Because there is difficulty in the suture of renal pelvis, extended pyelolithotomy for the renal or pelvic calculi gives often complication such as urine leakage or infection, which result in the fibrosis and stricture of the region. Seven cases of renal stones are treated with new method using 8F Trumpet-shaped Nelaton Catheter. The proximal portion of the Nelaton Catheter inserted into the renal pelvis through the incised opening is made to arrive the lumen of the urinary bladder and the Trumpet-shaped distal portion is made to fix with the suture of the renal pelvis and capsules. After five to seven days, the catheter is removed by cystoscopic manipulation. It seems that the method is easy and feasible to decrease the complication of the extended pyelolithotomy for renal calculi.

To determine the frequencies of the genotypes of NAT2 gene in healthy Korean populations and to identify the high-risk genotypes of NAT2 gene in colorectal cancer patients, 115 healthy controls and 109 cancer patients were analyzed using polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). The distribution of NAT2 polymorphism in healthy Korean was found to be 7.8% of S/S genotype, 48.7% of S/F genotype, and 43.5% of F/F genotype. And the frequency of phenotypes was 8% of slow acetylator and 92% of rapid acetylator. S/S genotype of colorectal cancer patients was slightly more frequent than that of healthy controls(11.9% vs 7.8%). The relative risk of S/S genotype to colorectal cancer was estimated to be 1.41, taking the risk of F/F genotype as a baseline(1.00). These results suggest that the distribution of frequencies of NAT2 genotypes is very unique in Korean characterized by extremely low frequency of slow acetylator geno type(S/S) in comparison to the other ethnic groups. And the slow acetylator genotype(S/S) in Korean was found to be more susceptible to colon cancer. Therefore, S/S genotype may have a certain role an colonic carcinogenesis in Korean.

Adult Wilms' tumor is rare unlike its pediatric counterpart. Because there is no specific radiologic findings of adult Wilms' tumor it is very difficult to diagnose the adult Wilms' tumor preoperatively and the final diagnosis is usually established with surgery. We report a case of Wilms' tumor in 26 years old postpartum woman with review of the literature.

Random biopsy of normal-looking mucosa of the bladder at the time of T.U.R.B. in the patients with bladder cancer have been used as a routine assessment of the tumor behavior. To investigate mucosal abnormalities of normal-looking mucosa in bladder cancer. we performed random mucosal biopsies during transurethral resection of the bladder cancer. The following results were obtained. 1. In Group 1 (Solitary, Stalk, Papillary ca). no CIS lesion was found in biopsy specimens. 2. In Group 2 (Solitary. Sessile. Papillary ca) and Group 3 (Solitary. Sessile. Non-papillary ca). some positive results were obtained. On the consideration of above results and the potentiality of implantation. we can raise an issue that the bladder cancer patients with a solitary, papillary shape do not necessarily undergo the mucosal biopsy during T.U.R.B. Instead, close follow up for the patients will be recommended.

A case of ovarian dermoid cyst invading the posterior bladder wall with pilimiction and recurrent bladder stone was presented. Fifty-four years old female patient had a symptoms of frequency, dysuria, hematuria and pilimiction intermittently She had received cystolithotomies and litholapaxy due to recurrent bladder stones for 3 times in other hospitals Cystoscopic examination revealed elevated flat mass on the base of bladder and hairs outgrowing a from the surface of mass. Also two-large bladder stones were seen at cystoscopy. So, recurrent bladder stones caused by the hairs growing from invading dermoid cyst was diagnosed. Removal of bladder stone, partial cystectomy and left oophorectomy were performed.

A patient is described who was presented with a little finger tip sized palpable nodular mass on left calf muscle for 2 years of duration. The pathologic result of the biopsy specimen for nodular mass showed a clear cell carcinoma. The full metastatic work up demonstrated tumor in the right kidney, with no other detectable primary focus. Result of the radical nephrectomy exhibited renal cell carcinoma confined within renal parenchyme. The patient was treated with IFN-alpha-2b as adjuvant therapy and now is on close observation without the evidence of tumor recurrence.

Small cell carcinoma of the urinary bladder is very uncommon tumor and it's clinical entity is characterized by an aggressive clinical course with early metastases. We report a case of the primary small cell carcinoma of urinary bladder in a 66 year old man who was managed by partial cystectomy and combined chemotherapy using cisplatin and etoposide.

Benign prostatic hyperplasia is one of the most common afflictions in an aged man, but the surgery has been the only therapeutic option in the treatment of benign prostatic hyperplasia. Recently, other alternative therapeutic modalities such as pharmacological, hormonal, less invasive treatment(laser, stents, thermotherapy, etc.) were developed. The prostatic laserthermia is one of the new therapeutic tool being evaluated for the treatment of BPH. The aim of this study is that the prostatic laserthermia will be an alternative therapeutic modality for BPH as transurethral resection of prostate(TURP). A total of 92 patients(ages 49 to 90 years) who were diagnosed as BPH were included in the study, underwent uroflowmetry, transrectal ultrasound and AUA symptom scoring. 34 of 92 patients were treated with TURP. And 58 of the 92 patients were treated with prostatic laserthermia. After the treatments, each patients were followed by uroflowmetry and AUA symptom score at post operative 1, 3 and 6 months. In TURP group, the preoperative peak flow rate was changed from 8.33+/-4.5ml/sec, to 14.65+/-4.74 ml/sec, 14.67+/-4.08 ml/sec and 14.60+/-4.63 ml/sec, at postoperative lst, 3rd and 6th month respectively. The amount of average residual urine was decreased from 158.l+/-121.6 ml, to 41.9+/-22.3 ml, 43.3+/-27.1 ml and 58.2+/-27.5 ml, at 1st, 3rd and 6 month respectively. Also the AUA symptom score was decreased from 22.5+/-7.0, to 9+/-4.7, 9.3+/-4.3 and 9.5+/-5.2, at postoperative 1st, 3rd and 6th month. In prostatic laserthermia group, the preoperative average peak flow was 9.33+/-6.30 ml/sec, changed to 11.46+/-5.20 ml/sec, 11.67+/-5.40 ml/sec and 11.72+/-5.27 ml/sec at postoperative lst. 3rd and 6th month. The preoperative average mean flow was 4.75+/-2.87 ml/sec, increased to 5.47+/-2.69 ml/sec, 5.l8+/-2.69 ml/sec and 5.28+/-3.06 ml/ sec at 1st, 3rd and 6th month. The preoperative average residual urine was 130.9+/-154.7 ml/sec, decreased to 59.9+/-66.6 ml/sec, 50.6+/-57.0 ml/sec and 31.3+/-45.7 ml/sec at postoperative lst, 3rd and 6th month. The preoperative average AUA symptom score was 27.0+/-5.9, decreased 19.1+/-8.1, 18.4+/-8.7 and 17.5+/-9.1 at 1st, 3rd and 6th month. When comparing the parameters between two treatment groups, improvement of peak flow rate was greater in TURP than in Prostatic laserthermia group(p<0.01). Decrease of AUA symptom score and amount of residual urine also were greater in TURP than in prostatic laserthermia group. As the result TURP is more effective than prostatic laserthermia in peak flow rate at 1st month and AUA symptom score at lst, 3rd and 6th month t < 0.05). But laserthermia also appears to be as effective as TURP in the decrease of postvoid residuals. It could be suggested that prostatic laserthermia is an alternative therapeutic modality of BPH, especially old man who has some risk factors for operation. Key Word : transurethral resection, laserthermia.
