To report our initial experience with robot-assisted laparoscopic extravesical ureteral reimplantation using the advancement technique.A total of 15 ureters from nine patients (age range 2-25 years) underwent for management vesicoureteral reflux. The reflux was classified as grade I in one ureter, II two ureters, III seven IV three and V ureters. One five female had a bilateral duplex system, observed all four da Vinci surgical system utilized. Ureteral carried out cases. We also compared...
Objectives: In hypospadia patients, the urethral plate and underlying tissue were previously thought to be main cause of penile curvature and, because this, they used excised correct curvature. Currently, are preserved as not anymore. The aim present histology study was elucidate characteristic structure beneath plate. Methods: experimental group consisted 27 hypospadiac patients with moderately severe curvature, who underwent one‐stage urethroplasty after dividing Excised tissues observed...
In cryptorchidism, germ cell development failure presents from infancy and may be reflected by altered hormonal levels produced Sertoli cells. Our object was to assess for associations between serum hormone testicular histopathology in cryptorchidism with an infertility risk according the pretreatment undescended positions.Prepubertal cryptorchid boys aged 7-91 (median 20) months who underwent orchidopexy 2014 2019 were included (122 unilateral [median 19 {range 7-91}], 23 bilateral [24...

Robot-assisted radical prostatectomy (RARP) is commonly performed using the transperitoneal (TP) approach with six trocars over an 8-cm distance in steep Trendelenburg position. In this study, we investigated feasibility and benefit of extraperitoneal (EP) a 4-cm flat or 5° We also introduced four new steps to surgical procedure compared results complications between EP TP propensity score matching. Between August 2012 2016, 200 consecutive patients without any physical restrictions...
Cryptorchidism is known to impair spermatogenesis. The blood-testis barrier (BTB) becomes defined in seminiferous tubules around puberty and provides a suitable environment for germ cells. Little about the BTB undescended testes (UDT).To determine role of during UDT using non-surgical cryptorchid rat model.Unilateral male rats were intraperitoneally injected with non-steroidal antiandrogen intrauterine development; harvested at 4, 5, 6 weeks after birth. Testicular histology, expression...
We present the case of a 12-year-old girl with vesicoureteral reflux (VUR) solitary kidney treated using modified hydrodistention implantation technique. A needle was set parallel to ureteral guidewire inserted through orifice before performing injections correct VUR. Multi-site tandem were administered along wire, which confirmed direction and length tunnel. The mounds aligned without kinking. reduced volume dextranomer-hyaluronic acid copolymer (Deflux®) required construct an effective...
The most common pediatric renal neoplasm is Wilms tumor, but clear cell sarcoma of the kidney or synovial are also sometimes encountered. Accurate pathological diagnosis important, because adjuvant therapies including chemotherapy and radiotherapy differ according to type. A 9-year-old boy presented with a headache, ultrasonography, computed tomography, magnetic resonance imaging revealed heterogeneous enhancement soft tissue originating from upper pole left kidney, measuring approximately...
Abstract Hemiscrotal agenesis is among the rarest anomalies in scrotal development disorders. As it has only been reported three cases, clinical manifestations remain unclear. We report a case of hemiscrotal with ipsilateral cryptorchidism. Based on thermal assessment scrotum, concurrent scrotoplasty and orchiopexy were carried out, improved environment fixed left testis. Furthermore, low expression androgen receptor steroid‐5‐alpha‐reductase, alpha polypeptide 2 affected side scrotum likely...
To identify the causes of vanishing testis besides vascular events secondary to testicular torsion.A total 102 boys with were treated in our hospital from 1984 2011. Of these cases, 91 nubbins excised. Immunohistochemical analysis was carried out using anti-Wilms tumor 1 antibody, which is a stable marker Sertoli cells. Reverse transcription polymerase chain reaction also Wilms 1-specific primers.Most associated inguinal lesion (51 patients, 56.0%). Light microscopy showed that 11 patients...
Gonocytes differentiate into spermatogonial stem cells, which make it possible to maintain spermatogenesis continuously throughout life. We previously reported attenuated cell activity in cryptorchid testes, resulted altered and affected fertility. However, few groups have examined the differentiation process from gonocytes cells. To clarify underlying mechanisms comprehensively we performed microarray analysis assess differential expression of transcripts between normal undescended testes...
We evaluated the association of hypospadias and 17 susceptibility loci previously identified by a European genome-wide study in cohort Japanese patients. also examined expression candidate genes male mouse embryos to determine possible underlying mechanisms this disease.We enrolled 169 patients (mean age at surgery 3.7 years) who underwent repair hypospadias. Genotyping single nucleotide polymorphisms was performed using multiplex polymerase chain reaction invader assay. situ hybridization...
Here, we report the case of a 62-year-old man with neuroblastoma, which is extremely rare in adults. His tumor was resected, but it recurred four months later. Radiotherapy reduced size, and patient remained good health three years after surgical removal. The residual treatments administered to this were evaluated. We have also reviewed literature.
Abstract Background Myelomeningocele, which causes a neurogenic bladder, is usually treated with anticholinergics in children detrusor overactivity (NDO); however, cause side effects such as dry mouth, constipation, attention deficit, and inadequate reduction leak point pressure. Vibegron, novel selective beta-3 adrenoreceptor agonist, well-established alternative to adults an overactive bladder. It remains unknown whether this agent can be used for pediatric patients. We report the case of...
Accessory scrotum is an unusual developmental anomaly defined as additional scrotal tissue in addition to a normally developed scrotum. The accessory arises posterior the located and does not contain testis. We report case of 18-month-old boy with attached perineal lipoma. resected both determined histologically that they were same scrotum, including presence androgen receptor expression. To best our knowledge, this first assess expression using immunostaining.
