Abstract PDF PubReader ePub: Objectives
We designed the study to compare the oncologic and renal function outcomes of off-clamp, laparoscopic partial nephrectomy (OCLPN) and conventional laparoscopic partial nephrectomy (HCLPN) for renal tumors.
Methods
Between March 2008 and July 2015, 114 patients who underwent laparoscopic partial nephrectomy (LPN) of a renal neoplasm were studied. We performed LPN without hilar clamp on 40 patients (OCLPN, Group 1), and conventional LPN with hilar control and renorrhaphy on another 40 patients (HCLPN, Group 2). We retrospectively reviewed the medical records of each patient's age, sex, R.E.N.A.L. nephrometry score (RNS), operation time, complications, hospitalization period, tumor size, positive resection margin, histologic classification of tumor, pathologic stage, Fuhrman grade, estimated blood loss (EBL), warm ischemic time (WIT), and estimated glomerular filtration rate (eGFR) before and one year after surgery.
Results
There were no significant differences in age, sex, preoperative eGFR, EBL, surgical (anesthesia) time, and tumor size between the two groups. The mean eGFR was not significantly different between the OCLPN and HCLPN groups 1 month (95 and 86.2 mL/min/1.73 m², respectively; P = 0.106), 6 months (92.9 and 83.6 mL/min/1.73 m², respectively; P = 0.151) and 12 months (93.8 and 84.7 mL/min/1.73 m², respectively; P = 0.077) postoperatively. The change in eGFR after one year was 3.9% in the OCLPN group and −7.9% in the HCLPN group.
Conclusions
OCLPN was superior to HCLPN in preserving renal function one year after surgery, and there was no statistically significant difference in tumor treatment results.

Abstract PDF PubReader ePub: Abstract
Prostate cancer is increasing in frequency in Korea. Among them, ductal adenocarcinoma (DCP) has a more aggressive and poor prognosis than acinar adenocarcinoma (ACP), despite its low incidence. Patients usually present with symptoms of lower urinary tract symptoms and hematuria due to increasing tumor mass within the lumen of the prostatic urethra, making diagnosis of DCP by the transrectal prostate biopsy difficult. DCP is often metastasized at the time of diagnosis. DCP is transferable to most other organs but the metastasis to the anterior urethra is rare. There is no doubt that localized DCP requires radical prostatectomy (RP) but the guidelines for adjuvant therapy after RP have not yet been established. Methods of the treatment are confounded by individual differences, and arriving at a consensus is challenging due to insufficient data. We report a case of DCP and urethral metastasis after RP, thus aiding in the determination of treatment guidelines.
