Abstract:
Objective To study the urodynamic characters of pelvic lipomatosis(PL) and its clinic significance.Methods From Sep.2013 to Feb.2016,7 patients,including 6 males and one female,were diagnosed as PL by image examinations and related lower urinary tract syndrome.Their mean age was 46 years,ranged from 30 to 52 years.All the patients(study group) have normal renal function.However,4 patients were noticed bilateral hydronephrosis.Other patients with similar LUTS but were confirmed as normal by image and urodynamic examinations were concluded in control group,which was paired designed to match the study group in visiting time,gender,age,and number of patients.The uroflowmetry and pressure/flow cystometry were performed in all patients.The urodynamic data of two groups including maximum flow rate (Qmax),time to maximum flow,post-voiding residual (PVR),first sensation capacity,first desire to void capacity,cystometric capacity,intravesical pressure at terminal of filling phase,compliance,detrusor pressure at maximum flow,detrusor opening pressure,bladder outlet obstruction index (BOOI) and bladder contractility index (BCI),were retrospectively analyized.Results There were no significant different between study aud control groups respect to Qmax [(18.71 ± 10.31) ml/min vs.(13.29 ± 6.55) ml/min],time to maximum flow [(6.71 ±2.50)s vs.(7.43±2.76)s],PVR [(28.14±27.81)ml vs.(3.14± 3.48) ml],first sensation capacity[(138.86 ± 77.01) ml vs.(142.29 ± 89.84) ml],first desire to void capacity [(203.71 ± 131.09) ml vs.(216.57 ± 72.20) ml],cystometric capacity [(271.0 ± 151.95) ml vs.(323.29± 92.87)ml],i ntravesical pressure at terminal of filling phase [(30.29 ± 16.45)cmH2O vs.(18.71 ± 9.57) cmH2 O],and compliance [(90.53 ± 126.46) cmH2O/ml vs.(129.57 ± 136.25) cmH2O/ml].The study group was significant higher than control group in terms of pressure at maximum flow [(69.57 ±25.06) cmH2O vs.(33.14 ± 11.63) cmH2O,P =0.004],opening pressure [(42.57 ± 22.16)cmH2O vs.(18.00±13.18) cmH2O,P=0.027],BOOI [(34.00±15.92)vs.(16.50±5.96),P=0.030] and BCI [(133.17 ± 27.37) vs.(87.67 ± 20.16),P =0.008],respectively.Moreover,the BCI of PL patients with hydronephrosis were significant higher compare with PL patients without hydronephrosis [(155.67 ±14.98) vs.(110.67 ± 1 1.37),P =0.014].Conclusions The urodynamic characters of PL were increased pressure at maximum flow and opening pressure,which implied obstruction.
