Viral urinary infection: A report of three cases

[Case 1] A 60 -year-old man was referred to our hospital due to gross hematuria six months after unrelated bone marrow graft. Because abdominal CT showed bilateral hydronephrosis, we undertook the placement of ureteral stents on the same day. HHV6 and ADV were detected by urinary test After placement of the stents, gross hematuria disappeared, and his course was uneventful with good kidney function, but he died by the primary disease. [Case 2] A 36 -year-old woman was referred to our hospital due to gross hematuria one month after umbilical cord blood transplant. Because abdominal CT showed bilateral hydronephrosis, we undertook the placement of ureteral stents. However, we subsequently performed nephrostomy on day 5, because gross hematuria continued. CMV was detected by urinary test. After the nephrostomy was performed, gross hematuria disappeared, and her course was uneventful with good kidney function, but she died by the primary disease. [Case 3] A 49-year-old woman was referred to our hospital due to chilliness and gross hematuria two years and three months after cadaveric renal transplantation. Because abdominal CT showed hydronephrosis at the grafted kidney, we performed nephrostomy on the same day. ADV was detected by urinary test. After the nephrostomy was performed, gross hematuria disappeared, and her course was uneventful with good kidney function. These three cases demonstrated how gross hematuria and kidney function were improved by urinary drainage, including the placement of a ureteral stent and nephrostomy. (Nishinihon J.
