“…The urethral meatus is the narrowest part of the urethra and can be regarded as the ‘size’ of the urethra. The ‘normal’ minimum size of the urethral meatus in American male newborns was 7 F [23,24], while Snodgrass clearly quoted a minimum size of 10 F [18]. The calibre of the 17 TIP neourethrae was larger than the suggested normal minimum and 13 were within the ‘normal’ size cited by Snodgrass.…”

Objective To review our experience of using the tubularized incised plate (TIP) urethroplasty (useful in the treatment of distal hypospadias) to treat proximal hypospadias. Materials and methods From March 1997 to March 2000 primary repairs were carried out on 40 boys (mean age 4.5 years) with proximal hypospadias. After degloving the penile skin the meatus was at the mid-shaft in 10 boys, at the proximal penile shaft in 11, at the penoscrotal junction in 16, at the scrotum in two and at the perineum in one. The 21 patients with a mid or proximal shaft meatus were categorized as having mid-shaft and the other 19 as having posterior hypospadias. Tunica albuginea plication (TAP) was used to correct residual ventral curvature. The method of urethroplasty was adapted from that described by Snodgrass. The key step of the TIP repair is a midline incision of the urethral plate; a subcutaneous tissue¯ap dissected from the inner prepuce is used to cover the neourethra. An 8 or 10 F nasogastric tube is used as a urethral stent and removed 7 or 8 days after surgery. Follow-up endoscopy and urethral sounding were carried out in 17 of the patients aged <6 years; the mean followup was 12.5 months.Results TAP was used to correct penile curvature in nine (23%) of the patients. Excluding stenosis, the TIP repair was successful in 20 (90%) of those with midshaft and in 16 of the 19 with posterior hypospadias; for all complications the respective rates were 19 of 22 and 15 of 19. The overall success rate was 88% for all 40 patients with proximal hypospadias; a urethrocutaneous ®stula occurred in two of those with mid-shaft and three of those with posterior hypospadias. Urethral meatal stenosis occurred in four (12%) of the patients (two in each group); two were associated with a ®stula and the other two had only mild meatal stenosis. The overall complication rate was 17.5% (three and four in the mid and the posterior hypospadias groups, respectively). The meatal stenosis was managed by simple dilatation in three and meatoplasty in one patient. Endoscopically, the mucosa of neourethra was pink and smooth in all 17 patients assessed. The calibre of all 17 neourethra was o 8 F and in 13 was o 10 F. Conclusion TIP repair is a reliable method for treating both mid-shaft and posterior hypospadias.

“…It is important to know that a newborn male urethral meatus is approximately 7Fr. [3] Meatal caliber increases in size with age such that by age three, 85% of the males would have a urethral meatus caliber of 10Fr. [4] In newborn females up to one month of age, a 12Fr catheter can easily pass due to the influence of the mother′s estrogens.…”

Surgical management of urinary stones in children remains challenging due to the smaller caliber of the urinary tract. Specific instruments have been designed to overcome some of the issues related to pediatric stone management. Endoscopic and percutaneous modalities for stone management have been shown to be as safe and effective in providing stone clearance in children as in adults. Technologies that have been shown to be safe in adults are being miniaturized for use in children. The current literature regarding pediatric urolithiasis was reviewed in an effort to identify trends in operative management. Additionally, techniques used successfully at our institution are described. Although not an exhaustive review of all available modalities and instruments, this review will provide an overview of the current techniques for the management of pediatric urolithiasis.

Background: Circumcision is the most common surgical procedure performed in boys through out the world. Meatal stenosis is one of its late complications. Objective: The aim of the present study is to see the effectiveness of use of lubricants vaseline-petrelium jelly) during arumcision meatal stenosis. Methodology: A randomized control trial was performed, in which two groups of boys younger than two years old underwent circumcision according to dissection (sleeve) method. The parents in the study groups were strictly instructed to use petroleum jelly on the meatus and circumcision site at every morning or after each diaper change where necessary for three months. On the other hand parents in the control group were instructed not to use any lubricants or topical medication on the same site. The boys were followed up regularly and evaluated for meatal stenosis, bleeding and infection. Results: A total of 120 boys were recruited & in each group comprised of 60 boys. None of the boys in the study group develop meatal stenosis , but 6(10%) in the control group develop meatal stenosis (p< 0.05 ). Infection of the circumcision site was seen in 1 (0.6%) and 3 (5%) children in the lubricant and control groups, respectively (p<0.05) and bleeding was seen in 3 (5.0%) and 6(10.0%) respectively. Conclusion: Based on the findings of this study, it seems logical to use a lubricant jelly for prevention of post circumcision meatal stenosis and other complications.
