In order to understand the pathology of incontinence, it is important to investigate urinary symptoms, urological and neurological examinations and urodynamics. There are two kinds of incontinence. One is true incontinence in which urine passes through urethra, and the other is false incontinence due to the ectopic opening of the ureter, for example to the vagina. The former includes stress incontinence, urge incontinence, reflex incontinence, overflow incontinence and total incontinence. Stress incontinence occurs with the sudden increase of abdominal pressure such as cough, running and exertion. The cause of stress incontinence is thought to be weakening of pelvic floor muscles after delivery or aging. In these patients, the bladder base and urethra move downwards and backwards, which make the posterior vesico-urethral angle more than 120 degrees. Treatment of stress incontinence includes pelvic floor exercise, administration of alpha-stimulants which increase the tonus of the internal sphincter and surgery to elevate the urethra. Urge incontinence is observed when detrusor instability occurs. It is also seen in patients with neurological diseases such as multiple cerebral infarction or with benign prostatic hypertrophy (BPH). Treatment of urge incontinence includes administration of anticholinergics to decrease bladder hyperreflexia. Reflex incontinence is seen in patients with spinal cord disorders. It occurs due to reflex contraction of detrusor and the treatment involves administration of anti-cholinergics. Overflow incontinence is seen in patients with voiding difficulties due to BPH. It occurs when residual urine increases and when the intravesical pressure exceeds urethral pressure on body movement. Treatment for this is intended to improve voiding difficulties. Total incontinence occurs when total sphincter function is damaged.(ABSTRACT TRUNCATED AT 250 WORDS)

An unusual case of 2 concurrent primary renal tumors within the same kidney is reported. A 70-year-old woman presented with gross hematuria when she was in the hospital for cerebral infarction. Excretory urography revealed a marked expansion of the right kidney with no renal function. CT scan showed a mass arising from the right kidney, the hydronephrotic right renal pelvis, and a mass in the lower right ureter. Selective renal angiogram showed marked neovascularity of the mass. There was an encasement of the intrarenal artery to the lower pole. Angiographic findings were highly suggestive of a renal cell carcinoma with a second neoplasm in the renal pelvis. Subsequently, the patient underwent right radical nephroureterectomy and partial cystectomy. Section of the removed specimen revealed a 4.0 X 3.8 cm solid tumor confined to the kidney in the upper pole and a transitional cell carcinoma arising from the renal pelvis. In addition, transitional cell carcinoma was present in the distal ureter.

We report a case in which retroperitoneoscopic pyelolithotomy was the procedure selected to treat a large stone in the upper urinary tract. A 71-year-old woman who had multiple cerebral infarction and dementia was admitted with a persistent high fever unresponsive to antibiotics. The diagnosis was pyelonephritis and urosepsis associated with ureteral calculus. A large calculus(3.0 x 2.0 cm)was found in the left ureter at the L3 level. She underwent nephrostomy of the left side. After the patient's general condition had improved, surgery was performed successfully with an uneventful recovery. The findings in this case confirm that retroperitoneoscopic surgery allows removal of a large stone in a single, minimally invasive procedures.
