PurposeTo evaluate the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) for extremely large prostates.Materials and MethodsPatients undergoing HoLEP between July 2008 and December 2013 from the Seoul National University Hospital Benign Prostatic Hyperplasia Database Registry were retrospectively analyzed. The patients were divided into three groups according to their total prostate volume (TPV): group A (TPV<100 mL), group B (100 mL≤TPV<200 mL), and group C (TPV≥200 mL); the clinical data of the three groups were compared. All patients were followed up 2 weeks, 3 months, and 6 months after surgery.ResultsA total of 502 patients (group A, 426; group B, 70; group C, 6) with a mean age of 69.0 (standard deviation, ±7.3) years were included in our analysis. The mean prostate volume and prostate-specific antigen level were 68.7±36.9 mL and 4.15±4.24 ng/mL, respectively. The enucleation and morcellation times were longer in group C (p<0.001), and the enucleation efficacy was higher in this group (p<0.001, R2=0.399). Moreover, the mean postoperative catheterization and hospitalization periods were significantly longer in group C (p=0.004 and p=0.011, respectively). However, there were no significant differences between the groups in any other postoperative events, including recatheterization, reoperation, urinary tract infection, clot retention, and bladder neck contracture (p range, 0.516-0.913). One patient in group C experienced recurrence of the urethral stricture.ConclusionsHoLEP in patients with an extremely large prostate can be performed efficiently and safely.
PurposeIn patients with neurogenic bladder due to spinal cord injury or disease who undergo augmentation cystoplasty (AC) for not only bladder dysfunction but also sphincteric incontinence, the need for concomitant bladder neck reconstruction at the time of AC has not yet been established. The aim of this study was to evaluate whether concomitant bladder neck reconstruction is necessary when performing AC.Materials and MethodsWe retrospectively investigated 35 patients who underwent AC from January 2006 to September 2010. Medical history, preoperative and postoperative fluoroscopic urodynamic study (FUDS) parameters, and responses to an incontinence questionnaire (ICIQ Korean version) were reviewed.ResultsA final analysis was performed on 17 patients (9 male, 8 female) who were diagnosed with sphincteric incontinence. Continence status, the number of pads used, and the bother score were significantly improved postoperatively in this subpopulation. Preoperatively, all patients used pads, and the average daily number was 2.2 (median; range 0 to 6). Postoperatively, the number of pads used decreased significantly to 0.9 (median; range 0 to 3) pads a day (p=0.002). Urodynamic parameters including bladder capacity, compliance, involuntary detrusor contraction, and bladder neck incompetence proven by FUDS were also significantly improved.ConclusionsOur study demonstrated that both objective urodynamic parameters and subjective incontinence symptoms improved significantly after the completion of AC as a single procedure in patients with sphincteric incompetence. This implies that anti-incontinence bladder outlet surgery does not have to be performed simultaneously and can be considered later as a staged operation.
PurposeSince the 1990s, it has been well known that orchiopexies should be performed by no later than 2 years of age. Nevertheless, studies from other countries report a substantial number of delayed orchiopexies. On the basis of an analysis of a tertiary care hospital database, we aimed to investigate the incidence of delayed orchiopexies performed in patients after 5 years of age and to understand the causes of such delays and the possible consequences.Materials and MethodsWe retrospectively analyzed the surgical database of Seoul National University Hospital between 2004 and 2012 and detected patients who underwent orchiopexy later than 5 years of age. Reasons for delayed orchiopexies were studied and the possible consequences of delayed orchiopexies were assessed with respect to surgical difficulty and testicular volume.ResultsWe found 160 cases of delayed orchiopexies, which accounted for about 15% of all orchiopexies performed. Two major reasons for delay were related to the parents of the child: parental delay and parental request for the treatment of persistent retractile testis. Acquired cryptorchidism was found in 21 cases (13.1%), mainly associated with hypospadias. Surgical difficulty, especially owing to a short testicular cord, was encountered in 48 cases (30.2%), and a comparison with age-matched normative values showed substantially smaller testicular volume.ConclusionsDespite well-established guidelines for the optimal age of surgery, 15% of orchiopexies were not performed at a proper time. Improved propagation of an optimal age limit is necessary to reduce the rate of delayed orchiopexies considering increases in surgical difficulty and potential testicular growth retardation.
We aimed to investigate the clinical value of persistent but downgraded vesicoureteral reflux (VUR) after dextranomer/hyaluronic acid (Dx/HA) injection in children. The medical records of 128 children (195 ureters) who underwent Dx/HA injections for VUR were reviewed. The incidences of pre- and post-operative febrile urinary tract infections (UTIs) were analyzed in children with or without persistent VUR on voiding cystourethrography (VCUG) 3 months postoperatively. The surgical results of VUR persistent children who underwent a single additional injection were assessed. The VUR resolved completely in 100 ureters (51.3%), was persistent in 95 ureters, and newly developed in 2 ureters. The incidence of pre/post-operative febrile UTIs were 0.35 ± 0.39 per year and 0.07 ± 0.32 per year in VUR resolved children (P < 0.001), and 0.76 ± 1.18 per year and 0.20 ± 0.61 per year in VUR persistent children (P < 0.001). A single additional Dx/HA injection (44 ureters) resolved VUR in 29 ureters (65.9%), and also reduced the VUR to grade I in 7 ureters (15.9%), II in 4 (9.1%), and III in 4 (9.1%). Even in children with persistent VUR after Dx/HA injection, the incidence of febrile UTIs decreased markedly. The VUR grade significantly decreases after single additional Dx/HA injection.
