Vesicoureteral reflux (VUR) is one of the significant urologic diseases of childhood and its endoscopic treatment is a viable option in terms of both simplicity and reduced morbidity. However, despite intensive research, no ideal injection material that yields the best long-term results with the least side effects has been introduced as yet. Synthetic(More)
AIM To review our long-term results of the sub-ureteric injection of calcium hydroxyapatite in the endoscopic management of vesicoureteral reflux (VUR) in children. MATERIALS AND METHODS A sub-ureteric injection of calcium hydroxyapatite was given to 14 children (23 ureteral units) affected by VUR grades I-V. All children were followed-up with monthly(More)
PURPOSE Our aim was to study the effect of chronic ischemia on bladder contraction and detrusor smooth muscle reactivity. The relationship between structural damage and functional changes in the chronically ischemic bladder was also investigated. MATERIAL AND METHODS Male New Zealand White rabbits were divided into arterial injury (AI),(More)
PURPOSE A subset of newborns with myelodysplasia have normal bladder function on urodynamic assessment. We analyzed long-term followup in this population to determine the necessity for subsequent urological surveillance. MATERIALS AND METHODS We retrospectively analyzed the records of 25 of 204 newborns (12%) with myelodysplasia in whom neurourological(More)
Findings on transrectal ultrasonography (TRUS), computerized tomography (CT), and magnetic resonance imaging (MRI) in local staging of prostatic carcinoma (PCa) were compared with the final pathological staging in 30 patients who underwent radical prostatectomy. We found TRUS and MRI to have the same accuracy rate (53%) in local staging, whereas CT revealed(More)
PURPOSE The overall goal was to determine whether chronic ischemia and hypercholesterolemia interfere with bladder function and structure. The roles of atherosclerosis-induced chronic ischemia and hypercholesterolemia in bladder fibrosis and non-compliance were studied in the rabbit. The relationship between ischemia-induced changes in the expression of(More)
CONTEXT Surgical nonautologous meshes have been used for several decades to repair abdominal wall herniae. Implantable materials have been adopted for the treatment of female and male stress urinary incontinence (SUI) and female pelvic organ prolapse (POP). OBJECTIVE A consensus review of existing data based on published meta-analyses and reviews. (More)
Extracorporal shockwave lithotripsy of lower caliceal stones is often unrewarding because of the difficulty of passing stone fragments. We report our results in SWL of lower pole stones in 219 patients and compare them with the results of SWL of middle (82 patients) and upper pole (85 patients) stones. The stone-free rate of SWL monotherapy was found to be(More)
Clitoral and vaginal engorgement during sexual stimulation depend in part on the increase of arterial inflow. It has been shown that apomorphine (APO), a non-selective dopamine receptor agonist, produces penile erection by activating dopaminergic receptors in the central nervous system. Our aim was to study whether systemic administration of APO improves(More)
PURPOSE The correlation between timing of the primary neurosurgical repair and urological prognosis in infants with open spinal dysraphism remains unknown. We investigated the impact of primary repair timing on neurogenic bladder prognosis in children with myelomeningocele. MATERIALS AND METHODS We retrospectively reviewed the records of 401 children with(More)
