Purpose: We compared renal function outcomes in patients undergoing open or laparoscopic radical nephrectomy. Materials and Methods: Seventy-one patients undergoing open or laparoscopic radical nephrectomy for kidney disease with a normal contralateral kidney were identified between January 2004 and December 2007. Renal function was calculated by using the Cockcroft-Gault formula. Serial renal functions were checked from the day before surgery to 1 year after surgery. Exclusion criteria were preexisting renal insufficiency, urinary stone disease, and pancreatic and liver disorders. Results: Forty-one and 30 patients were treated with open radical nephrectomy or laparoscopic radical nephrectomy, respectively. The operative time and urine output of patients who underwent open and laparoscopic radical nephrectomy were 211.7±5.8 and 330.8±15.6 and 196.4±19.6 and 130.7±12.1, respectively (p=0.001, p=0.013). The glomerular filtration rates of patients who underwent open or laparoscopic radical nephrectomy were insignificant from baseline to postoperative day 360 (p>0.05). Conclusions: No significant differences in renal function were detected in the groups of patients who underwent open or laparoscopic radical nephrectomy from baseline to long-term follow-up.

Stress urinary incontinence is a common problem which can be corrected surgically. Burch colposuspension is one of successful operation performed for stress urinary incontinence. We report a patient who presented urgency, tenesmus, frequency, dysuria after Burch colposuspension. Any patients with unexplained lower urinary tract symptoms following Burch colposuspension must be evaluated radiologically and urologically to find iatrogenic bladder stone.
Experimental Animal Models of Neurogenic Bladder Dysfunction

Neurogenic bladder is related to various types of neurogenic disease and injury, including cerebrovascular accident, brain tumor, spinal cord injury, and Parkinson’s disease. The results of urodynamic study show different types of detrusor and sphincter function. According to these urodynamic results, the physician decides on a treatment plan, such as anticholinergics or alpha- blockers. In the development of a new medication, it is necessary to test the medication’s efficacy and toxicity by using a laboratory animal. The proper laboratory animal should have several characteristics. These are biological similarity to humans, a short generation period, and an environment that is easy to control. We describe the development of laboratory animals for the study of neurogenic bladder by decerebration, stroke, and spinal cord injury.

Benign prostate hyperplasia (BPH) is the most common cause of lower urinary tract symptoms (LUTS) in men older than the middle age, and is a pathologic process that contributes to lower urinary tract symptoms in aging men. Despite the significantly different proportion of men with moderate to severe symptoms, a clear trend toward an increase in symptom scores with advancing age is noticeable. Complications of LUTS and BPH, such as urinary tract infections, bladder decompensation, bladder stones, hematuria, urinary incontinence, upper urinary tract deterioration with renal insufficiency, and others are in general rare in properly supervised patients. Medical therapies investigated for BPH include α- adrenergic blockers, 5α- reductase inhibitors, combination, aromatase inhibitors, and numerous plant extracts. Medical therapy is now the usual first- line management of uncomplicated BPH with either an α- adrenergic blocker or (if the prostate is large) a 5α- reductase inhibitor. Combination therapy with both an α- adrenergic blocker and a 5α- reductase inhibitor has been demonstrated to be the most effective means of preventing disease progression.

Cytokines such as interleukin 10 (IL10) may play an important role in the process of inflammation. The aim of this study was to analyze the association between IL10, IL10RA and IL10RB single nucleotide polymorphisms (SNPs), and benign prostate hyperplasia (BPH)in Korean population. All patients with BPH were divided into two groups according to international porostate symptom score (IPSS), prostate specific antigen (PSA) level, Q_max,and prostate volume. We selected two IL10 SNPs (rs1518111 and rs1554286), three IL10RA SNPs (rs2256111, rs4252243, and rs2228054), and two IL10RB SNPs (rs999788 and rs2834167). Genotypes of seven SNPs were determined through direct sequencing. The G/G genotype of IL10RB polymorphism (rs2834167) was associated with a high PSA level compared with the A/G + A/A genotypes (P = 0.009). Of IL10 SNP, the A/A genotype of rs1518111 and T/T genotype of rs1554286 were associated with small prostate volume,respectively (P = 0.011, P = 0.014). Moreover, the T/T genotype of IL10RB polymorphism (rs999788) was associated with high prostatic volume compared with the T/C + C/C genotypes (P = 0.033). The linkage disequilibrium (LD) blocks were formed in IL10 and IL10RA. However, haplotypes in the LD block were not associated with BPH. It is concluded that there is a strong association between the IL10 and IL10RB SNPs, and BPH in Korean population.
