The antegrade manipulation with stone dislodger was applied in 7 cases of unilateral multiple ureteral calculi or ureteral calculi accompanied with ipsilateral renal calculi who were admitted to the Department of Urology, Korea University Hospital during the period of 3 years and 7 months from August 1975 to March 1979. After surgical operation including pyelolithotomy, partial nephrectomy or ureterolithotomy for removal of proximal calculi, stone dislodger was passed downward to the distal calculi through the opening made in the kidney pelvis or ureter. When loop catheter is used a sufficient length of catheter is passed to ensure placement of the loop segment is in the bladder. When the stone is snared, a slow and gentle withdrawal motion will facilitate extraction. Compared with the cystoscopic manipulation, the antegrade use of stone dislodger had advantages and high success rate. Results and advantages are described below. 1. In six cases among seven, distal stone was extracted successfully with this procedure. 2. Among the six successful cases, one was upper ureteral stone and five were lower ureteral stones. 3. Each case had one distally located stone in the ureter and the largest one among them was 0.7 X 0.9cm in size. 4. No specific complications were noted during or after procedure in all six cases 5. Advantages of the antegrade manipulation were as followings. 1) Calculi which was snared, could be extracted without difficulty or ureteral trauma because the ureter proximal to the calculi was usually dilated. 2) Appropriate control of traction power and easy manipulation could be performed. 3) When loop catheter was used it was safe because the loop was formed in wide space of the urinary bladder. 4) There was no urethral injury. 5) Another surgical procedure or retrograde cystoscopic manipulation for removal of distal calculi was not necessary.

The analysis of urinary calculi is an essential step in the examination and initial treatment of the patient with urolithiasis. Among the various methods of stone analysis, we have used x-ray diffraction method for analyzing urinary calculi. The advantage of x-ray diffraction is its almost absolute identification of crystalline materials and mixtures of crystalline materials. The disadvantage of x-ray diffraction include initial high cost of equipment and inability to identify amorphous materials and constituents present in only minor or trace amounts. We have analyzed 127 urinary calculi by x-ray diffraction method, which were obtained from the patients who were admitted to the Department of Urology, Chosun University Hospital during the period of 5 years from Jan. l98l to Dec. l985. The following results were obtained: 1. In this studies, 8 crystalline components of urinary calculi were demonstrated: Calcium oxalate monohydrate, Calcium oxalate dehydrate, Calcium oxalate trihydrate, Hydroxyl-apatite, Magnesium ammonium phosphate hexahydrate, Calcium hydrogen phosphate dihydrate, Uric acid and Cystine. 2. Calculi of single component, comprising 73 (57.6%) of the total, was more common than those of mixed component, 54 (42.4%) of the total. Calcium oxalate monohydrate was the most common pure calculi, composing 46 (36.2 %) of all pure calculi and mixed calcium oxalate monohydratecalcium oxalate dihydrate calculi was the most common mixed calculi, constituting 20 (15.7%) of all mixed Calculi. 3. Classifying author`s results as Jensen`s classification, pure calcium oxalate and calcium oxalate apatite mixtures composed 87.3% of total, magnesium ammonium phosphate-apatite mixtures constituted 4.O%, uric acid comprised 6.5%. 4. Among the all urinary components analyzed in this studies, calcium oxalate monohydrate was the most common constituent, composing 78% of the total and calcium oxalate dihydrate was the second common constituent, comprising 37.6%, calcium oxalate was the most common component, composing 9l.3% of the total. 5. In the components associated with calcium oxalate monohydrate, calcium oxalate dihydrate was the most common associated component, in calcium oxalate dihydrate calcium oxalate monohydrate, in hydroxyl-apatite calcium oxalate monohydrate, in uric acid calcium oxalate monohydrate 6. According to the distribution of urinary component in each urinary organ, calcium oxalate (esp. calcium oxalate monohydrate exceeded 50%) was the most common component in entire urinary tract, which comprised 59.1% of all renal calculi, 69.4% of all ureteral calculi, 33.3% of all bladder calculi and 100% of all urethral calculi. 7. Of 44 renal calculi, 30 were composed of staghorn calculi, in which calcium oxalate was the most common component, constituting 56.6% of 30 staghorn calculi.

The evaluation of urinary calculi was done in 84 patients of paraplegia and quadriplegia due to traumatic spinal cord injury. These patients were diagnosed by KUB and intravenous urography at National Veterans Hospital during 6 years from Jan. 1975 to Dec. 1980. The results were as follows; 1. Overall incidence of urinary calculi was 38.1 %; Incidence of renal calculi was 8.3%, ureteral calculi 4.8%, and urinary bladder claculi 32.1%. 2.Relation of neurological level and incidence of urinary calculi were as follows; Cervical injury in 34.8% upper thoracic injury in 40.0%, lower thoracic injury in 45.0%, and lumbar injury in 36.5%. 3. Laterality was not toplay a role information of urinary claculi. 4. The urinary calculi were developed 62.5% during the first 36 months following spinal cord injury. 5. The recurrence of urinary calculi was 40.6%; True recurrence was 15.6% and pseudo recurrence was 25.05.

Extracorporeal shock wave lithotripsy (ESWL) has been established as the first line procedure of urinary stone treatment. To evaluate clinical efficacy and to identify the criteria of proper patient selection tempered by understanding of the limitations of the ESWL therapy available. We reviewed 2500 patients with urinary stone treated by ESWL using the Northgate SD-3 lithotriptor between June, 1989 and May, 1995. The results were obtained as follows: 1. The total average success rate of treatment was 92.6%. 2. The success rate according to stone locations were 88% in kidney (1074/1214 cases), 93.5% in ureter(1275/1323 cases) and 92.7% in bladder (38/41 cases). 3. The success rate according to stone size measured on the KUB film were 98.0% below 10mm, 91.0% in 11 - 20mm, 80.0% in 21 - 30mm and 68.7% over 31mm. 4. The average numbers of treatment were 2.3 sessions and the mean number of shock per treatment were 1940 +- 230. 5. Of the 2578 cases, 2178(84.5%) were treated by ESWL monotherapy. For auxiliary procedure, Double-J stents were placed in 64 cases and nephrostomy in 49 cases. Stone manipulation including push back, Dormia basket, Ureteroscopy were performed in 161 cases. We conclude that as a highly effective and minimally invasive treatment modality, ESWL has become to be the therapy of choice in 85.5% of urinary stones. When ESWL therapy is less effective for stone size larger than 3 cm(68.7%), staghorn calculi (65.5%) and presence of anatomical barriers, the additional endourologic procedures need to be indicated.

We attempted to compare the result of EDAP LT-01+ lithotripsy with Modulith SLX lithotripsy for management of urinary stones. We evaluated 1,544 patients (1,731 renal units) treated with EDAP LT-01+ ESWL (Group A) and 668 patients (707 renal units) treated with Modulith SLX ESWL (Group B). The results were obtained as follows; 1. Between the group A and B, stones were located in kidney (except staghorn calculi) in 666 cases (38.5%) and 160 cases (22.6%), in staghorn calculi in 31 cases (1.8%) and 13 cases (1.8%), in ureteropelvic junction (UPJ) in 65 cases (3.8%) and 19 cases (2.7%), in upper ureter in 469 cases (27.0%) and 200 cases (28.3%), in lower ureter in 491 cases (28.4%) and 271 cases (38.3%) and in bladder in 9 cases (0.5%) and 10 cases (1.4%), respectively. 2. Success rates according to stone size were 99.4% and 99.6% in less than 1 cm:, 97.5% and 97.2% in 1 cm2 to 2 cm2, 92.4% and 91.3% in 2 cm2 to 3 cm2 and 82.2% and 78.1% more than 3 cm2 respectively in the group A and B. There. was no statistically significant difference between two groups (,p>0.05). 3. Success rates ccording to stone location were 98.8% and 100% in renal stone (except staghorn calculi) , 83.9% and 84.6% in staghorn calculi,92.3% and 94.7% in UPJ stone, 97.7% and 98.5% in upper ureteral stone, 98.4% and 98.6% in lower ureteral stone and 66.7% and 30% in bladder respectively in the group A and B. There was no statistically significant difference between two groups (p>0.05). 4. Average shock wave sessions and time (min.) were 4.0 and 1.8 and 42.1 and 28.6 respectively in the group A and B. These differences were statistically significant (p<0.05). 5. Complications were gross hematuria (>=3 days) in 1.6% and 10.7%, steinstrasse in 5.1% and 12.5%, fever (>=38 degree C) in 2.1% and 2.3% and perirenal hematoma in 0% and 0.7% respectively in the group A and B. We concluded that success rates according to location and size of urinary stone were similar between two groups. But, treatment time of the group B was significantly shorter than that of the group A. Treatment sessions of the group B were decreased compared with the group A. Gross hematuria and steinstrasse were occurred significantly more in the group B compared to the group A (p<0.05).

PURPOSE: Terpene combination (Rowatinex) is known to help with the expulsion of urinary stones. The aim of this study was to determine how Rowatinex affects the expulsion of remnant stones after shock wave lithotripsy (SWL). MATERIALS AND METHODS: Clinical data were collected retrospectively from 499 patients with a diagnosis of ureteral stones who underwent SWL from January 2009 to August 2012. Ureteral stones were diagnosed in all patients by kidney, ureter, and bladder x-ray and abdominal computed tomography (CT). The progress of patients was documented every 2 weeks to confirm remnant stones after SWL. The patients with remnant stones underwent SWL again. Group 1 consisted of patients who were prescribed an analgesic, Tamsulosin 0.2 mg, and Rowatinex. Group 2 consisted of patients who were prescribed only an analgesic and Tamsulosin 0.2 mg. The expulsion rate of urinary stones was compared between groups. RESULTS: The expulsion rate of urinary stones was not significantly different between the two groups after 2 weeks. However, after 4 weeks, group 1 had a significantly higher expulsion rate (72.2% compared with 61.1%, p=0.022). Fifteen patients (10.2%) in group 1 and 40 (11.4%) in group 2 had to undergo ureteroscopic removal of the stone (p=0.756). Acute pyelonephritis occurred in one patient (0.7%) in group 1 and in one patient (0.3%) in group 2 (p=0.503). CONCLUSIONS: The long-term administration of Rowatinex for 4 weeks increased the expulsion rate of urinary stones after SWL.

A statistical observation was made on 841 cases of urolithiasis among the l.004 cases which were seen during the 15 years period from January 1963 to December. 1977. 1. The incidence of the patients with urolithiasis was 1.85 % of total urological patients and 19.2 % of the inpatients. 2. The incidence of the patients with urolithiasis did not increase in spite of increasing annual incidence of inpatients. 3. They consisted of 266 patients with kidney stone (29 %) . 573 patients with ureter stone (61 %). 68 patients with bladder stone (7%) .and 26 patients with urethral stone (3%) The ratio of upper urinary tract stones to lower urinary tract stones was 9 to I. Among the 266 cases of the kidney stone, 21 cases were staghorn calculi. 4. The most favored predilection of ureter stones was lower 1/3 of ureter in 61% of these. 5. Seasonal variation of urolithiasis was not distinct, but the summer was the most favored season. 6. They were most commonly found between the ages of 20 to 50 (82 %). The causes were not found in all cases of childhood urolithiasis ( 8 cases) under the ages of 10. 7. The ratio of males to females was 2.7 to 1, however, the staghorn calculi were more commonly found in female. The ratio of males to females under age of 25 years was 1.8 to 1. 8. The upper urinary tract calculi occurred both in the right and left side with approximately equal frequency. 9. Multilocated stones were found in 10.7 % of all cases and bilateral stones were found in the 8.4% of the all cases. 10. The clinical symptoms of upper urinary tract calculi were flank pain in 85%, hematuria in 27.7 %, frequency in 17.8 %, nausea and vomiting in 10.4 %, and fever in 7.2%. The clinical symptoms of lower urinary tract calculi were painful urination in 78.7%, frequency in 48.8%, hematuria in 33%, and sudden stoppage in 33%. 11.

A clinical evaluation was done on Il patients with postrenal acute renal failure who were admitted to the Busan National University Hospital during the period of 6 years and 8 months from Jan. 1976 to Aug. 1982. The results were as follow. 1. The patients were mean ages of 44.3 years, being thought somewhat older than other cause of renal failure. And the male was more frequently affected than the female. 2. The 2 most common causes of postrenal acute renal failure in 11 patients were malignant neoplasms (5 patients; 1 bladder Ca. 3 cervical Ca. and 1 retroperitoneal metastatic Ca.) and ureteral calculi (5 patients; 2 bilateral and 3 unilateral in solitary renal unit). 3. Ureteral obstructions were bilateral in 7 patients (14 ureters) and unilateral in 4 patients (4 ureters) in the solitary kidney. The involved site of ureteral obstructions were bilateral lower ureters in 5 patients (10 ureters), bilateral upper ureters in 1 patient (2 ureters), unilateral right upper ureter and left lower ureter in 1 patient 12 ureteral, and unilateral lower ureter in 4 patients (4 ureter). 4. Seven patients were treated with urinary diversion, 3 with ureteral catheterization and 1 with ureterolithotomy. Among 7 patients of urinary diversion, nephrotomy was done in 6 patients and double-barreled ureterocutaneostomy in 1 patient. 5. The prognosis was excellent in 10 patients and 1 patient was expired due to uremia and generalized marasmus following malignant neoplasm.
