Spontaneous renal rupture in pregnancy.

A review of the literature reveals 9 cases of spontaneous renal rupture in pregnancy, to which we add another case. Most cases occurred in hydronephrotic kidneys. Four cases consisted of renal rupture without associated infection, or tumor, 3 were associated with abscesses, and 3 ruptured through renal hamartomas. Previously, all ruptured kidneys were removed. In our case the kidney was salvaged satisfactorily by prompt placement of a nephrostomy tube and drainage of the perirenal tissue. Attempt at renal salvage is urged for renal supture in pregnancy.
