Is there a simpler method for predicting lower pole stone clearance after shockwave lithotripsy than measuring infundibulopelvic angle?

BACKGROUND AND PURPOSE: Several anatomic factors influence the clearance of lower pole stones treated with shockwave lithotripsy (SWL). One of these is the infundibulopelvic angle, but its measurement is complex. METHODS: We proposed a more simple measure of caliceal dependence, the caliceal pelvic height (CPH), which we defined as the distance between a horizontal line from the lowermost point of the calix containing the stone to the highest point of the lower lip of the renal pelvis. RESULTS: In 62 patients who had SWL for solitary lower pole stones, a CPH < 15 mm was associated with a stone clearance rate of 92%, whereas with a CPH > or = 15 mm, the clearance rate was only 52% (p < 0.05). A majority (74%) of the patients with an infundibular width of > or = 5 mm were rendered stone free compared with 40% of those with a width of < 5 mm (p < 0.05). CONCLUSION: Measurement of the CPH, in conjunction with other anatomic factors, may more accurately predict the outcome of SWL in patients with lower pole stones.

Intermittent self catheterization versus regular outpatient dilatation in urethral stricture: a comparison.

BACKGROUND: The results of regular intermittent self catheterization were compared with regular outpatient dilatation after endoscopic internal urethrotomy for urethral strictures. METHODS: The records of patients who were treated for urethral stricture disease over a 4-year period from 1991 to 1994 were reviewed. They were either on regular urethral dilatation or were advised to carry out self calibration. A follow-up questionnaire was sent to them and they were asked to attend a review. Student's t-test and Proportion Test were used to find out if there was any significant difference between the two groups. RESULTS: There were 78 patients who were on self calibration and 49 patients on regular urethral dilatation. There was no significant difference between the two groups regarding the duration of follow-up (21.5 and 23.7 months, respectively); the length of stricture (1.5 and 1.7 cm, respectively); and complications (two and four, respectively). However, patients on self calibration had narrower strictures (4.8 and 5.7 F) and a significantly lower restricture rate (5 and 16%). The current urinary stream was compared to the immediate postoperative stream. This showed that a higher number of patients in the dilatation group were voiding at less than 25% of their immediate postoperative flow. People from high and low socio-economic groups were able to carry out self calibration satisfactorily. CONCLUSION: Patients from high and low socio-economic groups found that self calibration resulted in a lower restricture rate and better stream when compared to regular urethral dilatation.

Eosinophilic cystitis--not that uncommon!

The clinical presentation, radiological manifestations and response to therapy of seven cases of biopsy-proven eosinophilic cystitis seen over an 8-year period were evaluated retrospectively. All of the five men and two women had symptoms of dysuria and frequency, with haematuria in two cases. One developed acute painful retention. The urine was sterile in all. Radiological findings included bladder mass lesions and upper tract dilatation. Cystoscopy showed papillary, erythematous and ulcerative mucosal lesions, and in one instance a large mass lesion. The various procedures carried out were cold cup biopsies, transurethral resections, or fulgration of lesions and partial cystectomy. Medical therapy included non-steroidal anti-inflammatory drugs and prophylactic antibiotics to cover the procedures carried out. There was excellent symptomatic improvement in all patients. This is the largest single-centre experience reported, and is unusual as the majority of the patients in this series were men.

The pattern of angiodysplasia of the gastrointestinal tract in a tropical country.

Angiodysplasia of the intestine was diagnosed by selective visceral angiography in ten of 30 patients from India with unexplained recurrent hemorrhage of the gastrointestinal tract. In contrast with the reports from the western literature, most of the instances involved the small intestine and occurred in the third decade of life.
