Urol Res 37:117-9. 2009..Therefore, metal clips should be applied sparingly at the vesicourethral anastomosis during retropubic radical prostatectomy...- Changes of bladder activity and glycine levels in the lumbosacral cord after partial bladder outlet obstruction in ratsMinoru Miyazato
Department of Organ oriented Medicine, Division of Urology, Faculty of Medicine, University of the Ryukyus, Nakagami gun, Okinawa, Japan
Int J Urol 15:843-7. 2008..We investigated the time course of changes in bladder activity as well as in spinal and serum levels of glutamate and glycine after partial bladder outlet obstruction (BOO) in rats... - Investigation of biochemical factors related to non-bothersome nocturnal urinationKimio Sugaya
Division of Urology, Department of Organ oriented Medicine, University of the Ryukyus, Okinawa, Japan
Biomed Res 28:213-7. 2007..In conclusion, nocturnal urination might be not considered bothersome when subjects maintain sufficient levels of melatonin... - Relationship between serum cholinesterase level and urinary bladder activity in patients with or without overactive bladder and/or neurogenic bladderKimio Sugaya
Division of Urology, Department of Organ oriented Medicine, Faculty of Medicine, University of the Ryukyus, Okinawa 903 0215, Japan
