    If diversion necessary in patients of PU valve, it is for longer period of time. It may be for months or for couple of years.

    How SPC can hold so long?
    With this I would like to request you to read on PUV chapter...

    Defunctioning of the bladder by making a large opening is needed, therefore larger hole is better. 

    Managing a vesicostomy is easier than a SPC. 
    Decrease chances of UTI, as u avoid the foreign body

    Secondly by SPC you are increasing bladder spasms. So the purpose of diversion itself gets defeated.

    Commonest cause for failure of vesicostomy is siting it lower down. As such, the indications of vesicostomy are limited. But when indicated, it should be placed at the dome of the bladder. The key is to track it down from the urachus, instead of going from the anterior surface of the bladder.

    When it is not at the dome of the bladder, the posterior wall collapses and plugs the vesicostomy. Often it is structurally patent but child continues to void per-urethrally and the hydronephrosis worsens. So when indicated, siting it as high as possible, both in terms of skin incision and bladder incision and ensuring the opening is sufficient to admit the little finger, then it will serve the purpose.

    Primary valve fulguration is the method of choice in all PUV

    If VUR is seen in a PUV child who is not amenable for primary fulgration - then I would prefer unilateral loop ureterostomy on thr refluxing side over a vesicostomy. This decompresses both systems as the bladder fills and refluxes. 

    Vesicostomy often makes already conracted bladder further smaller in a PUV kid. Any tube (SPC/nephrostomy does nt stay for long in babies- max 7 days if lucky)
