Purpose: We investigated the safety and efficacy of transurethral resection of the prostate(TURP) in benign prostatic hyperplasia(BPH) more than 60cc by single surgeon for the relief of infravesical obstruction. Materials and Methods: We evaluated 211 patients treated with TURP in BPH with large prostate by single surgeon. Each group was divided by prostate volume(group 1; 60-69.9, group 2; 70-79.9, group 3; 80-89.9, group 4; 90-99.9, group 5; >100cc of prostate volume). Various parameters such as International Prostate Symptom Score(IPSS), maximal flow rate(Qmax.), postvoid residual volume(PVR), prostate volume, adenoma volume, resection time, resection prostate volume, irrigation fluid volume and complications were evaluated and compared. Results: Age of each group was not significantly different. Prostate volume, adenoma volume, resection time, Resection volume, irrigation volume of each groups were different significantly. But, resection volume/resection time and irrigation volume/resection time were not different significantly. Mean resection volume/resection time was 1.34g/min, and mean irrigation volume/resection time was 315.8ml/min. And intraoperative and postoperative complications of each group were not different. Mean postoperative change of Hb was 2.0±1.1g/dl. Postoperative parameters(IPSS, Qmax, PVR) were improved significantly. Only 2 patients needed transfusion in group 5. No urinary incontinence and TUR syndrome in each group was observed. Conclusions: TURP by experienced surgeon is a safe and effective treatment in BPH patients with large prostates for relief of infravesical obstruction.

Purpose: To investigate the feasibility of a polycaprolactone (PCL) scaffold fabricated by three-dimensional (3D) printing for tissue engineering applications for tunica albuginea.Materials and Methods: PCL scaffolds were fabricated by use of a 3D printing system. Two scaffolds were fabricated that differed in the architecture of the lay-down pattern: a 90°PCL scaffold and a 45°PCL scaffold. Mechanical properties were measured to compare tensile strength between the two scaffold types. The scaffolds were characterized by scanning electron microscope (SEM) images. The scaffolds were seeded with fibroblast cells, and the ability of these scaffolds to support the cells was evaluated by immunofluorescence staining.Results: The PCL scaffolds had well-structured shapes, regular arrays, and good interconnection in SEM images. The horizontal and vertical Young’s modulus coefficients were 13 and 12 MPa for the 90°PCL scaffold and 19 and 21 MPa for the 45°PCL scaffold, respectively. Microscopy images revealed that human fibroblast cells covered the entire scaffold surface. Immuno-fluorescence staining of ER-TR7 confirmed that the fibroblast cells remained viable and proliferated throughout the time course of the culture.Conclusions: This preliminary study provides experimental evidence for the feasibility of 3D printing of PCL scaffolds for tissue engineering applications of tunica albuginea.

Purpose: Recent studies have highlighted an increasing trend of infectious complications due to fluoroquinolone-resistant organisms among men undergoing transrectal prostate biopsy. This study evaluated the current incidence of infective complications after trans-rectal prostate biopsy for identification of risk factors in Korean men who received fluoroquinolone prophylaxis.Materials and Methods: A prospective, multicenter study was conducted in Korea from January to December 2015. Prostate biopsies performed with fluoroqui-nolone prophylaxis during 3 months in each center were included. A pre-biopsy questionnaire was used for identification of patient characteristics. Clinical variables including underlying disease, antibiotic prophylaxis, enema, povidone- iodine cleansing of the rectum, and infectious complications were evaluated. The primary outcome was the post-biopsy infection rate after fluoroquinolone prophylaxis. Univariable and multivariable analyses were used for identification of risk factors for infectious complications.Results: The study included 827 patients, of whom 93 patients (11.2%) reported receiving antibiotics in the previous 6 months and 2.5% had a history of prostatitis. The infectious complication rate was 2.2%. Post-biopsy sepsis was reported in 2 patients (0.2%). In multivariable analysis predictors of post-biopsy sepsis included person performing biopsy (adjusted odds ratio [OR], 4.05; 95% confidence interval [CI], 1.31-12.5; p=0.015) and operation history within 6 months (adjusted OR, 5.65; 95% CI, 1.74-18.2; p=0.004).Conclusions: The post-prostate biopsy infectious complication rate in this study was 2.2%. Person performing biopsy (non-urologists) and recent operation history were independent risk factors for infectious complications after trans-rectal prostate biopsy.

Retroperitoneoscopic Partial Nephrectomy in a Horseshoe Kidney

이용승,유호송,김명업,장호성,이대훈,염찬동,Jong Ho Hwang,함원식 대한비뇨의학회 2011 Investigative and Clinical Urology Vol.52 No.11

A 21-year-old woman with a 4 cm enhancing cystic renal mass in the left moiety of a horseshoe kidney was treated through a retroperitoneal laparoscopic approach. The tumor was excised completely with cold scissors, and renal parenchyma suturing with a surgical bolster was done with Vicryl 2-0 sutures. Choosing the proper approach according to the location of the lesion and the surgeon’s experience with both approaches are of importance in laparoscopic surgery in horseshoe kidney cases. A preoperative kidney computed tomography angiography was helpful for understanding the complex renal vasculature.

Small Renal Masses: Surgery or Surveillance

황의창,유호송,권동득 대한비뇨의학회 2013 Investigative and Clinical Urology Vol.54 No.5

The incidence of kidney cancer has been rising over the past two decades, especially in cases in which the disease is localized and small in size (<4 cm). This rise is mainly due to the widespread use of routine abdominal imaging such as ultrasonography, computed tomography, and magnetic resonance imaging. Early detection was initially heralded as an opportunity to cure an otherwise lethal disease. However, despite increasing rates of renal surgery in parallel to this trend, mortality rates from renal cell carcinoma have remained relatively unchanged. Moreover, data suggest that a substantial proportion of small renal masses are benign. As a result, the management of small renal masses has continued to evolve along two basic themes: it has become less radical and less invasive. These shifts are in part a reflection of an improved understanding that the biology of incidentally discovered renal cell carcinoma may be more indolent than previously thought. However, not all small renal masses are indolent, and de novo metastatic disease can develop at the initial presentation. Therefore, it is with this background of clinical uncertainty and biological heterogeneity that clinicians must interpret the benefits and disadvantages of various clinical approaches to small renal masses.

Embryonic-Natural Orifice Transluminal Endoscopic Surgery Nephrectomy

정우주,유호송,김광현,양승철,나군호,한웅규,전황균 대한비뇨의학회 2009 Investigative and Clinical Urology Vol.50 No.6

We describe our initial experience with embryonic-natural orifice transluminal endoscopic surgery (E-NOTES) nephrectomy in a nonfunctioning kidney. E-NOTES was performed with modified single port access by using a surgical glove and wound retractor. We used several laparoscopic instruments, such as articulating laparoscopic instruments, clips, conventional laparoscopic graspers, and dissectors. The operative time was 80 minutes. There were no intraoperative complications.

Leukemoid Reaction, a Rare Paraneoplastic Syndrome in Urothelial Cell Carcinoma: Is It an Indicator of a Poor Prognosis?

정호석,신보성,유호송,황의창,김선옥,정성일,강택원,권동득,박광성 대한비뇨기종양학회 2015 대한비뇨기종양학회지 Vol.13 No.3

A leukemoid reaction is usually associated with malignancies of the lung, stomach, and thyroid. In contrast, urothelial cell carcinoma is rarely associated with leukemoid reactions, with few cases reported over the past 30 years. Here, we describe a patient with urothelial cell carcinoma who exhibited a leukemoid reaction. The patient had an elevated white blood cell count and experienced a rapid and aggressive clinical course, terminating in death. For urothelial cell carcinoma patients exhibiting a leukemoid reaction, removal of the inciting tumor is the definitive treatment. However, considering the aggressive nature of these tumors, if the patient is unsuitable for radical surgical management, palliative chemotherapy should be considered.
