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.

Endometriosis in the abdominal wall following Cesarean section is one of the very rare condition among the extrapelvic endometriosis. Although benign, endometriosis possesses the unique ability to invade tissue and to disseminate or metastasize by hematogeneous, lymphatic route, or direct implantation. We reported the case with brief review of the literature.

The purpose of this study was to evaluate the effect of passive or active application of primer and coat times of bond on the shear bond strength when a self-etching primer adhesive (Clearfil SE Bond) was applied to enamel surface. Crowns of sixteen human molars were selected. Buccal and lingual enamels of crowns were partially exposed and slabs of 1.2 mm thick were made. They were divided into one of four equal groups (n = 8). Group 1: passive application of Primer and 1 coat of Bond, Group 2: active application of Primer and 1 coat of Bond, Group 3: passive application of Primer and 2 coats of Bond, Group 4: active application of Primer and 2 coats of Bond. Clearfil AP-X was bonded to enamel suface of each group using Tygon tubes. The bonded specimens were subjected to microshear bond strength (uSBS) testing with a crosshead speed of 1 mm/min. The results of this study were as follows; 1. The uSBS of Group 1 was the lowest among groups and the uSBS of Group 4 was the highest. 2. There was not statistically significant interaction between enamel uSBS by application method of Primer and coat time of Bond (p > 0.05). 3. There was not statistically significant difference between enamel uSBS by passive and active application of Primer (p > 0.05). 4. There was statistically significant difference between enamel uSBS by one- and two-coat of Bond (p < 0.05).

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.

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.

The purpose of this study was to evaluate the microtensile bond strength (microTBS), failure modes and bonding interfaces of self-etching and three self-adhesive resin cements to dentin and indirect composite resin. Cylindrical composite blocks (Tescera, Bisco Inc.) were luted with resin cements (PA: Panavia F 2.0, Kuraray Medical Inc., RE: RelyX Unicem Clicker, 3M ESPE., MA: Maxem, Kerr Co., BI: BisCem, Bisco Inc.) on the prepared occlusal dentin surfaces of 20 extracted molars. After storage in distilled water for 24 h, 1.0 mm x 1.0 mm composite-dentin beams were prepared. microTBS was tested at a cross-head speed of 0.5 mm/min. Data were analyzed with one-way ANOVA and Tukey's HSD test. Dentin sides of all fractured specimens and interfaces of resin cements-dentin or resin cements-composite were examined at FE-SEM (Field Emission-Scanning Electron Microscope). In conclusion, PA and RE showed higher bond strength and closer adaptation than MA and BI when indirect composite blocks were luted to dentin using a self-etching and three self-adhesive resin cements.

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.

It is well recognized that diabetic patients have small pupil. The most likely cause of the abnormally small pupil in diabetics is decreased funcitor of the autonomic nerves. We measured pupil size in 141 control subjects and 53 diabetic patients (29 cases with symptomatic autonomic neuropathy, 24 cases without symptomatic autonomic neuropathy) with portable pupillometry, PUPILSCAN in darkness. Pupils become smaller in healthy and diabetic subjects with advancing age.

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.
