Purpose: Through this work we are going to demonstrate the interest and the contribution of the percutaneous nephrostomy in obstructive anuria and in pyonephrosis.
Patients And Methods: It is a retrospective study concerning 42 cases. The average age of the patients is 50 years (19-80 years). The sex-ratio is 26 men for 16 women. The nephrostomy was realized in first intention or after failure of ascent stent on 33 patients for an obstructive anuria and nine patients for a pyonephrosis.
Results: Improvement of the renal function was noted in 100% of obstructive with anuria and apyrexy in every case of pyonephrosis. No major complication arose during the realization of the nephrostomy. The long-term prognostic depends on the etiology.
Conclusion: The percutaneous nephrostomy constitutes a saving, effective and temporary solution in the strategy of the coverage of obstructive anuria and pyonephrosis.

Background And Objectives: Multiple primary malignant tumors represent a small percentage of the total number of oncological cases and can involve either metachronous or synchronous development and represent challenges in diagnosis, staging, and treatment planning. Our purpose is to present a rare case of bladder adenocarcinoma in a female patient with multiple primary malignant tumors and to provide systematic review of the available literature.
Materials And Methods: A 67-year-old female patient was admitted with altered general condition and anuria.

Article Synopsis
- - Obstructive nephropathy (ON) is a reversible condition that can cause acute kidney injury, resulting from blockage in the urinary tracts; it may not always present with hydronephrosis, leading to a form called non-dilated obstructive uropathy (NDOU).
- - NDOU typically occurs in older males and can present symptoms like low urine output, abdominal pain, and high serum creatinine levels; it often stems from external ureter compression due to conditions like retroperitoneal fibrosis or tumors.
- - Effective treatments include minimally invasive methods like ureteric stenting or nephrostomy, and timely diagnosis is crucial for managing the obstruction and potentially reversing kidney damage.

Inflammatory bowel disease (IBD) is an inflammatory clinical entity with many extraintestinal symptoms, including urinary tract manifestations. However, the bilateral ureteral obstruction is extremely rare. We report a case of bilateral ureteral obstruction in a 12-year-old male patient with ulcerative colitis (UC).

Gross hematuria is one of the most common complications in postrenal transplant patients, accounting for 12% of all renal recipients. The management plan in these cases varies depending on different entities, including infection, renal cell carcinoma, chronic graft rejection, kidney calculus, or recurrence of primary disease. On the other hand, vascular malformation like arteriovenous malformation was less likely to be mentioned due to a lack of consensus in the natural history, pathogenesis, and current management.
