We investigated factors determining the degree of functional reduction by measuring changes in individual renal function before and after partial nephrectomy.In 117 patients who underwent elective nephrectomy glomerular filtration rate units with tumor from diethylenetetramine pentaacetic acid scan was measured at a mean 6.5 months surgery. Kidney volume calculated using computerized tomography. Of these 52 65 open laparoscopic nephrectomy, respectively. Satinsky clamps were used for...
The effects of sunitinib in a broad patient population, especially those Asian ethnicity, have been rarely investigated. Here, we assessed the efficacy and safety Korean patients with advanced renal cell carcinoma.Between April 2006 August 2008, 77 carcinoma were treated sunitinib. We performed retrospective analysis for terms survival outcomes response rate. Toxicity profiles also assessed.A total 65 patients, including 39 (60%) without previous cytotoxic or immunotherapy, eligible...

Abstract The World Health Organization/International Society of Urological Pathology (WHO/ISUP) grading renal cell carcinoma (RCC) is classified from grade 1–4, regardless subtype. National Comprehensive Cancer Network (NCCN) guidelines (2022) state that if there an adverse pathological feature, such as 3 or higher RCC in stage 1 patients, more rigorous follow-up imaging recommended. However, the do not provide specific treatment policies by tumor grade. Therefore, this study attempted to...

We investigated whether tumor location has independent prognostic significance in upper tract transitional cell carcinoma cases and which factor determines it.We reviewed data on 122 renal pelvis 102 ureteral cases, including the recurrence pattern. Tumor other clinicopathological variables were evaluated regarding cancer specific recurrence-free survival. Stage pT3 tumors stratified into those invading parenchyma or peripelvic/periureteral fat.Overall 5-year survival rates 77.0% 71.6%,...
ABSTRACT Objectives This phase I trial evaluated the RUS 3D virtual surgical navigation system's feasibility during robot‐assisted partial nephrectomy. Methods In ten patients who underwent nephrectomy at Asan Medical Center, a anatomical model was reconstructed from preoperative computerized tomography scans. The integrated with surgeon's console through TilePro, providing manipulable anatomy surgery. Following standard procedures performed by single experienced surgeon using system,...
Purpose: Determining the optimal surgical approach for patients with T1 renal tumors requires balancing long-term oncological and functional outcomes. Using machine learning algorithms, we aimed to develop a model predict both outcomes simultaneously, according each radical (RN) partial nephrectomy (PN).Materials Methods: demographic preoperative variables of 823 clinical T1N0M0 who underwent PN or RN between 2007 2019, employed 5 different algorithms—general linear (GLM), extreme gradient...
Von Hippel-Lindau (vHL) disease encompasses various genetic subtypes with poorly defined progression patterns. This retrospective study of a longitudinal cohort aimed to characterize follow-up duration, treatment rates, and patterns according genomic subtype, identify risk factors for progression. Between June 2003 2020, the enrolled 94 patients (mean age, 37.1 years; 49 females; 84 missense mutations 10 truncating (i.e., insertion/deletion) in VHL tumor suppressor gene). MRI CT imaging data...
To investigate and compare changes in the bladder function after radical prostatectomy (RP) to correlate subjective voiding symptoms with observed function.In 72 patients who had RP between 2003 2004, we serially evaluated urodynamic studies (UDS) before at 3, 6 36 months afterward. The short-form International Continence Society-male symptom questionnaire was also repeated corresponding periods. Changes contraction storage were compared for symptoms.On serial UDS, there reductions maximum...
Purpose:The prognosis of patients with malignant pheochromocytoma is poor, but the predictive factors are not well understood.We aimed to identify clinical characteristics malignancy after initial surgical removal in pheochromocytoma. Materials and Methods:We retrospectively reviewed records 152 diagnosed pheochromocytoma, including 5 (3.3%) metastasis at time excision 12 (7.9%)who developed during follow-up.To determine malignancy, we compared clinical, radiographical, urinary chemical...
It is controversial that perinephric fat infiltration has an impact on survival in patients with renal cell carcinoma. Therefore, we evaluated the influence of and tumor size patient survival.We retrospectively reviewed medical records 783 77 pT1-2 (cN0M0) pT3a carcinoma, respectively. Sporadic unilocular noncystic carcinoma was included. Univariate multivariate analyses prognostic factors, including infiltration, cancer specific disease-free were performed. Median followup 56.0 months after...
We evaluated the additional usefulness of multiphase computerized tomography for improving differential diagnosis cystic renal masses by Bosniak classification.We reviewed records 104 patients with class II (29 or 27.8%), III (38 36.5%) and IV (37 35.7%) managed surgically between 1997 2007. On preoperative enhancement differences in HU precontrast corticomedullary phases were measured at highest area to correlate pathological findings.Renal cell carcinoma was diagnosed 56 (53.8%). Of tumors...
We assessed the change in unilateral renal function after laparoscopic partial nephrectomy to determine factors affecting course and predicting postoperative glomerular filtration rate decrease.From prospectively collected data on 116 patients who underwent we evaluated of operated kidney using diethylenetriaminepentaacetic acid scans done preoperatively, 3 months, 1, 2 years postoperatively. Kidney volume was measured from arterial phase dynamic computerized tomography before months...
Study Type – Diagnostic (exploratory cohort) Level of Evidence 2b What’s known on the subject? and What does study add? Multilocular cystic renal cell carcinoma (MCRCC), defined according to 2004 WHO classification, has good prognosis, which is not affected adversely by large tumour size or advanced stage. Thus nephron‐sparing surgery proposed when MCRCC suspected preoperative radiologic criteria. The present confirms low malignant potential MCRCC. Additionally, results provide a simple,...
The aim of the study is to identify pre-operative variables for selection patients who would benefit from upfront cytoreductive nephrectomy metastatic renal cell carcinoma. We reviewed medical records 171 were presented with synchronous carcinoma and had received no systemic therapy before enrollment. Of these, 96 underwent followed by targeted (cytoreductive group) 75 treated alone (non-cytoreductive group). A Cox proportional hazards regression model was used estimate prognostic...
