OBJECTIVETo explore the correlation between the Traditional Chinese Medicine (TCM) syndrome differentiation and urodynamic parameters in benign prostate hyperplasia (BPH).

METHODSUrodynamic examination was conducted for 152 BPH patients, who were divided by TCM syndrome differentiation into seven types, namely, kidney-yin deficiency, kidney-yang deficiency, aqueduct stagnancy, spleen-qi deficiency, lung-heat and qi stagnancy, wetness-heat down-flow and phlegm-wetness stagnancy.

RESULTSOf the total number of the BPH cases, 71 (46.71%) were differentiated as the type of kidney-yang deficiency, 40 (26.31%) as aqueduct stagnancy, and 14 (9.21%) as kidney-yin deficiency. Fifty-eight cases of Grade III-IV bladder outflow obstruction fell into the type of kidney-yang deficiency, and another 38 cases of the same grade along with 26 cases of Grade V-VI came under the type of aqueduct stagnancy. Of the 12 patients with very weak contractility of detrusor urine, 4 (33.33%) were attributed to the type of kidney-yang deficiency and 7 (58.33%) the type of aqueduct stagnancy. Among the 48 with weak contractility of detrusor urine, 27 (56.25%) fell under the type of kidney-yang deficiency and 17 (35.42%) the type of aqueduct stagnancy.

CONCLUSIONThe TCM syndrome differentiation of BPH is correlated with bladder outflow obstruction and detrusor urine contractility, which has provided corresponding evidence for the quantization and objectification of the TCM syndrome differentiation of BPH.
