    Dear All,

    We must compliment Udayshankar for introducing new concepts in into our understanding of PUV. We thought we knew most of PUV but recent studies are proving our lack of understanding. Are we willing to accept some of these new concepts emanating, the answer is both yes and no. Take for Example the concept of Single leaflet instead of two leaflets as commonly believed Introduced by Paddy Dewan and confirmed by Lawrence Baskin. Do we except this concept and the answer is a big NO and we go on with the concepts as laid down by Young in 1919. Similarly many issues with PUV are not fully appreciated even now though considerable work has emanated in these areas. One such addition is provided by Udayshankar for us. In his article he cites a work of Nobuyuki Hinata and Gen Murakami (2014) which is worth reading and understanding.

    We think that Aggressive treatment of PUV will benefit the renal functional outcomes and benefit these children. Hideo Nakai* et al (2017) in an article ask whether such aggressive treatments can become an aetiology for VUR and Urge incontinence in children. I am providing the link from which you can gain more information.

    There are many abortive cases of PUV that may not be recognized early in life. Mehmet Ali Özen et al (2019) concluded by stating that ‘Late-presented PUVs may be missed on VCUG. Whether a PUV might be present is crucial in boys with a history of recurrent urinary infection, persistent reflux, and repetitive daytime incontinence. Based on our results, we conclude that cystoscopic examination should be preferred for those cases to diagnose PUVs regardless of VCUG results’. Similarly Bernard Haid* et al  (2020) in a paper published Online on March 30th queried whether there is a need for Endoscopic Evaluation in Symptomatic Boys with an unsuspicious Urethra on VCUG. They brought out the Secondary Radiological Signs of PUV. They concluded as Mehmet Ali Özen et al that ‘Unsuspicious findings of the urethra on VCUG cannot exclude a relevant PUV and implicate a risk of disregarding abortive forms. The presence of secondary radiologic signs of infravesical obstruction on a VCUG despite an unsuspicious posterior urethra in boys with recurrent UTI’s as well as refractory symptoms of bladder overactivity or suggestive signs on sonography must be further clarified endoscopically’.

    From the recent studies pertaining to PUV, it is clear that we will have to understand much more into various aspects of PUV and not be satisfied only issues concerning Renal outcomes, however important they maybe.

    With warm Regards,

    Dear All,

    A while ago I had prepared a write up on ‘Development of PUV’ and I am sending it to you for whatever benefits it may have for you.

    I hope all will go through the write up and give your valued comments on the write up.

         The article only postulate rhabdomuscle spasm as a cause for high pressures in bladder. They have not presented any concrete evidence to support this theory. 

         There is ample evidence in the literature that high pressures can develop in bladders years after a successfully treating PUV. Here there is no evidence of ext sphincter spasm. Here high bladder pressure is the result of dormant primary event in detrusor.
