The effect of combining therapy with hydrochlorothiazide, allopurinol and systemic alkalization for urolithiasis with lower urinary pH was examined. A total of 90 patients were followed up for 1 to 3 years, the average follow up period being 18 months. The total stone disappearance rate was 60% (kidney stone), 74% (ureter stone) and 20% (bladder stone). Large amounts of thiazide diuretics, potassium and magnesium were intravenously administered to a patient with systemic alkalization at slow infusion speed, neither serious side effects nor complication occurred. This method is simple and an effective remedy. It is also very practical in the developing countries of the third world.

Extracorporeal shock wave lithotripsy was performed on 81 patients with urolithiasis (35 patients with ureteral stones, 25 patients with renal stones less than 2 cm in diameter, and 21 patients with renal stones more than 2 cm in diameter) at Kanbara Hospital from August to October, 1986. A 4 Fr catheter was placed transurethrally in the ureter up to the stone to identify the stone position and the degree of fragmented stones. In four patients with staghorn calculi, a double-J catheter was placed in the ureter to prevent stone street formation. More than 50% of the patients with renal stones less than 2 cm in maximum diameter and ureteral stones had satisfactorily excreted fragments or sand of crushed stones not later than 2 weeks after the operation. However, in patients with renal stones more than 2 cm in maximum diameter, it took much more time to discharge the crushed stones compared with the foregoing two groups and some patients needed further management to remove the remnants. Combined treatment, ureteral catheterization or endoscopic operation with ESWL is recommended for treatment of renal stones larger than 2 cm in diameter.

The statistics of urological operations performed at our department between Jan., 1, 1982 and Dec., 31, 1986 were reviewed. During the 5 year period, 2331 patients were admitted to our hospital and 2192 urological operations were performed on 1834 patients. These statistics were compared with earlier statistics for two periods (1972-1976 and 1977-1981) and the recent trend of urological operations was investigated. With regard to operated organ, operations on the kidney were the most frequent followed by those on the urinary bladder. Operations on the ureter decreased during the recent 5 year period and they were the fourth most frequent following those on the scrotum, scrotal contents and penis. Operations on the adrenal gland, retroperitoneal space and parathyroid gland have gradually increased. As in the former report, transurethral resection of bladder tumor (TUR-Bt) was the most frequent and nephrectomy, TUR of prostate (TUR-P) and renal allotransplantation have followed. TUR-Bt and TUR-P have increased more and more and due to the introduction of percutaneous nephrolithotripsy and transureteral lithotripsy, open surgery for urolithiasis has greatly decreased. Endourological operations will still be on the increase.

Extracorporeal shock wave lithotripsy was used for the treatment of 1,252 kidneys and ureters with calculi during a 10-month period at the authors' medical center. Before lithotripsy was performed, excretory urography, radiography, renography, computed tomography, and ultrasound studies were done, when necessary, to locate the calculi. Nine calculi in five kidneys could not be fragmented with lithotripsy. Of 895 patients with calculi less than 2.5 cm in diameter, only 13 (1.5%) required interventional procedures to clear the calculi, whereas of 161 patients with calculi greater than or equal to 2.5 cm, 36 (22.4%) required nephrostomies. A column of calculous debris in the mid and distal portions of the ureter (steinstrasse) was seen in 171 instances (13.6%) after lithotripsy; 62% required interventions. The most common intervention required for successful lithotripsy was retrograde ureteral catheterization. Evaluation and treatment of patients with urolithiasis were largely dependent on radiography and excretory urography.

The Piezolith 2200 allows not only a qualitatively identical treatment of urolithiasis like the HM-Dornier systems or the Siemens Lithostar, but the application of lithotriptable urinary calculi could be extended to cardiac risk patients, to patients with skeletal deformities and to those with unusual body height and weight. As the piezolithotripsy does not cause pain, treatment is possible without anaesthesia or analgesia. Combined with internal ureteral stenting by self-retaining double-J-ureteral catheter also calculi with larger stone masses can be treated advantageously by exclusive piezolithotripsy as monotherapy. Multiple treatments by the piezolithotriptor are possible because of good focussing of the shock waves and the smaller parenchymal alteration. Lithotripsy of ureteral calculi is performed in the upper and lower part of the ureter. In small calculi the retrograde introduction of an ureteral catheter armed with an "ultrasound mirror" is necessary.

To evaluate the effect of a tissue adhesive agent (BI 0.022) on renal pelvic and ureteral surgery, the adhesive was applied for 44 patients with urolithiasis. The conventional suture method was performed in 87 patients as a control. The tissue adhesive is composed of fibrinogen, thrombin, factor XIII, aprotinin and CaCl2. The number of sutures for closure of the incision made on the rental pelvis and the ureter was significantly reduced by the use of the tissue adhesive (p less than 0.01). There was no tendency of increase in urinary leakage following the application of the method in comparison with the control. Furthermore, it was noteworthy that 10 in cases with less than a 1 cm ureteral incision were completely closed by the use of the adhesive agent. This tissue adhesive agent should be valuable for renal pelvic and ureteral surgery as a simple substitute for the conventional suture method.

Thirty-two cases of urolithiasis in the lower ureter, difficult to detect by ordinary X-ray studies, were diagnosed accurately by ultrasound. Stonelike echoes were easily detected on the ultrasonograms when the ureter of the affected side was dilated. Patients should be examined by ultrasound prior to invasive retrograde pyelography.

A case of long ureteral polyp with ureteropelvic junction obstruction in a 29-year-old man is reported. He had complained of occasional left flank pain since several years earlier. Excretory urography showed left giant hydronephrosis and no urolithiasis. Retrograde pyelography revealed a mass lesion of the left upper ureter. At exploration, the left ureteropelvic junction was found to be obstructed by an aberrant lower pole renal vessel. At just distal of the junction, a finger-like ureteral polyp, 5 cm in maximal length, was present and accompanied with several little polyps. Partial ureterectomy and pyeloplasty improved the left hydronephrosis. The patient remains symptomless for one year after the operation.

We report about a case with simulated recurrent urolithiasis. The patient introduced foreign bodies (gypsum) into the bladder. Often the stones had to be removed from the bladder and the right refluxing ureter. The diagnosis of the foreign bodies was made after 2 years of malingering by X-ray diffraction (analysis: gypsum = CaSO4 . 2 H2O).

Statistical observations of 19,678 outpatients and 2,601 inpatients at our department from 1975 to 1982 revealed the following results. The new cases in the outpatient clinic were in decreasing order nonspecific infections (50.8%), urogenital tumors (11.9%), urolithiasis (9.3%) and urogenital anomalies (8.0%). The inpatients according to the organ were in decreasing order kidney (29.6%), prostate (25.5%), bladder (13.4%) and ureter (11.9%). Operations were performed 2,414 times. Frequent operations were in decreasing order phimosectomy (360 times, 14.9%), TUR-Bt (284 times, 11.8%), transurethral cryosurgery of the prostate (215 times, 8.9%), vasectomy (190 times, 7.9%) and orchiopexy (152 times, 6.3%). More young persons comprised the outpatients of our hospital than at other facilities.
