To compare the impact of transurethral resection of prostate (TURP) on symptom scores and maximal flow rates (Qmax) in patients with equivocal bladder outlet obstruction (BOO) and definite BOO and to assess the relationship between the surgical outcomes and degree of preoperative BOO, we prospectively evaluated men with lower urinary tract symptoms and bladder outlet obstruction index (BOOI) gr...

In this report, we describe the cloning and characterization of Boo, a novel anti-apoptotic member of the Bcl-2 family. The expression of Boo was highly restricted to the ovary and epididymis implicating it in the control of ovarian atresia and sperm maturation. Boo contains the conserved BH1 and BH2 domains, but lacks the BH3 motif. Like Bcl-2, Boo possesses a hydrophobic C-terminus and locali...

OBJECTIVE To analyze the lower urinary tract symptoms (LUTS) and video-urodynamic characteristics of women with clinically unsuspected bladder outlet obstruction (BOO). METHODS From 1997 to 2010, a total of 1605 women with bothersome LUTS received video-urodynamic study in our unit. We reviewed the charts of 212 women diagnosed with BOO based on video-urodynamic criteria and 264 women without...

PURPOSE We investigated the effects of mirodenafil, a phosphodiesterase-5 inhibitor developed in South Korea, on the female rat bladder in a partial bladder outlet obstruction (BOO) model. MATERIALS AND METHODS Thirty-six female Sprague-Dawley rats were divided into four groups: the control group, BOO without medication group, BOO with mirodenafil 1 mg/kg group, and BOO with mirodenafil 4 mg/...

OBJECTIVE To demonstrate the significance of bladder outlet obstruction (BOO) in preoperative urodynamic studies (UDS) in women who have been diagnosed with pelvic floor dysfunction including pelvic organ prolapsed (POP) and stress urinary incontinence (SUI). METHODS The medical records of 150 patients with pelvic floor dysfunction who underwent preoperative UDS at Yonsei University Health Sy...

AIMS Bladder outlet obstruction (BOO) can mediate structural and functional detrusor changes, which can lead to bothersome lower urinary tract symptoms. We investigate if sacral nerve stimulation (SNS) can prevent these structural and functional changes in a rat model of BOO. METHODS 24 female Sprague-Dawley rats (250 gm) were divided into 4 groups: control (CTRL), BOO, SNS, and both (BOO/SNS...

PURPOSE To investigate the lower urinary tract changes in mice treated with L-NAME, a non-selective competitive inhibitor of nitric oxide synthase (NOS), or aminoguanidine, a competitive inhibitor of inducible nitric oxide synthase (iNOS), after 5 weeks of partial bladder outlet obstruction (BOO), in order to evaluate the role of constitutive and non-constitutive NOS in the pathogenesis of this...

Objective Men with benign prostate hyperplasia (BPH) with good urinary flow may still have bladder outlet obstruction (BOO). Intravesical prostatic protrusion (IPP) has been shown to be able to predict BOO. We aim to investigate the use of IPP to predict BOO in men with good urinary flow. Methods One hundred and fourteen consecutive men (>50 years old) presenting with lower urinary tract symp...

PURPOSE In women who reported a weak urinary stream, the efficacy of treatment chosen according to the urodynamic findings on pressure-flow study was prospectively evaluated. MATERIALS AND METHODS Twelve female patients with maximum flow rates of 10 mL/sec or lower were analyzed in the present study. At baseline, all underwent pressure-flow study to determine the degree of bladder outlet obst...
