To re-assess the Charlson Comorbidity Index (CCI) and the American Society of Anesthesiologists Physical Status Classification System (ASA grade) as predictive factors of complications after transurethral resection of prostate.This study retrospectively included and analyzed consecutive patients undergoing transurethral resection of the prostate at Peking University First Hospital between 1992 and...
To retrospectively assess that over the 2 decades, whether medical therapy has changed indications, patient characteristics, and outcomes in men undergoing transurethral resection of the prostate (1992-2013).At our institution, medical history of all patients undergoing surgery before 1998, between 2001 and 2003, and between 2011 and 2013 was reviewed. Patient demographics, preoperative clinical profile,...
To describe a novel technique using extracorporeal tailoring and an inverted ureteral nipple to perform laparoscopic transperitoneal ureteral reimplantation for adult obstructed megaureter and our initial experience with 10 patients.Ten patients (mean age 39.2 years [range, 21-62]) with adult obstructed megaureter underwent transperitoneal laparoscopic ureteral reimplantation by a 3- or 4-port technique...
To compare the efficacy of the doxazosin gastrointestinal therapeutic system (doxazosin-GITS) 4 mg and tamsulosin 0.2 mg on nocturia in Chinese men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH).Data were analyzed from a prospective, multicenter, randomized, open, parallel study of Chinese men aged 50-84 years with LUTS/BPH. Two hundred patients were randomized...
To investigate the effects of artery-ligating varicocelectomy (ALV) and artery-preserving varicocelectomy (APV) on the ipsilateral epididymis of varicocele-induced rats.A total of 50 adolescent male rats were randomly divided into the 4 groups: control group (n = 8), experimental varicocele (EV) without treatment (EV group, n = 14), EV with ALV (ALV group, n = 14), and EV with APV (APV group, n =...
To evaluate whether the bladder size on the voiding cystourethrogram (VCUG) might be a proxy for voiding abnormalities. Voiding abnormalities have been implicated in the development of hydronephrosis, reflux, and urinary tract infections. We evaluated the volume of contrast infused for 617 consecutive VCUGs. We compared the actual volume infused during the VCUG to the expected bladder capacity...
To evaluate the effect ovariectomy (OVX) after 2 and 4 weeks on bladder function and biochemistry of the adult female rabbit urinary bladder.Twelve mature female rabbits were divided into 3 groups: control, 2-week ovariectomized, and 4-week ovariectomized. At the end of the experimental period, the following studies were performed: contractile studies on isolated strips; examinations of the activity...
To determine the efficacy of coenzyme Q10 (CoQ10) and alpha-lipoic acid (α-LA), either alone or in combination, to protect the contractile responses of the rabbit urinary bladder from damage caused by repetitive stimulation in the presence or absence of in vitro ischemia.Four groups of New Zealand white rabbits (4 per group) were treated with vehicle (group 1), CoQ10 (group 2), α-LA (group 3), or...
To determine whether low-dose estrogen supplementation is as effective as high-dose supplementation in increasing bladder contractile function and mediating bladder hypertrophy and angiogenesis.Sixteen New Zealand white female rabbits were separated into four groups of 4 rabbits each. Group 1 served as the control, and groups 2 to 4 underwent ovariectomy. The group 2 rabbits were studied 7 days after...
We examined the expression of Rho-kinase (ROK) isoforms in young and old rabbits’ detrusor smooth muscles (SM) during the progression of short-term partial bladder outlet obstruction and correlated them with the time course of obstruction.We obtained detrusor samples from bladders after 1, 3, 7, and 14 days of obstruction and also sham-operated control rabbits. We used reverse transcriptase–polymerase...
Recent evidence indicates that ischemia and reperfusion (free radical generation) are major etiologic factors in the rabbit bladder subjected to partial outlet obstruction. The current investigation was designed to determine the time course of damage caused by reactive oxygen species (ROS) and reactive nitrogen species (RNS) by measuring the carbonyl and nitrotyrosine content of the bladder.Male rabbits...
To compare the safety and cost-effectiveness of ureterorenoscopic holmium:yttrium-aluminum-garnet (YAG) laser lithotripsy (URSL) with extracorporeal shock wave lithotripsy (ESWL) for proximal ureteral stones. This investigation assessed 220 patients with upper ureteral stones. Those in the ESWL group were treated on an outpatient basis using the Medispec Econolith 2000 (Medispec, Germantown, Md)...
