Background: This study reviewed the outcomes for patients who underwent simultaneous bladder and ureter reconstructive surgery using the ileum after radical treatment for cervical cancer.
Methods: The medical records of seven patients who underwent augmentation ileocystoplasty with ileal ureter replacement between September 2006 and May 2013 were reviewed. Data on indications for surgery, underlying urologic comorbidities, type of ureteral replacement, postoperative complications, and changes in renal function were obtained.
Effect of Pubovesical Complex Reconstruction During Robot-Assisted Laparoscopic Prostatectomy on the Recovery of Urinary Continence.

Objective: To assess whether pubovesical complex (PVC) reconstruction (termed Kim's stitch) improves urinary continence following robot-assisted laparoscopic prostatectomy (RALP).
Patients And Methods: The cohort consisted of 130 consecutive patients who underwent RALP in a tertiary-care hospital between July 2012 and June 2013. The first 70 patients did not undergo PVC reconstruction with Kim's stitch and formed the control group.
The objective of this study was to evaluate the risk of recurrence in patients with intermediate-risk non-muscle-invasive bladder cancer (NMIBC) after intravesical instillation with chemotherapeutic agents or Bacillus Calmette-Guérin (BCG) therapy. A cohort of 746 patients with intermediate-risk NMIBC comprised the study group. The primary outcome was time to first recurrence.

Materials And Methods: We included 67 consecutive patients treated by a single surgeon between June 2011 and November 2014 with hand-assisted laparoscopic bladder cuff excision through the same hand port as that used for nephroureterectomy. We retrospectively analyzed procedure-related clinical data and short-term oncologic outcomes.
Purpose: To evaluate the validity of hand-assisted laparoscopic partial nephrectomy (HALPN) for small renal masses, patients who underwent HALPN, robot-assisted laparoscopic partial nephrectomy (RALPN), or open partial nephrectomy (OPN) at a single medical institution were compared in terms of perioperative outcomes.
Patients And Methods: In this retrospective cohort study, all 590 consecutive patients who underwent HALPN (n=89), RALPN (n=147), or OPN (n=354) between July 2011 and April 2014 in a single institute were compared in terms of perioperative outcomes, including the mean operative time, warm ischemia time (WIT), length of the hospital stay, change in the estimated glomerulofiltration rate (eGFR), duration of analgesic use, surgical margins, and adverse events. The patient groups were compared by a multivariate regression model, in which adjustments were made for differences in baseline demographic and tumor characteristics.
Purpose: To report complications, including three types of fistula, intractable hematuria, and pain, which can develop after polymeric ureteral stent (PUS) or metallic ureteral stent placements and to evaluate the risk factors for these adverse events.
Patients And Methods: We reviewed seven patients referred to our trauma and reconstructive subdivision for complications that presented after placement of a PUS (two patients), double-layered, coated, self-expandable, mesh metallic stent (three patients), Memokath stent (one patient), or Resonance stent (one patient). We retrospectively reviewed their medical records and accessed the predisposing factors, mechanism of injury, diagnosis, and interventional and surgical management.
Objectives: To investigate the association between body mass index and clinicopathological features of bladder cancer, and to assess the prognostic value of body mass index in patients undergoing radical cystectomy for bladder cancer.
Methods: The medical records of 714 patients who underwent radical cystectomy for bladder cancer were reviewed. The association of body mass index at surgery with clinicopathological features was examined, and the prognostic value of body mass index for recurrence-free survival and cancer-specific survival was analyzed using the Kaplan-Meier method and Cox regression models.
Purpose: We evaluated the number of cases necessary to develop competence for performing laparoscopic radical nephrectomy (LRN) by chronologically analyzing the results of 150 cases.
Patients And Methods: 150 patients were included in this study, each of whom had had pure transperitoneal LRNs between March 2003 and February 2008 performed by three surgeons who were all novices in laparoscopic surgery. Each surgeon performed 50 LRNs.
Aims: The aim of this study is to compare the urodynamic parameters in ischemic and hemorrhagic stroke patients with bladder dysfunction.
Materials And Methods: We retrospectively reviewed medical records such as computed tomography (CT) or magnetic resonance imaging (MRI) and urodynamic study and identified 84 cases among 150 stroke patients underwent urodynamic test due to lower urinary tract symptoms (LUTS) from June 2003 to May 2008. Exclusion criteria are diabetes mellitus (DM) cystopathy, previous pelvic surgery, spinal cord injury, benign prostate hyperplasia (BPH), and other neurologic etiology.
Background And Purpose: Electrodes used by the Sonolith Vision lithotripter have a specified lifespan, and the manufacturer recommends replacing the electrode every 35,000 shocks. To evaluate the efficacy of extracorporeal shockwave lithotripsy (SWL) as it relates to electrode lifespan, and establish standard treatment results, we performed an in vitro study.
Materials And Methods: From August to October 2005, 12 sessions of shock testing were performed by a Sonolith Vision lithotripter using four test stones per month.
