Treatment of ureteral calculi with extracorporeal shock wave lithotripsy using the Lithostar device.

Shock wave requirements for fragmentation and the ultimate outcome after extracorporeal shock wave lithotripsy (ESWL) with the Lithostar device were analyzed in 107 renal units with solitary ureteral calculi. In situ treatment was done in 54 stones without prior manipulation and in 15 after failure of endoscopic manipulation. A total of 25 ureteral calculi was treated after bypass with a ureteral catheter or stent and 13 after push back to the pelvicaliceal system. Shock wave requirement for fragmentation was significantly higher for calculi of 101 to 400 mm. X mm. when compared with the requirement for smaller calculi. Shock wave requirement was also significantly higher for patients with similar sized stones treated in the prone compared to the supine position. The average number of shock waves required for disintegration was not significantly different among in situ or any of the manipulation categories of similar sized stone populations. Over-all satisfactory clearance was achieved in 77.5% of the treated ureteral calculi. Clearance status was unaffected by size up to 400 mm. X mm. and the position of the patient during treatment (prone or supine). Clearance of ureteral stones treated in situ without prior manipulation (76.5%) was numerically inferior, although statistically insignificant, to that for successfully manipulated calculi (bypassed 88% and pushed back 92.3%) but it was significantly better than the outcome obtained after failed manipulation (46.2%). ESWL with the Lithostar device is a successful mode of treatment within the entire ureteral length, and a vigorous attempt at push back before lithotripsy is unnecessary.

Antenatal ultrasonic diagnosis of Meckel Gruber syndrome (a case report with review of literature).

Meckel Gruber syndrome is a rare autosomal recessive disorder with major characteristic features consisting of occipital encephalocele, polydactyly and polycystic kidneys along with other associated malformation. Antenatal ultrasonic examination can establish the correct diagnosis by identifying at least two of the major features described. The antenatal ultrasonic findings and pathology of this uncommon entity are discussed.

Functional bladder neck obstruction in females--a revisit.

Functional bladder neck obstruction is supposed to be nonexistent or a very rare clinical disorder. In the past two and a half years, detailed synchronous, video pressure flow EMG studies were done in all the female patients who had evidence of obstructed voiding, poor flow and acute or chronic retention. The subjects of this study are nine females who had high sustained detrusor pressure, high opening pressure, low uroflow and silent sphincter during pressure-flow EMG study. A simultaneous urovideo recording showed either a closed bladder neck, inadequate funneling, intermittent or improper opening during voiding (when Pdet was high and sustained). These patients did not have any anatomical urethral obstruction, neurogenic disorder or systemic disease (like diabetes) affecting voiding. This stringent criteria of functional bladder neck obstruction was observed in nine patients. Five patients had acute or chronic retention and three patients had varying degree of renal failure. Initially all patients were managed by clean intermittent self catheterisation (CIC). Alpha blockers were empirically tried in six patients and had shown variable results. Bladder neck incision (BNI) was performed in two patients with rewarding success.

Selection of operative procedure for circumcaval ureter (type I). A rational approach.

The surgical treatment of circumcaval ureter (type I) should eliminate the ureteric obstruction which is of variable causation. At operation, the aetiology of the obstruction can be determined by inspection of the extent of ureteric dilatation, perfusion-pressure study and calibration of the lumen. Using this approach, the cause of the obstruction was found to be nonstenotic intrinsic obstruction of the retrocaval segment in two cases of type I circumcaval ureter. In these patients, resection of the obstructing segment and uretero-ureterostomy were carried out. The third patient had pelviureteric junction stenosis which was treated by dismembered pyeloplasty after ureteric relocation.

Management of complicated strictures of the urethra in men.

Of 250 men with urethral strictures seen over a period of 40 months 50 had complications such as periurethral abscesses, inflammatory masses, urethral fistulas, sinuses and urinary extravasation. The strictures were multiple and showed diffuse involvement of the urethra; 90% were of inflammatory origin.
