Ureterocalycostomy for postpyelolithotomy stenosis after failure of intubated infundibuloplasty.

Extended pyelolithotomy for staghorn calculus in a uremic patient with solitary functioning kidney was followed by development of stenosis of the infundibulum draining the superior and middle calyces. Drainage of the lower calyx down the ureter remained intact. Intubated infundibuloplasty proved unsuccessful since scarring and occlusion promptly recurred. Anastomosis of the middle calyx to the ureter was then performed with good results. We believe this is the first reported case of ureterocalycostomy for providing drainage to the middle calyx without lower polar nephrectomy.

Peripelvic extravasation and formation of perinephric urinoma after cystoscopy.

A hitherto undescribed complication of cystoscopy is reported wherein peripelvic extravasation and perinephric collection of urine resulted from conventional cystoscopic examination in a patient with a small-capacity bladder and vesicoureteral reflux. Prompt recognition, institution of indwelling catheter drainage, and massive antibiotic therapy led to spontaneous resolution of the flank mass. In similar cases, we suggest the use of an Iglesias resectoscope with a continuous flow and suction evacuation, even for cystoscopy and bladder biopsy.

Clinical import of beta-adrenergic activity in the proximal urethra.

Beta-adrenergic activity of the proximal urethra was studied in 11 patients. Maximum urethral pressure was recorded before, and 20 and 60 minutes after the intravenous administration of 0.5 mg. orciprenaline sulfate. There was a 40 per cent or more decrease in the maximum urethral pressure in 6 of the 11 patients. Beta-adrenoreceptor agonists could prove useful in facilitating vesical emptying by reducing urethral resistance in patients with neurogenic bladder dysfunction.

Beta-adrenergic activity in human proximal urethra: a study with terbutaline.

Beta-adrenergic activity in the proximal urethra was studied in 15 patients with neurogenic bladder dysfunction owing to spinal cord injury or to neurogenic disease. Maximum urethral closure pressure was recorded before and after the administration of terbutaline, a beta-2 agonist. The average decrease in maximum urethral closure pressure after subcutaneous injection of terbutaline was 40.46 per cent and this was significant (p less than 0.001). The clinical implications of this finding are discussed.

Ureteric diverticula: ureterodiverticular reflux and yo-yo effect. A television study with spot filming.

Two cases of ureteric diverticulum are presented. Repeated infective episodes were the main presenting features in one, whereas intermittent attacks of colicky pain brought the other patient in for clinical assessment. Fluoroscopic evaluation of the latter patient demonstrated free ureterodiverticular reflux and yo-yo phenomenon. Following diverticulectomy the pain completely disappeared.

Value and limitations of testicular scanning by in vivo labelling of RBC with 99mTc.

When a scrotal affection cannot be diagnosed confidently by correlation of clinical history and physical examination, testicular scanning with 99mTc is a useful adjunct diagnostic modality. In vivo labelling of red blood cells with 99mTc was achieved by prior oral administration of 200 mg of stannous chloride. This helped to obtain satisfactory scintigraphy with a rectilinear scanner. This procedure was found to be useful in the adult with recent tender testicle in whom the torsion of the testis could not be clinically differentiated from epididymo-orchitis. Another area of scan's valuable clinical application was in the early diagnosis of testicular abscess in patients with epididymo-orchitis not responding immediately to antibiotic therapy. The study also proved to be a useful, non-invasive method for follow-up assessment of a case of torsion of the testis where detorsion and orchiopexy was performed as well as in case of rupture of a testis after orchiorrhapy.

Role of dopamine receptors in vesicourethral function. A urodynamic study with dopamine receptor antagonist metoclopramide.

The effect of intravenous administration of 20 mg metoclopramide, a dopamine receptor antagonist upon cystometry, urethral pressure profile and external urethral sphincter electromyography (EMG) was investigated in 10 patients with neurogenic bladder dysfunction. No significant change was noticed in detrusor reflex activity or in peak urethral pressure. This suggests that dopamine receptors are not important in vesicourethral function. The increase in sphincter EMG activity observed was probably due to the cholinergic effect of metoclopramide.

Further observations on vesicourethral dopamine receptors--a urodynamic study with haloperidol.

The effect of intravenous administration of 5 mg of haloperidol, a dopamine receptor antagonist upon cystometry, the urethral pressure profile, and the external urethral sphincter electromyography (EMG) was investigated in eight patients with neurogenic vesical dysfunction. There was no change in the detrusor reflex or in the sphincter EMG activities, but the peak urethral pressure decreased. The possible reasons for the difference in the above result as compared to our previous study using metoclopramide, another dopamine receptor antagonist, are discussed.

Non-operative management of a pelvic hydatid cyst communicating with the bladder.

Two cases are reported of spontaneous rupture of pelvic hydatid cysts into the bladder, which were managed conservatively. The resulting communication between the bladder and the cyst was used advantageously for intravesical instillation of 20% saline to destroy the germinal layer of the hydatid cyst and daughter cysts. Sequential cystographic studies showed disappearance of the extrinsic pressure effect on the bladder as the daughter cysts were evacuated repeatedly per urethram after instillations. Spontaneous sealing off of the communication was documented and confirmed by cytoscopy in 1 case. A plea is made to adopt a non-operative approach in such cases, which permits intravesical and, hence, intracystic scolecidal agent instillation and achieves spontaneous evacuation of daughter cysts. Other factors encouraging conservative management whenever possible are the reportedly high recurrence rate of hydatid cysts postoperatively, the morbidity described with complete excision of pelvic and other hydatid cysts, and the inherent slow process of recurrence (between 5 and 20 years) after complete evacuation of daughter cysts.

Vaginocystography in vesicovaginal fistulae.

The importance of vaginocystography as an additional tool to excretory urography and cystoscopy in assessment of vesicovaginal fistulae is emphasized. A simple technique applicable even to large and multiple fistulae or a capacious vagina is described and discussed.

Spontaneous rupture of renal pelvis during postobstructive diuresis.

A case of spontaneous rupture of the renal pelvis during postobstructive diuresis following spontaneous relief of anuria in a patient with postpyelolithotomy retroperitoneal fibrosis, is described. The unusual etiopathological setting which predisposed to the occurrence of such a rare phenomenon and its treatment implications are discussed.
