Paraneoplastic hypertension associated with a renal oncocytoma is an unreported syndrome. We report a unique case of a patient with multidrug-resistant hypertension who was found to have a solitary renal mass. Cryoablation was performed and resulted in an immediate and dramatic decrease in blood pressure. Histologic review of intraoperative biopsy specimens revealed findings consistent with renal...
To test the hypothesis that hyperbaric oxygen (HBO) has no effect on tumor growth in a murine model of indolent in vivo prostate cancer. HBO means breathing pure (100%) oxygen under increased atmospheric pressure.Human prostate PC-3 cells were injected into 40 severe combined-immunodeficient mice. They were randomized to undergo 20 sessions of either HBO or normobaric air in standardized conditions...
To examine the effect of concurrent statin use during definitive radiotherapy (RT) on the biochemical outcomes for localized prostate cancer.A total of 968 patients treated with RT had information about medication use available. Of these, 23% had been taking using statins during RT. Progression-free survival (PFS) was determined by a biochemical failure definition of prostate-specific antigen nadir...
To analyze the clinical value of C-reactive protein (CRP) as a marker of prolonged hospitalization and a predictor of recurrence in patients after uncomplicated acute pyelonephritis (APN).A total of 202 consecutive adult patients with APN were prospectively enrolled from September 2005 to June 2007. APN was defined as the concomitant presence of 4 major and ≥2 minor clinical or laboratory signs or...
Optical reflectance spectrophotometry (ORS) is part of a group of novel techniques that have demonstrated promise for the assessment and differentiation of various solid tumors. In this study, we evaluated the ability of ORS to differentiate malignant from benign kidney tumors at surgery.From January to April 2007, we completed optical spectroscopy measurements (OSM) at several standardized tumoral...
To present a comprehensive experience with intraprostatic botulinum toxin (BT) injection in men with symptomatic benign prostatic hyperplasia (BPH).In this open-label study using an outpatient setting, 77 men with BPH received 200 intraprostatic BT A units (Botox) using an ultrasound-guided transperineal approach. We evaluated the American Urological Association (AUA) score, serum prostate-specific...
Testicular torsion can be extravaginal, intravaginal, or mesorchial. Mesorchial torsion is less well defined and has an atypical presentation. Here we present the case of a 13-year-old with severe, intermittent right scrotal pain, erythema, and a large hydrocele. Color Doppler ultrasound examination showed epididymal enlargement and normal flow. Weeks after presentation, serial color Doppler ultrasound...
To evaluate the effectiveness of a lingual mucosal graft (LMG) urethroplasty for anterior urethral strictures and the donor site complications.A total of 30 patients underwent urethroplasty for anterior urethral strictures using dorsal on-lay of a LMG from March 2006 to December 2006. Most patients had balanitis xerotica obliterans as the etiology. The mean stricture length was 10.2 cm (range 3.7-16...
To determine the incidence and characteristics of incidental prostate cancer diagnosed by cystoprostatectomy (CPT) in Korean men.Thirty-six consecutive male patients scheduled to undergo CPT were prospectively enrolled. The CPT specimens were examined and the clinicopathologic characteristics of incidental cancers compared with those of T1c prostate cancers that had undergone radical prostatectomy...
Port site and local recurrences are rather rare, especially after laparoscopic excision of renal malignancies. In addition to the known risk factors, including inappropriate surgical technique and specimen removal, the tumor biology is important. Renal plasmacytomas are rare manifestations of plasma cell tumors. We report a case of port site and local tumor recurrence of a solitary renal plasmacytoma...
Recent laser techniques for the treatment of benign prostatic obstruction result in a significant amount of vaporization. Therefore, less tissue is retrieved for histologic evaluation. This might be an argument in favor of monopolar transurethral resection of the prostate (TURP). The aim of this retrospective study was to determine the ability to detect prostate cancer (PCa) in the TURP specimen of...
Spaceflight-induced microgravity appears to be a risk factor for the development of urinary calculi, resulting in urolithiasis during and after spaceflight. Calcifying nanoparticles, or nanobacteria, multiply more rapidly in simulated microgravity and create external shells of calcium phosphate. The question arises whether calcifying nanoparticles are nidi for calculi and contribute to the development...
To investigate the effect of long-term administration of oxybutynin on afferent input from the bladder by evaluating c-Fos expression in the spinal cord.Using an osmotic pump, long-term administration of oxybutynin (4 weeks) was performed in the rat. The effects of oxybutynin (2 doses) on the urodynamic parameters were determined by continuous cystometry in conscious rats. After cystometry, c-Fos...
To estimate the prevalence of overactive bladder (OAB) in Korean children, 5-13 years of age, and to assess the associated factors for OAB.A randomly selected cross-section study was conducted in 26 kindergartens and 27 elementary schools nationwide in Korea. A total of 19 240 children were included; a parent was asked to complete the questionnaires, which included items about OAB and voiding and...
