Only four cases have been reported.1 We have recently seen a fifth case of this phenomenon, our first in a series of 157 renal allografts performed at the University of California Medical Center, San Francisco, between January 1964 and March 1969. This is the first case to be reported in which the rupture was delayed beyond the first few days of transplantation and represents a new complication of renal transplantation in man.

He had a history of enuresis until the age of 12 years, when intravenous urography demonstrated bilaterally hypoplastic kidneys. At that time, the serum creatinine level was 3.8 mg/100 cc, the creatinine clearance was 24 ml/min, the blood urea nitrogen
