherapy for prostate cancer. We here report the case of a 76-year old patient who had undergone radical prostatectomy 4 years before followed by external beam radiotherapy for prostate cancer. The patient presented with recurrent thigh swelling . Clinical examination showed renitent and painless mass at the level of the medial compartment of the right thigh. Ultrasound followed by CT scan showed big homogeneous fluid collection in the inner thigh exercising a slight compression on femoral vessels. Surgical drainage was performed removing 900 ml cloudy liquid whose bacteriological examination was negative. Post operative suites were marked by a sharp reduction of diuresis. However significant quantity of clear liquid continued to be drained. Given the patient's clinical picture, methylene blue test followed by retrograde cystography were performed confirming the diagnosis of fistula originating from the ureterovesical junction. The drainage of the collection was obtained through the insertion of a local probe for several weeks.

Check for updatesand finally carrier of a vesical catheter. The ultrasound exploration showed a prostate enlargement which volume was estimate to 60g with intravesical prostate protrusion. In the bladder was the presence of multiple stones.The Kidney, Ureter, and Bladder (KUB) X-ray revealed an intravesical necklace drawn by small stones (Figure 1). The rest of biologic assessment was normal. An open prostatectomy was indicated in front of this clinical picture. An enucleation of prostatic adenoma, and removal of the stones were performed.Figure 1A shows the patient's KUB showing the arrangement of intravesical necklace calculi, Figure 1B

Bacillus Calmette and Guérin (BCG), widely used as a vaccination to prevent tuberculosis, is also used as immunotherapy, by intrabladder instillation, to treat superficial bladder cancers and prevent recurrence. Complications following instillation of BCG are most often localized reactions, such as cystitis or hematuria. They can more rarely be generalized and potentially severe such as hepatitis, pneumopathies, aortitis, and localization to hematopoietic tissue. We have reported the observation of a 47-year-old patient followed up for a bladder tumor operated for transurethral resection of the bladder, then having benefited from an instillation of BCG therapy complicated by occurrence a week later of an acute hepatitis. The diagnostic time was 2 days, and the outcome was favorable with corticosteroid therapy.
