[Histomorphometric findings in the residual prostate and prostatic hollow after retropubic surgery for BPH: (I) baseline data obtained from the last 70 consecutive cases].

Objectives: To present the data obtained from surgical specimens and biopsies of residual prostate and prostatic capsule, which in addition to the information provided by imaging tests give us the baseline situation of the prostatic surgical bed and residual prostate after transcervical hemostatic adenomectomy with capsule plasty. All this is the first step for the long-term study of its evolution and possible implications in the genesis of new obstructive or neoplastic pathology.

Methods: 70 consecutive cases of transcervical hemostatic adenomectomy with the variation of capsule plasty, recently developed, after a previous experience of 1033 retropubic surgeries. We analyze the histologic findings in surgical specimens, biopsies of residual gland and prostate capsule, and confirmed the immediate changes surgery causes, measuring the volumes of residual prostate by ultrasound. As the base for comparisons we analyzed residual prostates from prostatectomies or radical cystoprostatectomy specimens in "young" patients.

Results/conclusions: We obtained objective data about predominant and associated histological lesions found in adenomectomy specimens. In the same way, the same data were obtained from biopsies of peripheral residual prostate together with the volume of such zone, which should establish, if our hypothesis is right, the mid-long-term prognostic criteria for the approach to the so-called post operative reexpansion of the prostatic hollow and the possible establishment of new obstructive pathology.
