    ABSTRACT: Iliac vein-ureteral fistula is a rare cause of hematuria. The diagnosis of an iliac vein-ureteral fistula can be elusive even with the use of multiple methods. With regards to the treatment, there appears to be a shift in management from primarily open surgical to primarily angiographic management. We present a unique case of an external iliac vein - transplant ureteral fistula. A 48 year-old female complained of recurrent gross hematuria. She underwent transplant nephrectomy and radical left nephrectomy because of rejection of transplanted kidney and cystic renal cell carcinoma when the hematuria arose for the first time. Ten months later, the hematuria recurred again, and cystoscopy showed bleeding from the right transplant ureteral orifice. Open exploration confirmed the diagnosis of external iliac vein - transplant ureteral fistula. Diagnostic difficulties and treatment dilemma of such a rare cause of hematuria are also discussed.

    ABSTRACT: The aim of the study was to review the clinical features and treatments of 10 (9 males and 1 female; age range, 61-73 years; median age, 67 years) upper urinary tract inverted papilloma (IP) cases between 1995 and 2010. The clinical syndromes, diagnostic procedures, treatments and results of the follow-up were evaluated. The results showed that the site of tumor development was the ureter in 6 cases and the renal pelvis in 4 cases. It was also identified that 7 tumors developed on the left side and 3 developed on the right side of the ureter and renal pelvis, respectively. A nephroureterectomy was performed in the first 6 cases, while a partial ureterectomy was performed in 3 cases and a local resection was performed endoscopically in 1 case. All but 2 tumors were solitary, ranging from 5 to 30 mm in diameter. Occurrence in association with transitional cell carcinoma was identified in one case. All 10 patients were subject to follow-up (range, 19-120 months; median, 59 months), during which no recurrence was found. Local excision is considered as adequate treatment when upper urinary tract IP is diagnosed according to strictly defined criteria.

    ABSTRACT: To explore whether the anti-tumor action of 17beta-estradiol is enhanced by re-expression of the homeodomain transcription factor Nkx3.1 in PC3 human prostate cancer cells. PC3 cells were stably transfected with pcDNA3.1-Nkx3.1-His vector, which carries a full-length cDNA of human Nkx3.1. The PC3 cells stably transfected with vector pcDNA3.1 were set as a control. The expression of Nkx3.1 protein in the cells was confirmed by Western blot analysis. The effect of Nkx3.1 on cell proliferation of PC3 cells was examined with MTT assay. The antiproliferative and apoptotic effects of 17beta-estradiol alone or in combination with Nkx3.1 were estimated on PC3 cells by using MTT growth tests and flow cytometric analyses. The expression of apoptosis-related proteins was analyzed using Western blotting. The plasmid carrying Nkx3.1 gene induced high expression of Nkx3.1 protein in PC3 cells. The re-expression of exogenous Nkx3.1 did not cause a significant reduction in cellular proliferation, whereas the expression of Nkx3.1 enhanced the 17beta-estradiol anti-proliferative effect in PC3 cells. Nkx3.1 expression promoted 17beta-estradiol-induced apoptosis of PC3 cells, as shown by analysis of Bcl-2, Bax, Caspase-3 and poly (ADP-ribose) polymerase expression. The present study demonstrates that re-expression of Nkx3.1 enhances 17beta-estradiol anti-tumor action in PC3 human prostate cancer cells. The in vitro study suggests that re-expression of Nkx3.1 is worthy of further consideration as an adjuvant treatment of androgen independent prostate cancer with estrogen anti-tumor therapies.

    ABSTRACT: To evaluate the effect of sexual-nerve-sparing radical cystectomy. Thirty-two male patients were treated with sexual-nerve-sparing radical cystectomy in our hospital in the past 5 years. The age of the patients ranged from 38 to 72 years, with the course of the disease ranging from 2 days to 20 years. All of them were potent preoperatively. Radical cystectomy was performed antegradely and retrogradely with the neurovascular bundle spared. The patients were followed up for 6 to 54 months, 3 achieved sexual activity of Grade I, 6 Grade II and 23 Grade III after the operation. The recovery time of erectile function ranged from 2 to 14 months, averaging at 4. 5 months. Whenever condition suits, sexual-nerve-sparing radical cystectomy is to be strongly recommended.

    ABSTRACT: To investigate the clinical features, pathology, diagnosis and treatment of inverted urothelial papilloma. A total of 151 cases of urothelial inverted papilloma were analysed retrospectively. Of the cases, 134 were male and 17 were female, with a mean age of 54 years old. Most patients complained of painless gross hematuria. The diagnosis could be established mainly by ultrasonic, intravenous urography, retrograde pyelography, cystoscope and pathology. Among them, 7 cases who had the papilloma at upper urinary tract underwent nephroureterectomy except one. One hundred and forty-four cases had the papilloma at low urinary tract, with 124 treated by transurethral bladder tumor resection (TURBT), among which 11 cases accompanying benign prostatic hyperplasia were treated by transurethral prostatic resection, 3 by transurethral resection of prostatic urethral tumor, 15 by partial cystectomy, 2 by total cystectomy. One hundred and eighteen cases were followed up 1 year to 12.5 years (mean 6.3 years). Intravesical recurrence was found in 5 cases. Of them 2 cases developed malignance in 8 and 30 months postoperatively, and 1 case underwent total cystectomy. Inverted urothelial papilloma is a benign tumor, which appears male predominant. Most of the lesions are found in the bladder. TURBT is the preferred treatment choice for inverted papilloma of the bladder. Although this disease has a good prognosis, regular follow-up observations are necessary.
