Antegrade pyelography versus unenhanced multidetector CT in the assessment of urinary-tract stones after percutaneous nephrostomy insertion: a prospective blinded study.

Background And Purpose: In patients with a percutaneous nephrostomy tube (PCN) inserted for symptomatic stone disease, antegrade pyelography is an accepted modality to assess the collecting system and residual stone status prior to PCN removal. Recently, unenhanced multidetector CT (UMDCT) has shown its superiority for the assessment of urinary-tract stones. Comparison of UMDCT with antegrade pyelography has never been done; hence, our aim was to compare the two methods for the assessment of urinary stones in patients with a PCN.

Extracorporeal shock wave lithotripsy for large ureteral stones using HM3 lithotriptor.

Purpose: We assessed the efficacy of extracorporeal shock wave lithotripsy for large (more than 10 mm) ureteral calculi with the unmodified Dornier HM3 lithotriptor.

Materials And Methods: A total of 96 consecutive patients with large ureteral stones were treated with shock wave lithotripsy using an unmodified HM3 lithotriptor. Patients, stone characteristics, preliminary treatment before shock wave lithotripsy, additional procedures after shock wave lithotripsy, complications and clinical outcomes were assessed.

Diagnosis and treatment of urinary tract complications in Crohn's disease: an experience over 15 years.

Background: Urinary tract complications in Crohn's disease are common but treatable, and often present diagnostic and therapeutic dilemmas.

Purpose: To determine the incidence of urinary tract complications in patients with Crohn's disease in Israel and to report an experience over 15 years of patients with Crohn's disease, with the aim of illustrating the diverse patterns of presentation, and thereby broadening the approach to diagnosis and treatment.

Methodology: Clinical and radiological findings of 312 patients with Crohn's disease were reviewed.

Left hydronephrosis caused by Crohn disease successfully treated conservatively.

We report the case of a 35-year-old man who presented with fever, diarrhea, and a left abdominal mass. Diagnostic studies confirmed Crohn disease and revealed an abdominal mass obstructing the left ureter with hydroureter and hydronephrosis. The patient was successfully treated conservatively, with corticosteroids and mesalamine, A review of the literature indicates a predominance of right ureteral involvement in Crohn disease, associated with a high incidence of ileocecal disease.

A müllerian prostatic cyst protruding into the base of the urinary bladder.

The unique appearance of a midline prostatic cyst is reported. The cyst presented as a round-shaped filling defect at the base of the urinary bladder during an intravenous pyelography study. Transabdominal sonography showed the mass to be a midline prostatic cyst.

Effect of distilled water and bacillus Calmette-Guérin on exfoliated bladder tumor cells.

The effect of distilled water on exfoliated tumor cells from transitional bladder carcinoma was compared to the effect of bacillus Calmette-Guérin (BCG; a nonspecific immunotherapeutic agent) dissolved in either saline or distilled water. The experiment was controlled by comparison to the effect of saline on tumor cells under the same conditions. Distilled water proved as effective as BCG in distilled water (p less than 0.

Incomplete quadruplication of urinary tract with contralateral agenesis of the kidney.

We describe here the first case of an exceptional anomaly consisting of an incomplete quadruplication of the urinary tract in a solitary left kidney. A review of the English literature failed to document such a case.

An operation for incisional lumbar hernia.

To date, no standard technique for incisional lumbar hernia repair can be recommended since it depends on the size of the defect in the transversalis fascia. A new technique for this purpose, by using plication of the normal fascia, is described.

Excretion of urinary protein induced by extracorporeal piezoelectric lithotripsy.

An investigation was carried out into renal injury caused by extracorporeal piezoelectric lithotripsy (EPL) using an EDAP lithotriptor. Four urinary proteins, with a molecular weight range of 160000-14500, immunoglobulin G (IgG), N-acetyl-beta-glucosaminidase (NAG), albumin and lysozyme, were monitored in 27 patients 1 day before and 1, 7, 30, 90 and 180 days after unilateral EPL treatment. All patients had non-obstructive renal stones, previously untreated.

[Disintegration of urinary stones].

Since January 1988 we performed 520 extracorporeal lithotripsy procedures for urinary stones with the EDAP LT-01 device. The calculi were localized by ultrasonography and the destructive energy was piezoelectrically generated. Treatment was on an ambulatory basis, without local, regional or general anesthesia.

Urinary retention due to catheter occlusion by worms.

Herein we report a very rare case involving acute occlusion of a Foley catheter by worms. The treatment consisted of removal of the occluded catheter followed by bladder washing with a Betadine solution mixed with normal saline and introduction of a new catheter.

Lich-Gregoir anti-reflux operation: a surgical experience and 5-20 years of follow-up in 149 ureters.

The surgical management of vesicoureteral reflux and the choice between the many good procedures available continue to be debated by urologists. The goal of each procedure is to achieve as normal a function of the urinary system as possible, to eliminate urinary tract infections, and thus to prevent further kidney damage. We present our experience in 149 antireflux repair operations with a technique first described by Lich and Gregoir in 1961.

Primary giant calculus in urethral diverticulum.

Urethral stone is a rare clinical entity and usually encountered in men with urethral stricture or diverticulum. They are exceedingly rare in females secondary to the low incidence of vesical calculi and short urethra. We report a very rare case of a primary giant calculus in a urethral diverticulum of a female.

Pitfalls in the treatment of urological injuries.

'Pitfall' is a trap made by digging a hole in the ground and concealing its opening, and any danger or difficulty that is not easily anticipated or avoided. It is our intention in this article to point out the traps, dangers and difficulties involved in our treatment of three urological injuries. It is clear that the pitfalls are due to the inexact interpretation of parameters used.

Hypokalemic familial periodic paralysis: a case report.

The perioperative management of patients with hypokalemic familial periodic paralysis is well known and has been described previously. This disease does not preclude surgery as long as the surgical team is aware of the diagnosis preoperatively. We describe herein a patient with familial periodic paralysis diagnosed the first time 1 day after undergoing surgery.

Idiopathic calcinosis of scrotum.

A case of idiopathic calcinosis of the scrotum is presented. This term has been applied to an uncommon disorder characterized by solitary or multiple, firm painless papules or nodules of the scrotum that usually appear during childhood or early adult life. The lesions are skin colored to white-yellow, increase in size and number, may itch or drain a chalky white material.

Urethro-thigh fistula. Report of 2 cases.

Two rare cases of urethro-thigh fistula are described. Both of them occurred following pelvic trauma. We suggest that trauma, hematoma and infection, suppuration, are the etiology for the development of fistula from a torn urethra to the thigh.

Carcinosarcoma of the prostate.

Carcinosarcoma of the prostate is a very rare malignant tumor in men. Only 4 cases have been reported in the English literature. We give herein the 5th case report of carcinosarcoma of the prostate.
