BACKGROUND The aim of the present study was to investigate the impact of the Great East Japan Earthquake on laboratory findings in chronic hemodialysis (HD) patients in Fukushima. METHODS Changes in laboratory findings and cardiothoracic ratio (CTR) between before and after the earthquake were retrospectively analyzed in 90 adult HD patients with(More)
OBJECTIVE To elucidate the etiology of lower urinary tract symptoms (LUTS) after radical prostatectomy, the present study investigated associations between postoperative urethral and vesical anatomic features on magnetic resonance imaging (MRI) and LUTS. PATIENTS AND METHODS Fifty consecutive patients undergoing radical prostatectomy also underwent(More)
Although open retropubic radical prostatectomy has been the most commonly used surgical technique for patients with localized prostate cancer for decades, robot-assisted radical prostatectomy (RARP) has recently become an alternative option and widely used in Japan as well as around the world. RARP has been shown to have higher postoperative continent rates(More)
OBJECTIVE To present a new grouping of male patients with lower urinary tract symptoms (LUTS) based on symptom patterns and clarify whether the therapeutic effect of α1-blocker differs among the groups. METHODS We performed secondary analysis of anonymous data from 4815 patients enrolled in a postmarketing surveillance study of tamsulosin in Japan. Data(More)
Bypass pyeloplasty (BP) is a simple, non-dismembered procedure that is a side-to-side anastomosis without dividing the ureteropelvic junction (UPJ). BP has been considered more suitable especially for novice surgeons than dismembered pyeloplasty via the laparoscopic approach, but not reported. However, the disadvantage of laparoscopic BP is that it is(More)
OBJECTIVES To elucidate the effect of postoperative urinary incontinence on nocturia-related quality of life after robot-assisted radical prostatectomy. METHODS A total of 100 consecutive patients who underwent robot-assisted radical prostatectomy completed a nocturia quality of life questionnaire score and a frequency-volume chart before and after(More)
PURPOSE The aim of the present study is to investigate the effect of pad use for postprostatectomy incontinence on urinary quality of life (QoL) after robot-assisted laparoscopic radical prostatectomy (RARP) in the early postoperative period. METHODS Ninety patients underwent RARP simultaneously completed International Consultation on Incontinence(More)
To compare the postoperative tissue damage and longitudinal changes in functional and patient-reported outcomes after vesicourethral anastomosis with barbed suture and nonbarbed suture in robot-assisted laparoscopic radical prostatectomy (RARP). This was a prospective cohort study involving 88 consecutive patients who underwent RARP. These patients were(More)
OBJECTIVE The aim of the present study is to elucidate factors contributing to early recovery of urinary continence after robot-assisted laparoscopic radical prostatectomy (RARP) from the perspective of urethral and vesical anatomical features after RARP. PATIENTS AND METHODS Sixty consecutive patients undergoing RARP also underwent pre- and postoperative(More)
BACKGROUND When urine output increases, voided volume at each voiding also increases in normal subjects. This is generally understood as a vesical adaptation response to diuresis (VARD). Because lower urinary tract symptoms (LUTS) are supposed to be improved by the change in bladder function after robot-assisted laparoscopic radical prostatectomy (RARP),(More)
