To investigate the learning curve of robotic-assisted laparoscopic radical prostatectomy (RALP) and analyze whether a surgeon's prior surgical experience has effects on the surgery.From April 2012 to August 2015, 3 surgeons performed RALP on 355 consecutive patients with prostate cancer. Among these cases, 184 were by surgeon A with prior open experiences, 92 by surgeon B with both open and laparoscopic...
To compare the perioperative outcomes and cosmetic results for transumbilical (TU), transperitoneal subcostal (TS), and retroperitoneal subcostal (RS) laparoendoscopic single-site surgery (LESS) adrenalectomy (AD).An observational study was conducted of patients who were had undergone LESS-AD using a TU (n = 9), TS (n = 17), or RS (n = 16) approach. The perioperative outcomes and comprehensive cosmetic...
To investigate the expression pattern of Ras-related protein 1 (Rap1) during testicular development and to clarify whether its expression is developmentally regulated and whether this expression is involved in the process of germ cell apoptosis.The expression pattern of Rap1 in the adult rat testicle was compared with that in the developing rat testicle using immunoblotting and immunohistochemical...
To investigate whether the normal expression of metastasis-associated protein 1 (MTA1) in Sertoli cells (SCs) is associated with adjacent germ cells (GCs) and to provide the functional relevance of MTA1 in this somatic cell.The expression pattern of MTA1 in the SCs of impaired human spermatogenesis was determined using immunohistochemistry. The effect of the depletion of GCs on the expression of MTA1...
To evaluate the 1-year efficacy and safety of single-port transvesical enucleation of the prostate (STEP) for voluminous benign prostatic hyperplasia (BPH). Nine patients with moderate- to large-volume (83.8 ± 19.9 mL) BPH (mean age 71.9 ± 6.39 years, body mass index [BMI] 21.5 ± 3.25 kg/m 2 ) were preoperatively evaluated by abdominal and transrectal ultrasonography, uroflowmetry, International...
A 21-year-old female presented with a retroperitoneal mass in the right side and a centrally located renal mass in the left kidney with an aberrant vascular anatomy of a double inferior vena cava. The 2 tumors were radically excised by a transperitoneal laparoscopic approach in one session. Histopathologic examination revealed the right retroperitoneal lesion to be a schwannoma and the renal mass...
To compare the intraoperative and early postoperative outcomes of robotic partial nephrectomy (RPN) with those of laparoscopic partial nephrectomy (LPN) outcomes in patients with bilateral synchronous renal tumors. RPN is emerging as an attractive minimally invasive nephron-sparing approach for renal tumors.Our ongoing institutional review board-approved, prospectively maintained, kidney cancer database...
To evaluate the safety and feasibility of robotic partial nephrectomy for patients with complex renal masses.We reviewed the data for 164 consecutive patients who had undergone transperitoneal robotic partial nephrectomy at a tertiary care center from February 2007 to June 2010. Of the 112 patients who had available imaging studies to review, 67 were identified and classified as having a moderately...
To evaluate a combined analysis approach that involves cytologic evaluation and fluorescence in situ hybridization analysis (FISH) for detecting urothelial carcinoma (UC) in the upper tract (UT).By refining the UroVysion positive criteria, an analyzing modality (Cyto-FISH) combined urine cytology and FISH analysis (UroVysion probe set) was introduced and urine specimens from 71 patients with UT-UC...
To describe novel robotic laparoendoscopic single-site surgery (R-LESS) instruments, and present the initial laboratory experience in urology.The VeSPA surgical instruments (Intuitive Surgical, Sunnyvale, CA) were designed to be used with the DaVinci Si surgical system. A multichannel port and curved cannulae were inserted through a single 3.5-cm umbilical incision. The port allowed 1 scope, 2 robotic...
