We report two cases of urinary diversion through an appendix. Case 1. An 81-year-old man was hospitalized with oliguria. The patient had a past history of left nephro-ureterectomy for left ureteral tumor. Ultrasound showed right hydronephrosis due to recurrence in the bladder and right ureter. A total cystectomy and partial ureterectomy were carried out, and an appendix conduit was constructed because the ureter was not sufficiently long for ureterocutaneostomy. Case 2. A 68-year-old woman with diabetic neurogenic bladder, hypothyroidism, and chronic obstructive lung disease was hospitalized with the complaint of difficulty in self-catheterization. Continent vesicostomy was carried out according to the method of Mitrofanoff using the appendix. Both patients were tubeless and without postoperative complications before discharge. Appendix conduit and Mitrofanoff operation, which can be performed by a simple surgical procedure, are considered to be applicable to poor risk cases.

Therapy for obstructive uropathy is largely determined by whether the obstruction involves one or both kidneys, and by the age of the patient. In the infant and child, obstructive uropathy is almost always due to a congenital malformation of the ureter, bladder, or urethra. Ultrasonographic prenatal diagnosis has permitted early detection and even fetal intervention for posterior urethral valves, although this form of treatment must be considered experimental at present. More important to the affected infant than optimal renal development is the prevention of pulmonary hypoplasia, which is a consequence of fetal oliguria and oligohydramnios. Congenital ureteropelvic junction (UPJ) obstruction is generally unilateral, and although there is controversy regarding the timing of surgical correction, current evidence favors early pyeloplasty. In the adult, obstructive nephropathy is often acquired, with ureteral obstruction usually a consequence of nephrolithiasis. Removal of the stone can be accomplished surgically or by lithotripsy. Bladder outlet obstruction is usually secondary to prostatic hyperplasia, which may progress slowly, allowing a delay in surgical intervention. Neurogenic bladder may require intermittent catheterization or cholinergic therapy; those with hypertonic bladder may benefit from anticholinergics. Regardless of the patient's age, prompt and accurate diagnosis is essential to planning an optimal strategy for the management of obstructive uropathy.
