PURPOSE: Infection of the external urogenital system with human papillomavirus (HPV) has been implicated in the development of genital cancer. We evaluated the prevalence of HPV types 6/11, 16 and 18 deoxyribonucleic acid (DNA) by polymerase chain reaction (PCR) and the localization of HPV DNA by in situ hybridization. MATERIAL AND METHOD: A total of 22 formalin-fixed, paraffin-embedded specimens of invasive squamous cell carcinoma of the penis were analyzed. We used the PCR technique to evaluate type specific DNA sequences of unique E6 to E7 transforming regions of HPV. Also, we investigated the localization of HPV DNA by in situ hybridization in PCR positive cases. RESULTS: Overall, by PCR technique the detection rate for HPV DNA were 50% (11 of 22 cases). HPV DNA type 16 was detected in all positive specimen and type 6/11 in 5 cases, whereas type 18 could not be detected. All of HPV DNA type 6/11 positive specimens were also HPV DNA type 16 positive. Using in situ hybridization HPV DNA type 16 was detected in 2 (18.2%) from 11 specimens in which HPV DNA had already been detected by PCR, and HPV DNA type 16 was localized in the nuclei of scattered carcinoma cells. But, HPV DNA type 6/11 were not detected by in situ hybridization. CONCLUSIONS: These findings suggest that HPV DNA type 16 is the type most commonly associated with penile carcinoma. But the result of high detection rate for HPV DNA type 6/11 seems to require further investigations.

PURPOSE: We evaluated whether increased split renal function ratio (%) on the renal scan with Tc-99m diethylenetriamine pinta-acetic acid (DTPA) represent elevated renal function in the obstructed kidney. MATERIALS AND METHODS: From 1994 to 1995, we evaluated 36 patients with unilateral hydronephrosis due to ureteropelvic junction (UPJ) obstruction and split renal function ratios of the affected kidneys were calculated using Tc-99m DTPA renal scan. RESULTS: Of the 36 patients, 7 patients showed that split renal function ratios of the affected kidneys were all over 52%. To assess the significance of the split renal function ratio on the Tc-99m DTPA renal scan, we performed Tc-99m mercaptoacetyltriglycine (MAG3) renal scan with the time interval of 3 days and calculated the split renal function ratios of the affected kidneys on the MAG3 renal scan in all 7 patients. The split renal function ratios of the affected kidneys on the MAG3 renal scan were also higher than those of the normal kidney. And the split renal function ratios of the affected kidneys on the MAG3 renal scan were well correlated with those of DTPA renal scan (r=0.83). CONCLUSIONS: Our results suggest that the increased split renal function ratio in affected kidney due to UPJ obstruction is not an artifact of the DTPA renogram.

Emphysematous pyelonephritis is an uncommon serious suppurative infection characterized by the production of intrarenal and perirenal gas and generally occurs in patient with diabetes mellitus or urinary tract obstruction. We report a case of emphysematous pyelonephritis treated successfully with percutaneous drainage in 61-year-old woman with diabetes mellitus, mitral insufficiency and pleural effusion.

We report two cases of bilateral renal angiomyolipoma with tuberous sclerosis who had skin lesions like butterfly shaped adenoma sebaceum on face, shagreen patch on back, leaf-shaped hypopigmented spot on both extremities, mental retardation, and seizure, which they are treated unilateral simple nephrectomy and selective arterial embolization, each other.
