PURPOSE: Extracorporeal shock wave lithotripsy (SWL) has been established as the treatment of choice for the urinary stones. But, for the treatment of staghorn calculi, the efficacy of this therapeutic procedure is controversal. We intended to study the therapeutic results and the usefulness of ureteral stent between 2 types of lithotriptor, EDAP LT-01 and Storz Modulith SLX. MATERIALS AND METHODS: Sixty cases were diagnosed as staghorn calculi from February 1990 to December 1998. Among them, 31 patients were treated with EDAP LT-01 SWL (group A) and 29 patients with Storz Modulith SLX SWL (group B). We inserted a double-J stent in 45 patients that consisted of 24 patients from group A and 21 patients from group B. The number of treatment sessions, complications and success rates were compared regarding each SWL and volume of the stone. RESULTS: The success rates of each SWL were 70.9% in group A and 75.9% in group B. The success rates, according to staghorn morphology, were 71.4% and 85.7% in partial staghorn of group A and B. The average shock wave sessions were 12.0 and 7.4 in partial staghorn of group A and B. The success rates, according to staghorn volume, were 67.8% and 88.9% in less than 60cm3 of group A and B. The average shock wave sessions were 12.6 and 9.6 in less than 60cm3 of group A and B. The findings were statistically significant between the two groups in less than 60cm3 or partial staghorn. After SWL, incidence of steinstrasse was 12.5% and 33.3% in the double-J stent inserted patients of group A and B. CONCLUSIONS: SWL could be a method of primary treatment for staghorn calculi. Storz Modulith SLX SWL was more effective than EDAP LT-01 SWL for staghorn calculi of which the volume was less than 60cm3. Placement of ureteral stents would be effective in the treatment of staghorn calculi by EDAP LT-01 SWL and not in Storz Modulith SLX.

2.Clinical experience with EDAP LT-01+ extracorporeal shock wave lithotripsy in 25 staghorn calculi.
Korean Journal of Urology 1992;33(4):659-665
From February 8. 1990 to November 30, 1991, 25 patients with staghorn calculi were underwent extracorporeal shock wave lithotripsy(ESWL) using the EDAP LT-01 lithotriptor. We reviewed patients with staghorn calculi to evaluate the effectiveness of ESWL as monotherapy for staghorn calculi and determine the selection criteria for the treatment calculi. The results were obtained as follows : l. Ten patients had complete staghorn calculi filling the complete renal collecting system with stone of l7,635 mm3 in mean volume and l3 patients had partial staghorn calculi filling the renal pelvis and partial caliceal groups with stone of 7,017 mm3 in mean volume. 2. Of 17 patients with stone of less than 8,200 mm3 in volume. 10(83.3%)remained free of stone after an average 11.8 sessions. Of 6 patients with stone of between 8,200 to 14,200 mm3 volume, 5(83.3%) remained free of stone after an average 18.3 sessions. Of 7 patients with stone of more than l4,200 mm3 in volume, 2(28.6%) remained free of stone after an average 17.4 sessions 3. When these patients were stratified by stone burden, of 10 patients with stone filling a non-dilated renal collecting system, all(100%) patients remained free of stone. Of 15 patients with filling a dilated renal collecting system. 7 (46.7%) patients remained free of stone. Of 8 cases with residual stones. 2 patients were underwent open surgery(nephrectomy, extended pyelolithotomy), 2 patients were impossible to follow up and 4 patients still are undergoing continuous additional ESWL sessions. 5. Double J stent for the pre-ESWL additional measures were placed in 19 patients(76%); Eight of the complete staghorn calculi and 11 of the partial staghorn calculi. Percutaneous nephrostomy tube was placed in 2 patients. No general or regional anesthesia was required. 6. The post-ESWL complications were ureteral obstruction(steinstrasse) in 7 patients(28%) and high fever(over 38.5 degrees C) in 11 patients( 44.0%). We conclude that partial staghorn calculi, staghorn calculi with stone of less than 14,200 mm3 in volume and staghorn calculi with stone burden filling non-dilated collecting system are eligible for ESWL.

3.Comparative study on results between urine flow cytometric DNA analysis and urine cytology in transtional cell carcinoma of bladder.
Korean Journal of Urology 1991;32(6):877-882
We compared the roles of urinary cytology and flow cytometric DNA analysis in the evaluation of 26 patients with transitionsl cell carcinoma of bladder from March 1989 to April 1991. When carcinoma was present at the time of specimen collection it was detected by cytology in 65.4 percent and flow cytometric DNA analysis in 73.1 percent. Combination of flow cytemetric DNA analysis and urinary cytology increased the diagnostic yield to 88.5 percent Flow cytometric DNA analysis was slightly more sensitive than urinary cytology for the detection of abnormalities in specimen from low stage. high grade. small size. small number and recurrent cancer but no statistically significant difference was identified. When used in conjunction with urinary cytology. urine flow cytometric DNA analysis was valuable procedure in the diagnosis and follow up of patients with bladder cancer.

Trauma is the important cause of death in children and adults. From May 1, 1984 to June 30, 1995, 370 patients were admitted to our hospital for genitourinary injuries. We made clinical observations and compared children with adults on incidence, cause, diagnosis and treatment of genitourinary traumatic patients. As the result, it was no significant difference between children and adults on incidence, sex ratio, cause, hospital stay, and associated injuries. The kidney was the most common organ to be injured and there was no difference in severity of renal injury between two groups. Operative treatments were more common in adults than children, and external genitalia was most common organ to get operation.

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).

Korean Journal of Urology 2001;42(3):350-355
PURPOSE: Some authors noted unilateral testicular torsion often leading to a damage in the contralateral testis. But it is not known whether this is the result of an intrinsic abnormality in the remaining testis or testicular injury associated with the ischemic event. Recently some authors noted an increase in germ cell apoptosis in the contralateral testis and suggested the involvement of nitric oxide (NO) in the apoptosis of germ cells. We aimed at the NO involvement in testicular torsion in this study, in which we measured inducible nitric oxide synthase (iNOS) expressions and found pathological changes in the torsed and detorsed testes of the rats. MATERIALS AND METHODS: Adult, male, Sprague-Dawley rats were divided into two groups: I) unilateral left testicular torsion persisting for 1, 4, 8 hours. II) torsion for 4 or 8 hours followed by detorsion. Testes were fixed in scrotal wall with a suture. Testes were fixed in formalin solution and prepared in paraffin blocks and slide mounted. All histologic examinations were done by a single observer. The expression of iNOS gene in the testis was determined by reverse transcriptase-polymerase chain reaction and relative iNOS mRNA levels were assessed with normalization to beta-actin mRNA levels. RESULTS: Histologically, the degeneration and inflammation were found in 4 hours after torsion and the necrosis was found in 8 hours after torsion. In contralateral testis, normal findings were noted in 4 hours and 8 hours after torsion. iNOS gene expression was found in the normal control testis. In the torsed testis, iNOS gene expression significantly increased in 1 hour after torsion, then decreased to the control level. In contralateral testis, iNOS gene expression was also increased in 1 hour to 8 hours after torsion. After detorsion, iNOS gene expression significantly decreased in detorsed testis, but constantly increased in contralateral testis. CONCLUSIONS: In rats, iNOS gene expression and histological changes were observed in torsed and detorsed testes. These results support the hypothesis that NO by iNOS protein may play a role in contralateral testicular damage, such as ischemic-reperfusion injury.

8.Effect of Fibronectin to Macrophage for Destruction of MBT-2 Cell.
Il Young SEO ; Joung Sik RIM ; Hun Taeg CHUNG
Korean Journal of Urology 1996;37(1):1-7
Fibronectin(Fn) is a large, multidomain glycoprotein, which exists in a soluble form in plasma and an insoluble fibrillar form in extracellular matrices. Fn affects many aspects of cellular responses. However, it is not known whether Fn could activate macrophages for the tumor cell killing. We report that Fn induces the tumoricidal activity of macrophages for murine bladder tumor(MBT-2) cell. Tumoricidal activity was determined by 3[H]-thymidine uptake of MBT-2 cell. Fn alone had no effect, whereas recombinant interferon- r(IFN- r) weakly induced the tumoricidal activity of macrophages for MBT-2 cells. However combination of Fn with recombinant IFN-r synergized to activate macrophages to kill MBT-2 cells in a dose dependent manner. At this point nitric oxide(NO) was secreted by activated macrophages, and the secretion of NO and tumoricidal activity of macrophage were inhibited in the presence of NG-monomethyl- L-arginine(NGMMA), a competitive inhibitor of NO synthase(NOS). Fn has various cell binding sites. The Arg-Gly-Asp(RGD) sequence present in the central cell binding domain of Fn is the prototype of these sites. Engineered fibronectin(eFn) is formed by RGD-rich sequence. Combination of eFn, instead of Fn, with recombinant IFN- T resulted in more powerful activation of macrophage in tumor cell killing than Fn. In conclusion, our results demonstrate that Fn acts as a modulator of macrophage activation for tumor cell killing induced by IFN-r via a process involving L-arginine dependent NO production. Especially, RGD sequence of Fn has important role for tumoricidal activity of macrophage. Although the precise mechanism of Fn to promote NO synthesis induced by IFN-r remains to be further elucidated, Fn-mediated macrophage adhesion by specialized cell surface receptors and activation of intracellular signals might be important in the development of macrophage activation.

The most common etiology for female pseudohermaphroditism is congenital adrenal hyperplasia, which accounts for more than 60 percent of children with ambiguous genitalia, and is treated with cortisol replacement and surgical correction of ambiguous genitalia. Flap vaginoplasty, the inverted U-Shaped type has been applied worldwide to the patient with low vaginal entry. The most frequent complication of the operation is contraction of the new vaginal introitus as a result of ischemic and fibrotic changes in the overlapping suture line between the flap and posterior vaginal wall. Maintenance of a good blood supply for the flap and tension free anastomosis should always be kept in mind to avoid this complication. We experienced a vaginoplasty with labioscrotal flap instead of the inverted U-shaped flap and achieved a good result in a 14-year-old girl with low vaginal entry due to congenital adrenal hyperplasia. The labioscrotal flap seems to be more suitable than inverted U-shaped flap for vaginoplasty because the labioscrotal skin is more elastic and more easily elongated than the perineal skin.

The purpose of this study was to examine the effect of smoking on the clinical, radiographic outcome of surgical peridontal therapy. The outcome of periodontal surgery was evaluated in 51 systemically healthy subjects that had received maintenance care. The study subjects consisted of 26 smokers and 25 non-smokers. The average age of smoking patients was 51 years old and non-smoking patients was 48 years old. Changes of probing pocket depth(PPD) and radiographic bone height, and number of missing teeth compared between smokers and non-smokers during maintenance period after surgical therapy. The clinical parameters were less favorable in the smoking group compared with non-smoking group. The number and percentage of missing teeth were greater in smokers(21.6%) than non- smokers(12.4%), especially in molars. The mean presurgery PPD was similar in smokers and non-smokers, molars and premolars, but significantly decreased at least 2 years after surgery. The mean PPD reduction was significantly greater in nonsmokers than smokers. Both in the smoking and non-smoking group, the mean PPD reduction was significantly greater in premolars than molars. The radiographical evaluation was also less favorable in the smoking group than non-smoking group. The radiographic evaluation of bone height in smokers showed bone loss. On the contrary, bone height of nonsmokers showed bone gain during the period of maintenance. But there was no significant difference between molars and premolars. The clinical and radiographic outcomes of the smoking group was less favorable than those of the nonsmoking group. Therefore, smoking seems to influence on the clinical and radiographic outcomes of surgical periodontal therapy.
