Stent placement can be useful for saving a kidney at risk for postrenal acute renal failure due to the increased hydrostatic pressure, swelling and infection (pyelonephritis and pyonephrosis) caused by an obstructing stone.

In some of the bladder reconstructions, the bladder is augmented with the addition of a segment of the large intestines to increase the volume capacity of the reconstructed bladder. (http://www.med.umich.edu/1libr/urology/BladderAugmentation.pdf) In the complete primary repair of exstrophy (CPRE) the bladder closure is combined with an epispadias repair, in an effort to decrease costs and morbidity. This technique has, however, led to significant loss of penile and corporal tissue, particularly in younger patients. In females treatment has included: Surgical reconstruction of the clitoris which is separated into two
