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).

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.

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.

Granulocytic sarcoma is an uncommon extramedullary tumor composed of granulocytic precursor cells such as myeloblasts or monoblasts. These tumor were originally called chloroman because of the green color imparted by the heavy concentration of the myeloperoxidase present in myelogenous leukemic cells. The tumor usually develops during the course of myelogenous leukemia or myeloproliferative disorders and may represent the initial manifestation of leukemia. Rarely, granulocytic sarcoma is recognized as an isolated tumor without any evidence of leukemia. We report a case of a 21-year-old man who was diagnosed as granulocytic sarcoma of right kidney after complete remission of acute myelocytic leukemia.

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.

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.

Incomplete bladder emptying even after prostatectomy were not uncommonly anticipated in patients with benign prostate hypertrophy (BPH) who had episodes of acute urinary retention. This may be related h impaired contractility of detrusor muscle secondary to decreased blood flow to the bladder and over-stretching of detrusor muscle caused by overdistension of bladder. We measured detrusor contractility in 41 patients with BPH who had episodes of urine retention (Group A) and 77 patients with BPH without urine retention. Also, follow up uroflowmetry were taken for 25 patients of group A and 40 patients of group B in 30-50 days after prostatectomy. Results were as follows; I. On filling cystometry. first sense of fill, urge sense to void, maximum cystometric capacity and compliance were not significantly different between 2 groups and detrusor instability were 23 cases (56%) in group A, 38 cases (49%) in group B. 2. On pressure-flow study, maximum detrusor voiding pressure was 32.5+/-4.13 cmH2O in group A and 50.27+/-2.4 cmH2O in group B (P<0.01). Peak flow rate (Qmax) and voided volume were 4.1 to 0.7 ml/sec, 76.1+/-12.7 ml in group A and 8.6+/-0.65 ml/sec, 176.1+/-16.7 ml in group B respectively (P<0.01, P<0.01). Residual urine was 256.5 1:24.3 ml in group A and 111.6 t 14.7 ml in group B (P<0.01). 3. On postoperative follow up uroflowmetry, voided volume and Qmax were increased compared to preoperative value in group A but still lower than those in group B (P<0.05, P<0.05). 4. The number of patients who didn't show any improvement of voiding symptoms after surgery were 17 on group A and 11 on group B. Impaired detrusor contractility was present in 25 of 41 cases (61%) of group A and 10 of 71 cases (13%) of group B on urodynamic diagnosis. Conclusively, in patients with BPH who had episodes of urine retention, preoperative pressure-flow study to recognize impaired detrusor contractility would be helpful in anticipating incomplete bladder emptying after prostate surgery and considering other forms of ancillary therapy.
