Role of human adipose-derived stem cells (hADSC) on TGF-β1, type I collagen, and fibrosis degree in bladder obstruction model of Wistar rats.

Introduction: Bladder outlet obstruction (BOO) was caused by a series of histological and biochemical changes in the bladder wall, through the inflammation process in the bladder wall, hypertrophy and fibrosis. ADSC has an important role in bladder regeneration.

Methods And Materials: This study was an experimental randomized study using male Wistar rats which were monitored at 2 and 4 weeks to determine the effect of ADSC therapy on TGF-β1 type I collagen, and degree of fibrosis.

Reno-duodenal fistula as a rare complication of percutaneous nephrostomy: A case report.

Renoduodenal fistula is a rare condition where a pathological tract is formed between the kidney and duodenum. This condition is caused by various etiologies, such as tuberculosis, malignancy, percutaneous nephrostomy procedure, cryoablation procedure in malignancy, and chronic infection. In this case, we report a case renoduodenal fistula caused by large staghorn calculus, precipitated by a previous history of trauma.
