Abstract

PURPOSE: The parameters responsible for proximal ureteral stent migration were quantitated. MATERIALS AND METHODS: We compared 16 patients seen between 1990 and 1993 with stent migration to 32 patients whose stents did not migrate. RESULTS: The stent indwelling time and number of stents with a proximal curl of less than 180 degrees were similar between the groups. More patients with migration had stents that were shorter than the ideal length, with a distal curl of less than 180 degrees and a proximal curl in the upper calix versus the renal pelvis. CONCLUSIONS: A shorter than ideal stent, inadequate distal curl and a proximal curl in the upper calix appear to be significant factors in the process of stent migration.

Correlation between the International Prostatic Symptom Score and a pressure-flow study in the evaluation of symptomatic benign prostatic hyperplasia.

PURPOSE: We examined the relationship between the International Prostatic Symptom Score (I-PSS) and the occurrence of bladder outlet obstruction caused by benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: The American Urological Association developed a questionnaire to quantify the severity of symptoms resulting from BPH. A further question relating the impact of BPH to the quality of life was subsequently added. This questionnaire has been adopted by the World Health Organization and is known as the I-PSS. There are 4 questions related to obstructive symptoms and 3 related to irritative symptoms. Scores of 0 to 7, 8 to 19 and 20 to 35 represent mild, moderate and severe symptoms, respectively. During an 18-month interval the I-PSS questionnaire was administered to 258 patients 50 to 81 years old (mean age 63 years) with BPH. A pressure-flow study was used to determine the presence of bladder outlet obstruction in 227 patients. Based on the scores, the patients were divided into 31 with mild, 116 with moderate and 111 with severe obstruction. The pressure-flow study was not conducted on patients with a mild symptom score. RESULTS: Of the patients with a severe symptom score 92 (82.9%) had bladder outlet obstruction, compared to 62 (53.4%) with a moderate symptom score. Statistical analysis (Pearson chi-square test) showed that there was a significant positive correlation between the symptoms and the presence of bladder outlet obstruction. Thus, when the I-PSS was greater than 28, the probability of bladder outlet obstruction was more than 0.91. Stratification of the results according to the obstructive (0 to 20) and irritative (0 to 15) symptoms of the I-PSS yielded a significant positive correlation between obstructive symptoms and the presence of bladder outlet obstruction. Thus, when the obstructive symptom score was greater than 15, the probability of bladder outlet obstruction was greater than 0.91. CONCLUSIONS: When the total I-PSS is greater than 28 or the obstructive symptom score is greater than 15, a pressure-flow study must be avoided.

Ultrasonographic characteristics of testicular adenomatoid tumors.

PURPOSE: We determined the characteristics of testicular adenomatoid tumors which could distinguish these lesions from testicular malignancies. MATERIALS AND METHODS: Clinical presentation and ultrasonographic findings in 3 men with testicular adenomatoid tumors were compared with those in 10 men treated for testicular malignancies. RESULTS: Clinical presentation was similar for all patients. Of the 3 adenomatoid tumors 2 appeared isoechoic on ultrasound and 1 appeared normal. None of the 10 cancers appeared isoechoic or normal on ultrasound. CONCLUSIONS: Small tumors that appear isoechoic on ultrasound should be biopsied through an inguinal incision with frozen section assessment rather than immediate radical orchiectomy.

Urinary calculi as a late complication of the Indiana continent urinary diversion: comparison with the Kock pouch procedure.

PURPOSE: Although urinary calculi have been frequent late complications of the Kock continent urinary diversion, they have not been regarded as significant problems in patients with the Indiana pouch because of the lack of foreign material present. However, stones developed in a significant percentage of our patients with an Indiana pouch. We investigated the characteristics of stone formation in patients with the Indiana pouch and compared them to those with a Kock pouch. MATERIALS AND METHODS: Detailed clinical courses regarding stone formation were reviewed in 72 patients with a Kock pouch and 54 with an Indiana pouch who had a minimum followup of 12 months. RESULTS: Stones developed in 7 of 54 patients (12.9%) with an Indiana pouch compared to 31 of 72 (43.1%) with a Kock pouch. The incidence gradually increased with longer followup but it was lower in the Indiana than in the Kock pouch group (5-year stone-free rate 84% versus 66%, respectively). Although the stones consisted principally of a mixture of struvite, carbonate apatite and ammonium hydrogen urate, variable amounts of calcium oxalate were identified in 50% of the Indiana pouch calculi. CONCLUSIONS: Not only urinary infections but also metabolic factors were considered to be involved in stone formation within the Indiana pouch. However, the substantially higher rate of stone formation in our Kock and Indiana pouch groups than has been reported in the United States suggested that no or infrequent pouch irrigations in our patients were important risk factors for urinary calculi.
