I have managed fifty cases of lower ureteral stone who were admitted to the Department of Urology, Yungdong-Hospital during from May 1991 to July 1992. 1. Between May 1991 and April l992, 40 cases of lower ureteral stone were managed. Among them, 11 cases were extracted with the Dormia stone basket, 6 cases were performed ureteral meatotomy, 11 cases were delivered spontaneously, 3 cases were removed with ureterolithotomy and 9 cases transferred to other hospital. Over all success rate of stone removal were 62.5% (25 cases). 2. Between May 1992 and July 1992, 10 cases of ureteroscopic removal of lower ureteral stone were performed. All cases were removed successfully. Complications occurred in 7 cases, but managed conservatively in all cases. I agree that ureteroscopic removal of stone is also the treatment of choice for lower ureteraI stone in non-training hospital.

Aggressive angiomyxoma is a rare, locally aggressive tumor and occurs exclusively in the pelvic and perineal regions of women. But this tumor can occur in men, and the ratio of man to woman is about 1:6. We report a case of aggressive angiomyxoma of the scrotum in a 75-year-old man. The resected mass measured 23 21 10 cm and weighed 1,150 g, and was covered with thick but intact scrotal skin. The cut surface of the mass showed pale yellow to grayish white loose and edematous fibrous tissue with focal cystic degeneration. Microscopically, the mass was composed of loosely arranged bland-looking spindle or stellate cells and variable sized blood vessels with thickened and hyalinized wall. The spindle cells were strong positive for vimentin, focal, weak positive for desmin and smooth muscle actin but negative for S-100 protein. The spindle cells were also positive for estrogen and progesterone receptors.

The presence of gas in the substance of the kidney, perinephric area or collecting system may result from infection, penetrating trauma, fistulous connection with the gastrointestinal tract or skin and instrumentation or surgical manipulation. I experienced a case of perirenal emphysema which occurred in rupture of the duodenum due to blunt abdominal trauma.

We studied the activity of adenosine deaminase in the urine of 38 patients who were divided into four groups :Urinary tract tuberculosis without ureteral obstruction(Group I ), Urinary tract tuberculosis with ureteral obstruction (Group II ), Urinary tract infection ( Group III ) and control subjects (Group IV). In patients with urinary tract tuberculosis with ureteral obstruction the adenosine deaminase activity in aspirated renal urine was significantly higher than for the rest of the groups (p<0.001). Adenosine deaminase activity in renal aspirated urine has proved to be a simple and reliable diagnostic method for urinary tract tuberculosis with ureteral obstruction.

A prospective study was carried out on the efficacy of a circular grip which we devised to facilitate a non-sterile intermittent catheterization. The series included 16 females, the mean follow-up time being 7 months. Most patients were suffering from neurogenic bladder disorders and bladder retention after operation. All of them used the circular grip during intermittent catheterization and continued to undergo intermittent catheterization. The technique of the use of the circular grip during intermittent catheterization was usually learnt easily and provided reassurance to the patient and family about intermittent catheterization.

PURPOSE: We compared the safety and efficacy of ureteroscopy with intravenous propofol anesthesia with those with spinal anesthesia for the treatment of lower ureteral calculi. MATERIALS AND METHODS: Ureteroscopy with intravenous propofol anesthesia was performed in 38 patients with ureteral caluli, and spinal anesthesia was performed in 41. Ureteroscopy was performed with a 9.5Fr rigid ureteroscope. RESULTS: The overall success rate of stone removal was 99% (100% in IV propofol anesthesia cases and 98% in spinal anesthesia cases). Hospital stay times were significantly shorter for patients given propofol: 1.5 vs 3 days, respectively(p<0.05). CONCLUSIONS: Stone removal under intravenous propofol anesthesia does not increase the risk of complication or compromise the results of treatment and hospital stay times.

PURPOSE: We studied the crystallographic component of the prostatic calculi according to the location on the transrectal prostatic ultrasonography to know the mechanism of the formation of the calculus. MATERIALS AND METHODS: From August, 1995 until May, 1997, 33 prostatic calculi from 24 patients(mean age 59 years, mean size 3.1mm) operated on for prostatism were analyzed by polarization microscopy(ZeissR), X-ray diffraction(PW-1720R, Philips) and infrared spectrophotometer(FTIR-205R, Nicolet). Location of calculi was divided two groups under guide of transrectal prostatic ultrasonography; periurethral and periadenoma type. The periurethral type showed hyperechoic density around the prostatic urethra and the periadenoma type showed hyperechoic density between adenoma and false prostatic capsule(peripheral zone). RESULTS: 22 calculi were the periurethral type and 11 were periadenoma type. Thirty stones from 20 periurethral type and 10 periadenoma type consisted two or three of the following calcium phospate, calcium oxalate and tricalcium phospate. These are mixed by the endogenous origin formed from the prostatic fluid and the exogenous origin formed at least in part from urine. Three stones (2 calcium oxalate, 1 uric acid) contained only one compound which participitate from urine. All of 11 calculi of the pericapsular type had an oxalate component. CONCLUSIONS: The calculi around the periadenoma region may be formed from not only endogenous component(calcium apatite stone) but also exogenous component(calcium oxalate) or intraductal precipitation of oxalate component which has never found in the prostatic fluid. These results may suggest the necessity of reevaluation about oxalate component within the prostatic fluid.

Thromboangiitis obliterans is a specific, recurrent segmental, inflammatory, obliterative vascular disease involving principally medium sized arteries and veins of the extremies. Thromboangiitis obliterans of the spermatic cord is an exceedingly rare condition and reported less than 10 cases in the literature. We submit a case suffering from thromboangiitis obliterans of the spermatic cord.

Transrectal ultrasonography is one of the most available techniques to evaluate prostatic disease and is far more accurate than conventional ultrasonography. A retrospective review of ultrasonographic characteristics of the prostate was made in an attempt to define the ability of the technique to distinguish benign from malignant prostatic disease. Analysis included evaluation of the capsule, abnormal foci (echo brightness, echo thickness) and calcification. Transrectal ultrasonography was performed in 79 cases and the results were compared with the pathologic results of prostatic tissue obtained by transperineal ultrasound guided or transurethral prostatic resection. Acoustic characterization of abnormal small foci within the gland has a moderate degree of overlap, but may suggest the differentiation of benign and malignant disease.

From 1980 to 1986, 32 patients had suffered from bladder rupture. Among these patients 14 were due to direct blow, 10 due to traffic accident, 2 due to slip down, 1 due to falling down, and unknown origin was seen in 4 cases. We evaluated these patients with age, sex, presence of pelvic bone fracture, urologic sign and symptom, size and site of ruptured bladder due to blunt trauma.
