  • Stress urinary incontinence (SUI) is a common condition that primarily affects women. Here, we investigate the effects of human adipose-derived stem cells (ADSCs) in a rodent model of SUI. Female Sprague-Dawley rats at 7 weeks of age were randomly divided into three groups (n=8 per group): sham-operation, SUI-induction by transabdominal urethrolysis, and SUI-induction followed by transplantation of human ADSCs into the urethra. The abdominal leak point pressure at 8 weeks after the operation was markedly decreased by transabdominal urethrolysis, confirming successful induction of SUI. Interestingly, transplantation of human ADSCs into the urethra significantly blunted the decrease of abdominal leak point pressure in SUI-induced rats. Accordingly, we observed expression of ${\alpha}$-smooth muscle actin in a significant proportion of transplanted ADSCs, indicating differentiation of ADSCs into smooth muscle cells in the urethra. Moreover, the SUI-induced elevations of c-Fos immunoreactivities in the pontine micturition center (PMC) and in the ventrolateral periaqueductal gray (vlPAG) were clearly suppressed by transplantation of human ADSCs. These results imply that human ADSCs can be an effective therapeutic modality to ameliorate the symptoms of SUI.

  • Choledochal cyst is a congenital anomaly with classic triad of abdominal pain, jaundice and right upper abdominal mass. Bile peritonitis caused by cyst rupture is relatively not rare in infancy. The mechanism of rupture must be epithelial irritation of the biliary tract by refluxed pancreatic juice caused by pancreatico-biliary malunion associated with mural immaturity in infancy, rather than an abnormal rise in ductal pressure or congenital mural weakness at a certain point. We experienced a case of bile peritonitis caused by spontanenous rupture of choledochal cyst in a 10-month-old girl presented with abdominal distension, persistent fever, diarrhea, irritability and intractable ascites. She was presumed as having bile peritonitis by bile colored ascitic fluid with elevated bilirubin level and diagnosis was made by $^{99m}Tc$ DISIDA hepatobiliary scan showing extrahepatic biliary leak. The perforated cyst was surgically removed and the biliary tree was reconstructed with a Roux-en-Y hepaticojejunostomy.
