Majority of the patients are in Grade II IVPP (43%), whereas the incidence of Grade I and Grade II patients is almost the same.
Median lobe alone is presented as IVPP in 31% and lateral lobe alone is in 12%.
Pressure flow study is done only in 61 patients (out of 100), as the Urodynamic machine (Delphi's TM Laborie) is available only from mid-2013 in our department; 71% of grade I, 78% of grade II and 88% of grade III IVPP had significant obstruction (BOOI >40) demonstrated with pressure flow study (p<0.
IVPP along with Q-max and PVR is correlated for obstruction as demonstrated by PFS and analysed statistically using computer software packages SPSS (Statistical Package for Social Sciences) and Positive predictive value calculator 9.
There is no decrease in the measurement of IVPP in those patients with medical treatment, whereas TURP patients showed no demonstrable protrusion.
The increasing grades of IVPP are significantly directly correlated with IPSS score max and post void residual.
IVPP has a very good positive and negative predictive value and also a good accuracy rate in comparison with all other parameters in predicting the BOO.
The surgical intervention statistically proved to be superior to medical treatment in IVPP patients, especially most significant in Grade II and III IVPP patients.
Although, the body proportions of this Asian choristodere are still unknown, the total length would have been less than 1 m even if it was long-necked (by comparison with the largest specimens of the Lower Cretaceous Hyphalosaurus IVPP V11075).
