The term hypospadias is first time met in the papers of Galen. The word is derived from the Greek words hypo, meaning under and spadon, meaning fissure. The first description of hypospadias, definition of pathology and suggestions for treatment were gave by Helidorus and Antyllus in the first century. They suggested partial resection of glans in or...

Background: Vesicoureteral reflux is diagnosed in one third of children who present with a urinary tract infection. There is no general agreement as to what constitutes the optimum management of children with vesicoureteral reflux, even-though there have been a number of studies prospectively comparing medical and surgical management of reflux. The...
Article
To investigate differences in maturation of germ cells in cryptorchid testes in three different regions. A total of 103 consecutive patients were operated for unilateral undescended testis in Vojvodina, from March 2006 until September 2007, and had a testicular biopsy performed. Germ cells were counted, and the presence of Ad spermatogonia was note...
Article
Acute scrotal pain sometimes requires prompt surgical intervention and therefore accurate diagnosis of different etiologies of acute scrotal pain has great therapeutical and prognostic significance. The aim of this study was to analyze the incidence, symptomatology and results of treatment of acute scrotal pain in children. The study included patie...

We review our thirteen years' experience with the endoscopic treatment of primary vesicoureteric reflux (VUR). We retrospectively reviewed the charts of 81 patients with primary vesicoureteric reflux who were treated endoscopically. The study included 61 girls and 20 boys aged 3 - 15 years. Twenty-eight patients had unilateral reflux, and 53 patien...

Of all children born with congenital anomalies, 30-40% have urogenital abnormalities. Most of them are asymptomatic, but if any symptoms occur, they are usually symptoms of urinary infections. A four-year old girl was admitted because of recurrent urinary infections and in order to perform a thorough clinical examination. Clinical examination showe...

External genital abnormalities represent the most common congenital anomalies. Proper, not delayed diagnosis and treatment of certain abnormalities (undescended testis, hypospadia, varicocele) is of great importance for future fertility potential of children. An epidemiological study, that consisted of an urological checkup, was performed among sch...

Vesicoureteral reflux, urinary infection and pyelonephritic scarring represent a well known triad in pediatric practice that may lead to severe scarring of kidneys, and development of so called reflux nephropathy. Apart from standard therapeutic options (conservative treatment and surgical therapy), endoscopic correction of refluxing vesicoureteral...

... If the testes fail to descend into the scrotum during postnatal development, they are exposed to elevated temperature (the core body temperature) and lose germ cells [3]. Male germ cells (especially haploid spermatids) are significantly reduced or completely lost in the cryptorchid testes [4]. The transition of gonocytes into type A dark spermatogonia (SSCs) in cryptorchid testes is impaired [5]. ...
... In an epidemiological study among boys in Serbia, the incidence of abnormal external genitalia was 27.8%, and the causative factors were unknown. [1][2][3][4][5][6][7][8][9][10][11][12] It is nearly impossible to limit the intake of phytoestrogens in our local context of Asia. To date, there has been no study to measure and correlate the level of phytoestrogens in male babies and the pathology of their external genitalia (micropenis, hypospadias, and penoscrotal transposition); descendent or undescended testes. ...
... If some of those developing ureters do not merge with metanephros, a 'blind-ending' ureter occurs. Other anomalies that usually occur with ureteral triplication are ureteral duplication on the opposite side, ureteric orifice ectopy and kidney dysplasia 11 . ...
... Antibiotic prophylaxis and management of bladder dysfunction have achieved excellent results in keeping low grade VUR. 2 However, it requires long-term antibiotic management and this is likely to induce resistance. 1 HA or without it for each type of the bacteria used (Table I, p>0.05 for each comparison). When used alone without any antibiotic discs, Dx/HA caused neither larger inhibition zones nor more bacterial proliferation around the pits compared with bacterial inoculation alone, for each of type of the bacteria. ...
... 14 Scrotal ultrasound is one of the main diagnostic tools for detection and monitoring of testicular abnormalities in boys. 15 Ultrasound is the modality of choice because it has high resolution for superficial structures including testes. 16 Ultrasound was used to determine whether a mass is solid or cystic, simple or complex and vascular or avascular. ...
