To investigate whether cells isolated from the upper urinary tract (UTCs) possess stem cell characteristics and could be an alternative cell source for patients with bladder cancer. Current tissue engineering approaches for urologic tissue regeneration require invasive tissue biopsies to obtain autologous cells, and these procedures are associated with potential complications, such as donor site morbidity...
To compare elderly patients undergoing robotic assisted partial nephrectomy (RAPN) with a match cohort of younger patients. Investigating the benefits of minimally invasive RAPN including faster convalescence and decreased postoperative narcotic use make this an attractive option in patients with advanced age and numerous comorbidities. A retrospective review of 250 consecutive patients who underwent...
To evaluate the effect that a safety wire (SW) had on insertion force and direct ureteral trauma using ureteral access sheaths (UAS) in an ex vivo porcine model. UASs were advance into 20 fresh ex vivo porcine kidney-ureters, either with or without SWs. The average and max force of insertion were recorded. Retrograde saline injection was used to identify the presence of lacerations. For SW vs...
To compare the survival outcomes of patients with advanced nonseminoma and extraretroperitoneal (ERP) disease observed for a clinical complete response (CCR) with those demonstrating a pathologic complete response (PCR). From 1989 to 2003, 237 patients with clinical Stage III nonseminoma underwent induction chemotherapy followed by retroperitoneal lymph node dissection. After chemotherapy, 107...
To evaluate the functional outcomes and complications for patients with bladder cancer undergoing robotic-assisted laparoscopic radical cystectomy with Indiana pouch continent cutaneous urinary diversion. From February 2004 to March 2010, 34 patients underwent robotic-assisted laparoscopic radical cystectomy with Indiana pouch continent cutaneous urinary diversion reconstruction. After surgery,...
To evaluate the role of M2 and M3 muscarinic acetylcholine receptor (mAChR) subtypes in the activation of bladder afferent pathways in rats with chronic spinal cord injury (SCI). Adult female Sprague-Dawley rats were spinalized at the T9 level. Continuous cystometry was performed under awake conditions 2 or 4 weeks after SCI. The effects of intravesical administration of an mAChR agonist (oxotremorine-methiodide),...
We present a unique case of incidentally discovered symptomatic, stone-laden ureteroceles after robotic prostatectomy at a high-volume institution. The 2-month postoperative timeline to presentation and laser unroofing management strategy for bilateral ureteroceles after robotic prostatectomy are described.
To determine whether Charlson comorbidity index (CCI) predicts the postoperative complications after percutaneous nephrolithotomy (PCNL) and could be a plausible option to avoid surgery and its potential risks in elderly patients with significant comorbidites. The data from 283 elderly patients (age ≥60 years) who underwent PCNL in 4 large referral hospitals were reviewed in the present multicenter...
To establish prognostic data regarding fetal hydronephrosis using the anteroposterior diameter (APD) and the need for interventional surgery in the Korean population. A total of 187 children with an APD of ≥4 mm on obstetric ultrasound scans at any gestational age were retrospectively reviewed. The affected renal units were divided into 2 groups: surgical and nonsurgical. The ultrasound findings...
To examine the relationship between the mean platelet volume (MPV) and varicocele to clarify the etiopathogenesis of varicocele. MPV levels were measured in 60 varicocele subjects (group I) and 57 healthy controls (group II) from 2009-2010. Ages were similar between the 2 groups. The diagnosis of varicocele was based on the findings from both physical examination and color Doppler ultrasound. ...
To evaluate the feasibility and safety of using the sacro-spinous ligament (SSL) as a fixation point for anterior-apical pelvic floor compartment mesh implants. The apical support achieved with the sacro-spinous ligament mesh fixation is considered adequate, as it provides a high and stronger anchoring point. Even though, meshes for anterior pelvic floor reconstruction are traditionally anchored to...
A 79-year-old man presented with a history of clear cell carcinoma of the right kidney, Fuhrman grade 2, 12 years after nephrectomy, and a history of low-risk prostate adenocarcinoma 11 years after brachytherapy. One year before presentation, the renal cell carcinoma had metastasized to his axial skeleton, and temsirolimus was started. Approximately 1 year later, he presented with a new, painful,...
To compare the gases generated from GreenLight High-Performance System (HPS) laser prostatectomy with Urosol or normal saline solution and transurethral resection and vaporization of the prostate (TURVP) with Urosol. A total of 36 smoke samples were collected from a continuous irrigation suction system attached to a Tenax absorber during transurethral surgery of the prostate. The gases were qualitatively...
To report our results with 1-stage reconstruction in short distal urethral strictures using circular buccal mucosa graft (cBMG). The data of 19 patients (median age 41.8 years, range 25-58) operated between 2001 and 2010 were reviewed. Patients were evaluated with American Urological Association (AUA) symptom score, uroflowmetry, voiding cystourethrography (VCUG), and intraoperative urethroscopy...
