Introduction: Intravesical prostatic protrusion (IPP), a unique anatomical configuration has recently become a very significant component in the evaluation of BPH patients. Hence the present study aimed to evaluate the outcome of initial trial without catheter in Benign prostatic hyperplasia patients with IPP of different grades presented with acute urinary retention. Materials & methods: The retrospective study conducted at Urology unit, Department of General Surgery, Agartala Government Medical College, Agartala from September 2018 to January 2022. Patient fulfilling the inclusion criteria were included in the study. Data sheet was completed where the patient’s demographics, IPSS, PSA, total prostate volume, IPP and its grade, peak flow rate of voided patients, PVRU was recorded and analyzed. Results: Mean patient age was 69.76±9.54 years (range 52 to 87) in group A, 67.80±7.70 years (range 54-82) in group B and 66.23±8.84 years (range 51-81) in group C. Mean value of IPP was greater in group C with statistically significant result with p value <0.01 comparing group A and C. Correlation between IPP with other pre-treatment parameters show significant results with TPV, TZV, TZI, QoL, PUFR & PVRU. Conclusion- IPP is a helpful indicator for determining whether a voiding trial after ARU was successful. A trial without a catheter may be advantageous for BPH patients with grade 1 IPP. Patients with grade III IPP, on the other hand, are less likely to do so and would need a more thorough surgical intervention.
