Extracorporeal shock wave lithotripsy-induced perirenal hematomas.

Subcapsular or perirenal bleeding is the most commonly experienced adverse effect directly attributable to externally applied shock waves. The first consecutive 3,620 extracorporeal shock wave lithotripsy treatments with the HM3 Dornier lithotriptor at our institution resulted in 24 hematomas in 21 patients, for an incidence of 0.66 per cent.

Gastrocystoplasty and colocystoplasty in canines: the metabolic consequences of acute saline and acid loading.

An experimental canine model was developed to quantitate the net transmural ion flux of colon and gastric segments used for augmentation cystoplasty. Gastrocystoplasty (4) or colocystoplasty (4) was constructed in 8 female mongrels. Acute intravenous saline and acid loading experiments were performed 2 to 4 weeks after cystoplasty.

Prevention of post-prostatectomy vesical neck contracture by prophylactic vesical neck incision.

Most vesical neck contractures occur after resection of adenomas weighing less than 20 gm. This complication is believed to be secondary to excessive resection or fulguration of an undilated bladder neck. Prophylactic bladder neck incision was performed in conjunction with transurethral resection of the prostate on 114 patients with prostatic adenomas weighing less than 20 gm.

Extracorporeal shock wave lithotripsy in patients with a solitary kidney.

Extracorporeal shock wave lithotripsy was used to treat 68 patients with renal calculi in a solitary kidney. Epidemiological information, including stone number, size and location, was similar to that of other patients treated with extracorporeal shock wave lithotripsy. Renal function as measured by serum creatinine changed negligibly in the majority of the patients.

Intestinocystoplasty in combination with clean intermittent catheterization in the management of vesical dysfunction.

Intestinocystoplasty in combination with clean intermittent catheterization has been used in the management of 60 young patients with bladder dysfunction. Of the patients 39 (65 per cent) had the primary diagnosis of myelomeningocele, 8 had sacral agenesis, 3 had spinal cord tumors and 1 had spinal cord trauma. The remaining 9 patients had either congenital, surgical or traumatic loss of all or a large portion of the bladder.

Hypospadias repair without a bladder drainage catheter.

We report on 44 consecutive patients who underwent 1-stage hypospadias repair based on a urethral splent (silicone pleated stent). The severity of hypospadias ranged from subcoronal in 12 cases and distal in 23 to midshaft in 4 and penoscrotal in 5. In the first 15 patients of this series the splent was used with a suprapubic tube.
