bjective: The study aimed to clarify the prevalence of urinary tract infection due to double J-J tube by describing its clinical, bacteriological, therapeutic, and evolutionary aspects in the urology department in Ibn Rochd University Hospital in Casablanca. Patients and methods: The study followed the descriptive method, from January 01, 2019, to December 31, 2019, examining the records of patients who have had a J-J catheter inserted as a type of upper urinary tract bypass and in the meanwhile, they get a urinary tract infection. Results: Ninety-two cases were included in our study. The average age of the patients was 48 years with ranges of 17 and 79 years. The sex ratio M/F was 1.3. Most Etiologies of the cases were dominated by urinary lithiasis by 47% of cases, followed by tumor caused cases with 37.27%. As for the main clinical signs, Lower back pain had taken the place as it was found in 31% of cases. The bacteriological isolation found Gram-Negative Bacillus as the main germ in 86% of cases with the predominance of Escherichia coli (E. coli) (44%). The main antibiotic prescribed was fluoroquinolones in 32% of cases. Conclusion: J-J tube insertion is an effective and minimally invasive technique of bypassing the upper urinary tract to preserve kidney function but it could cause complications including urinary tract infection hence the need to respect preventive measures.

Penile Fournier's gangrene is extremely rare due to the rich blood supply of the penis. It has only been reported in a few cases in the literature. Prompt surgical exploration, antibiotic therapy, and meticulous postoperative care are the cornerstone in the successful mangement of this high-mortality emergency. We present a rare case of penile Fournier's gangrene with total necrosis of the penis necessitating penectomy in a 70-year-old patient who is well advanced, with complete perineum healing. The goal of this article is to illustrate this rare case, as well as to explain what causes it and how to manage it.
