A stone developed within the dilated intravesical ureter following ureteroscopy.

A 58-year-old man presented with a stone within the dilated intravesical ureter, which was probably attributable to a previous ureteroscopy. Transurethral incision of the right intravesical ureter and lithotripsy were carried out without subsequent urinary tract impairment. Although some complications resulting from ureteroscopy, such as ureteral stricture, ureteral perforation and vesicoureteral reflux, have been reported, this complication is considered to be very rare.

[Availability of NMP22 (nuclear matrix protein 22) for the diagnosis of urothelial cancer].

We evaluated the availability of NMP22 for the diagnosis of urothelial cancer. Of 154 patients with gross hematuria or microscopic hematuria, 14 patients with bladder cancer and 4 patients with upper urothelial cancer were detected. Of 73 patients continued to be followed for urothelial cancers, 11 patients with bladder cancer were detected. NMP22 was not available when a large number of RBC was present in urine. Also, NMP22 was significantly higher in patients with urothelial cancers. Interpretation of the ROC curve indicated an optimal cutoff value of 9.2 u/ml. Using 9.2 u/ml as a cutoff, the sensitivity and specificity were, respectively 87.0% and 64.0% in patients with hematuria, and 81.8% and 78.7% in patients with a history of TCC. This indicated that when NMP22 was used for the diagnosis of urothelial cancers, 12.0 u/ml, the value recommended as a cutoff in Japan, might be too high to differentiate patients with urothelial cancers.

[Small cell carcinoma of the urinary bladder: a case report].

We report a case of small cell carcinoma of the urinary bladder. A 60-year-old man with microscopic hematuria was referred to our hospital. Cystoscopy revealed a sessile tumor on the left lateral wall of the urinary bladder. The patient underwent transurethral resection of the bladder tumor (TUR-Bt). Because of muscle invasion (pT2), total cystectomy was recommended, but was not performed because the patient would not give consent for the operation. Six months after TUR-Bt, invasive bladder tumor recurred and total cystectomy was performed. Pathological examination of the operative specimen revealed small cell carcinoma. Adjuvant combined therapy of irradiation and chemotherapy (nedaplatin and etoposide) was ineffective. Metastases to retroperitoneal lymph nodes, lung and liver were detected soon after the adjuvant therapy. The patient died 15 months after his first visit to our hospital.

[Clinical statistics at the urological clinic of Sanjukai Hospital--statistics on new outpatients over the last five years].

We herein report the clinical statistics on new outpatients over five years from 1994 at our hospital. The average number of new outpatients per year was 8,534.4 (8,366-8,658) and there was only a slight variation in the number over the last five years. The male to female ratio was 1.61:1. Twenty-one percent of the outpatients were referred to us by other sources. The representative operations on outpatients were circumcision, vasectomy, resection of condylomas and resection of caruncles. A statistical study was made on new outpatients according to the international classification of disease. There were 197.0 (2.3%) malignant urogenital tumors per year. There was a tendency for sexually transmitted diseases to increase over the last five years. In males, the major diseases were upper urinary tract stones (23-27%), benign prostatic hypertrophy (19-26%) and prostatitis (15-24%). In females, they were cystitis (57-59%), upper urinary tract stones (17-18%) and neurogenic bladder (3-4%). We conclude that our hospital plays a major role as a private urological hospital.

Effect of oral administration of prostaglandin E1 on erectile dysfunction.

OBJECTIVES: To investigate the effect of limaprost, an oral prostaglandin E1 (PGE1) derivative, on erectile dysfunction and to compare the effects of limaprost with a Chinese herbal drug, gosyajinki-gan. PATIENTS AND METHODS: The study comprised 50 consecutive patients with mild erectile dysfunction who showed a good erectile response to intracavernosal injection with 20 micrograms of PGE1. Limaprost was administered to the first 25 patients (30 micrograms three times daily) and gosyajinki-gan (7.5 g three times daily) to the next 25 patients, for 8 consecutive weeks. Patients were evaluated by their ability to achieve vaginal penetration and by a subjective assessment of erectile function (penile rigidity and maintenance of erection) before and after the treatment, using a self-administered questionnaire. Objective measurements (nocturnal penile tumescence, NPT, values) were also evaluated. RESULTS: Eleven of the 24 patients who received limaprost without interruption and four of the 24 taking gosyajinki-gan succeeded in vaginal penetration; the difference in the positive response rate was significant. The mean increment of NPT was significantly higher with limaprost treatment. However, all positive responders in both groups did not experience a full erection. There were no side-effects in any patient except one in the limaprost group who developed a facial flush. Thus the treatment was mild enough to be tolerated. CONCLUSION: Limaprost was more effective for mild erectile dysfunction than was gosyajinki-gan.

[Clinical outcome of percutaneous nephrolithotripsy and recurrence of stones].

A total of 178 renal units in 173 patients with renal and upper ureteral calculi were treated by percutaneous nephrolithotripsy (PNL) between November 1984 and October 1995. PNL was performed as a monotherapy in 70 kidneys, while extracorporeal shock wave lithotripsy (ESWL) was combined in 108 kidneys. At the time discharged 110 (61.8%) kidneys were stone-free and the overall success rate, defined as no residual stone or fragments < 4 mm, was 96.1%. The stone-free rate was significantly lower (44.2%) for staghorn renal calculi. For 105 stone-free kidneys with > 6 months of follow-up, the cumulative stone recurrence rate was 4.2% at 1 year, 16.6% at 3 years, 29.2% at 5 years, 34.4% at 5 years and 55.4% at 10 years. None of the pretreatment parameters, such as stone size, number, location, composition, past history of urolithiasis and upper urinary tract obstruction, had a significant influence on stone recurrence.

[Recurrence of stones after extracorporeal shock wave lithotripsy].

During the 11-year period from September 1984 through August 1995, extracorporeal shock wave lithotripsy (ESWL) was performed on 5,558 patients using a Dornier HM3 apparatus. A recurrence questionnaire was sent out to 2,379 of those who had had complete elimination of the calculi and for whom at least 3 years had passed since the ESWL. The last day of follow-up was defined as follows: the day of completion of the questionnaire in the recurrence-free group (n = 787), the day when recurrence of calculi was diagnosed in the recurrence group (n = 415) and the day of the last visit to the outpatient clinic in the miscellaneous group (n = 1,133). The cumulative recurrence rates were calculated by the Kaplan-Meier equation. The resultant data were analyzed for statistically significant differences by the log rank test and the generalized Wilcoxon test. Ap value of < or = 0.05 was considered to indicate significance. The recurrence rate was examined for differences in relation to the following risk factors: the patients' age and sex, the stone location, size and number, the presence or absence of past history of lithiasis, the composition of the stone (s), and the presence or absence of urinary tract complications. The cumulative recurrence rates for the total cases were 2.0% at one year, 13.1% at 3 years, 23.9% at 5 years, 30.7% at 7 years and 40.7% at 10 years. Significantly higher recurrence rates were found for patients under 60 years of age, those with multiple stones and those with a past history of disease.

[A study on the erectile response with the vacuum constriction device compared with intracavernous injection of a vasoactive drug].

Many types of vacuum constriction devices (VCDs) are used for the treatment of impotence, but the VCDs made in the USA are too large for Japanese males, and air leakage occurs. Therefore, we examined the erectile response of 47 impotent men to a vacuum constriction device that is made in Japan and can be applied suitably for Japanese men, and compared the response to intracavernous injection of prostaglandin E1 (PGE1). When the 47 cases were divided into two groups by nocturnal penile tumescence, twenty of the impotent men were regarded to have fewer organic factor (group A) while 27 were regarded to have more organic factor (group B). All (100%) of the 20 cases of group A achieved a complete erection with the VCD, but only 11 (55%) of them achieved a complete erection with PGE1. Twenty-three (85%) of the 27 cases of group B achieved a complete erection with the VCD, but only nine (33%) achieved a complete erection with PGE1. Two of the four patients who did not achieve a complete erection with the VCD stopped pumping the VCD because of penile pain, and the other two patients had a penile-brachial pressure index (PBPI) of under 0.65. It was suggested that patients with no severe vascular disease can show a good erectile response with the VCD.

[Clinical statistics at the urological clinic of Sanjukai Hospital--statistics on new outpatients during the last five years].

We report the clinical statistics of new outpatients for five years since 1989 at our hospital. The average total number of new outpatients in a year was 8309.8 (8122-8691) and new outpatients tended to show little change. The male to female ratio was 1.57:1, and 24.3% of the outpatients were referred to us by others sources. The representative operations on outpatients were circumcision, vasectomy, resection of condyloma and resection of caruncle. A statistical study was made on new outpatients according to the international classification of disease. There were 140.6 (1.97%) malignant urogenital tumors per year. Sexually transmitted diseases showed a tendency to increase for the last five years. In males the major disease was upper urinary tract stone (21-24%), prostatistis (21-24%) and benign prostatic hypertrophy (17-20%) and in females they were cystitis (58-61%), upper urinary tract stone (15-17%) and pyelonephritis (3-4%). We conclude that our hospital plays a major role as a private urological hospital.

[Endoscopic correction of vesicoureteral reflux by Teflon].

From March 1988, 19 vesicoureteral reflux (VUR) patients were treated by endoscopic injection of Teflon paste. Of these patients 17 cases 27 ureters were followed for more than one year. After injection of Teflon paste, reflux was eliminated in 63%, decreased in 30%, and unchanged in 7%. Then 7 ureters were injected twice and 1 ureter three times. Finally, reflux was eliminated in 93% of all cases, and decreased in 7%. Early complications were fever up in 4 cases, flank pain 3, acute cystitis 1. In the follow up period, acute cystitis occurred in 1 patient, ureter stone in 1, and renal failure in 1. However, the ureter stone and renal failure were probably not caused by this procedure.

[Clinical statistics of the Urological Clinic of Sapporo Sanjukai Hospital. Clinical statistics on patients admitted from 1985 to 1989].

A clinical statistic survey was carried out on the patient admitted, diseases and operations experienced at our urological clinic during 1985-1989. The total number of inpatients was 8,750 (The male to female ratio was 2.8:1). The major diseases of the inpatients were urolithiasis (4,134 cases, 47.2%) and benign prostatic hypertrophy (1,529 cases, 17.5%). Among the operations extracorporeal shock-wave lithotripsy 2,589 cases (44.6%) and transurethral resection of prostate 1,295 cases (22.3%) were predominant.

[Clinical application of Modulith SL20 on extracorporeal shock wave lithotripsy for upper urinary tract calculi].

Thirty-nine patients, 27 males and 12 females with renal and ureteral stones, were treated using the Modulith SL 20 between October 1990 and January 1991. Thirty-three of the 39 cases had a single session of extracorporeal shockwave lithotripsy (ESWL) and the other six cases had two sessions. The pulverization rate of ESWL by this device was 84.6%. According to the X-rays taken 21 days after ESWL, of the 37 cases, 14 (37.8%) were stone-free, 18 (48.7%) had residual sandy stones less than 4 mm in diameter, five (13.5%) had residual stone fragments larger than 4.1 mm in diameter, and two cases were not clear. Using the criterion of cases which can be expected to have spontaneous passage, in other words, residual stones less than 4 mm in diameter, lithotripsy with the Modulith SL 20 was regarded as "effective" in 32 of the 37 cases (86.5%). As side effects of this treatment, hematuria was observed for several days after ESWL in all patients, but not other serious complications were observed. Among the 37 cases in which the grade could be evaluated the evaluation for 24 (64.9%) was "useful" and that for 13 (35.1%) "useful to some extent". Therefore, ESWL was performed very successfully.

[Studies on incidental carcinoma of the prostate].

We reviewed 157 patients retrospectively with incidental carcinoma of the prostate who had been treated at our collaborating hospitals during the past ten years. Of 5212 patients with benign prostatic hyperplasia who received subcapsular prostatectomy or transurethral resection of the prostate (TUR-P), 157 (3.0%) were diagnosed as having an incidental carcinoma of the prostate, which was somewhat lower than that in previously published reports. Of these, 30 and 127 patients were in stage A1 and A2, respectively. Well, moderately and poorly differentiated carcinomas were found in 44.6%, 36.7% and 18.5% of the patients, respectively. The incidence of poorly differentiated carcinoma in the study seemed to be higher than that in the previous reports. A positive correlation was identified in TUR-P specimens between the carcinoma differentiation and its extension which was evaluated by cancer-positive chip ratio. Atypical adenomatous hyperplasia and intraductal dysplasia were identified in 36.9% and 85.3% of the patients with incidental carcinoma, respectively. These incidences tended to become lower as the carcinoma became less differentiated or more extended. Further studies will be necessary to define the significance of these pathological findings as a direct biological precursor of prostatic carcinoma. Six out of the 157 patients with incidental carcinoma showed a progression during the follow-up period. All of these patients were in stage A2 and all but one showed a histology of moderately or poorly differentiated carcinoma at the time of diagnosis. Radical prostatectomy or radiation therapy as well as endocrine therapy should be considered as treatment modalities for stage A2 patients, when staging lymphadenectomy shows no pelvic lymph node metastasis.

[Clinical study on recurrence of urinary tract lithiasis of ESWL].

During the 4 year period from September 1, 1984 through August 31, 1988, a total of 1,866 patients with calculi of the urinary tract (125 patients had bilateral calculi) were subjected to extracorporeal shock wave lithotripsy (ESWL) with a DORNIER HM3 ESWL apparatus. Follow-up was performed factor 1,056 cases 3 or more months after complete elimination of the calculi, and data were obtained for 343 of them. Lithiasis was found to have recurred after ESWL in 30 cases, with a recurrence rate of 11.1%. Recurrence was seen in 16.9% of cases with multiple calculi and 6.5% of cases with a single calculus. The difference was statistically significant. Surgical removed of calculi or spontaneous discharge of calculi had been experienced in 50.0% of the recurrent cases and 27.8% of the non recurrent cases. The difference was also statistically significant. Stone size, stone location and urinary tract infection were unrelated to the recurrence.

[Effects of anti-androgens on sexual function. Double-blind comparative studies on allylestrenol and chlormadinone acetate Part I: Nocturnal penile tumescence monitoring].

Allylestrenol (ALE) and chlormadinone acetate (CMA) were administered to patients with prostatomegaly by the double-blind method, and the effects of these antiandrogens on their sexual function were objectively compared. Each agent was orally administered to 58 patients in a dosage of 50 mg/day for 12 consecutive weeks. For the objective evaluation of the sexual function, nocturnal penil tumescence (NPT) was measured using an erectometer. For the subjective evaluation the conventional interview method was employed. The levels of hormones relating to sexual function were also determined. A decrease in NPT was noted in both the ALE and CMA groups, but the degree of the decrease was significantly smaller in the ALE group than in the CMA group (p less than 0.001). The results of the interview, revealed a large between the two drug groups; in the CMA group, marked worsening for all items. In the determination of hormones, levels of luteinizing hormone, follicle stimulating hormone, testosterone and estradiol were decreased in both drug groups, while the prolactin level was increased in both groups. The changes in the testosterone, estradiol and prolactin levels in the CMA group were significantly dominant compared with those in the ALE group. In addition, drop-out cases due to a decrease in the sexual function numbered 7 (12.1%) in the CMA group, while there were no such drop-out cases in the ALE group; the difference in the drop-out rate was thus significant. In conclusion, ALE's effects on the sexual function were concluded to be smaller than those of CMA.

[Effects of anti-androgens on sexual function. Double-blind comparative studies on allylestrenol and chlormadinone acetate. Part II: Self-assessment questionnaire method].

Allylestrenol (ALE) and chlormadinone acetate (CMA) were administered to patients with prostatomegaly by the double-blind method, and a self-assessment questionnaire method developed by the authors was used to study the influence of these two antiandrogens on their sexual function. Each test drug was orally administered to 58 patients, in a daily dosage of 50 mg for 12 consecutive weeks. The questionnaires consisted of 6 categories each consisting of 5 questions, or 30 questions in total. The 6 categories were "sexual desire," "erectile capacity" and "ejaculation," which relate to the sexual function, and "living environment (including the frequency of sex)," "dysuria" and "dummy (personality)." Each question was graded into 0-10 points, and each patient was requested to circle the number which best described his status. The scores were compiled and statistically analyzed. Many patients were senile. Evaluable answers were obtained for 99 (85.3%) of the 116 patients. Factor analysis based on the preadministration scores confirmed the contents of the questionnaires to be appropriate for the objectives of the present study. Multiple regression analysis revealed a high correlation between the self-assessment scores and objective data (nocturnal penile tumescence values; NPT values) when dropout cases due to a decrease in the sexual function and non-replying cases were excluded. The self-assessment questionnaire method was concluded to be as useful an objective test method as the NPT measurement for examining the sexual function. Aggravation of the "frequency of urination during night" was conspicuous in the CMA group, and there was a significant difference (p less than 0.05) in this parameter between the two groups. Except for this parameter, dysuria was improved in both administration groups, and there was no significant difference in the efficacy of the two drugs. Both drugs tended to suppress overall sexual function, but the suppression was less severe in the ALE group. Especially the suppression was significantly (p less than 0.05) lower in the ALE group regarding the 3 parameters of "contact sexual arousal," "contact erection" and "morning erection", which are included in the category of "sexual desire" or "erectile capacity." Also, suppression of "frequency of sex" and "intensity of sexual desire" tended to be lower in the ALE group at a level of significance of p less than 0.1. Regarding questions in the category of "ejaculation," the incidence of non-replies was high in both groups, but its rate was higher in the CMA group.
