Comparison of Perioperative Outcomes in Patients Undergoing Robotic and Laparoscopic Adrenalectomy
국하림,이정근,오종진,이상철,홍성규,변석수,이상은 대한비뇨기종양학회 2016 대한비뇨기종양학회지 Vol.14 No.3
Purpose: To compare outcomes of robotic adrenalectomy with conventional laparoscopic adrenalectomy. Materials and Methods: This retrospective study included 63 patients who underwent robotic or laparoscopic adrenalectomy between March 2005 and April 2016, with all operations performed using a transperitoneal approach. Outcomes were compared in the 29 patients who underwent robotic adrenalectomy and the 34 who underwent conventional laparoscopic adrenalectomy. Results: Mean age (53.1±12.2 years vs. 51.4±15.1 years, p=0.631) and body mass index (25.9±3.8 kg/m2 vs. 25.2±3.5 kg/m2, p=0.461) were similar in the robotic and laparoscopic groups. A significant percentage of patients in the robotic group had undergone prior abdominal surgery (38% vs. 12%, p=0.015). Mean tumor sizes (3.0±1.5 cm vs. 3.7±2.7 cm, p=0.134) and the percentage of incidentalomas (75.9% vs. 73.5%, p=0.354) were similar in the robotic and laparoscopic groups. There were no statistical significance between-group differences in tumor size, operative time, estimated blood loss, perioperative hemoglobin change, length of hospital stay, and complication rates. Pathologic diagnosis showed that pheochromocytoma (21% vs. 3%) and metastatic tumor (24% vs. 6%) were more frequent in the robotic than in the laparoscopic group (p=0.019). Subgroup analysis of patients with low tumor volume (≤6.8 cm3) showed that operation time was significantly shorter in the robotic than in the laparoscopic group (p=0.045). Conclusions: Robotic adrenalectomy is feasible, with outcomes comparable to those of laparoscopic adrenalectomy.

Purpose: To compare several contemporary urodynamic criteria for diagnosing detrusor underactivity (DU) and estimate how well they coincide with each other. Materials and Methods: From our prospective urodynamic database we identified nonneurogenic lower urinary tract symptoms (LUTS) patients older than 60 years between 2003 and 2014. Patients were reclassified based on four and three contemporary criteria for DU among men and women. Each criterion was compared with the others using the McNemar test. Results: Urodynamic data of 4,372 patients (3,357 men and 1,015 women) were analyzed. In men, the prevalence of DU was estimated to be 56%, 17%, 5%, and 10% based on bladder contractility index, Abrams-Griffith number, maximal detrusor pressure at maximal flow rate (PdetQmax) 30, and bladder voiding efficiency (BVE) criteria. In women, 14.9%, 9.6%, and 6.4% of patients were classified as having DU based on maximal flow rate/postvoid residual (Qmax/PVR), PdetQmax 30, and BVE criteria. For individual subjects, all 4 criteria for men were significantly different from each other, while PdetQmax 30 and BVE criteria for women did not differ significantly (p=0.065). Additionally, BVE criterion for men and PdetQmax 30 and BVE criteria for women could distinguish the differences of patient age, free Qmax and free PVR between patient with and without DU. Conclusions: Each urodynamic criterion for men does not coincide with each other in the diagnosis of DU within individual subjects. On the other hand, PdetQmax 30 criteria and BVE criteria for women could be appropriately applied to clinical practice when diagnosing DU in women with LUTS.

Purpose: The purpose of this article is to report establishment of the 1st Web-based database (DB) system to collect renal cell carcinoma (RCC) data in Korea. Materials and Methods: The new Web-based DB system was established to collect basic demographic and clinicopahtological characteristics of a large cohort of patients with RCC in Korea. Data from a total of 6,849 patients were collected from 8 tertiary care hospitals that agreed to participate in organizing the Korean Renal Cell Carcinoma (KORCC) study group as of 1 July 2015. Basic demographic and clinicopathological characteristics were collected. The data of patients who underwent surgical treatments were analyzed to characterize Korean RCC. Results: We established the 1st Web-based DB of Korean RCC, a database comprising renal mass management cases from multiple centers in Korea. The data of 5,281 patients who underwent surgical management (mean follow-up, 32 months) were analyzed. The most common symptom was incidentally detected renal mass (76.9%). Clinical T1a was the most common (54.3%) stage and mean tumor size was 4.8±4.2 cm. Radical nephrectomy accounted for 62.7% of cases and an open approach was used in 50.7% and 52.2% of radical and partial nephrectomies, respectively. The 5-year overall, cancer-specific and recurrence-free survival rates were 88.1%, 92.2%, and 88.0%, respectively. Conclusions: We report the 1st establishment of a Web-based DB system to collect RCC data in Korea. This DB system will provide a solid basis for the characterization of Korean RCC.
