[Histomorphometric findings in the residual prostate and prostatic hollow after retropubic surgery for BPH: (I) baseline data obtained from the last 70 consecutive cases]. / Hallazgos histomorfométricos de la próstata residual y celda prostática tras la cirugía retropúbica por H.B.P.: (I) datos basales obtenidos en los últimos 70 casos consecutivos.

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.

Hallazgos histomorfométricos de la próstata residual y celda prostática tras la cirugía retropubica por HBP: (I) Datos basales obtenidos en los últimos 70 casos consecutivos / Histomorphometric findings in the residual prostate and prostatic hollow after retropubic surgery for BPH: (I) Baseline data obtained fro the last 70 consecutive cases

Objetivo: Exponer los datos que obtenidos en el estudio patológico de las piezas operatorias, así como las biopsias de la próstata residual y cápsula prostática que junto a los que nos proporcionan los métodos por imagen nos ofrecen la situación “basal” en que, tras la adenomectomía transcervical hemostática con vesicocapsuloplastia, queda la celda y la prostata residual periférica. Todo ello como primer paso para el estudio a largo término de su evolución y su posible implicación en la génesis de una nueva patología obstructiva o neoplásica. Método: Lo constituyen las últimas 70 adenomectomías transcervicales (ATH) con la variante de vesicocapsuloplastia (VCP) aplicada recientemente y tras una experiencia anterior de 1.033 cirugías retropúbicas. Se analizan los hallazgos histológicos de las piezas operatorias, de las biopsias de glándula residual y de cápsula prostática y se constatan los cambios inmediatos que la cirugía ocasiona con medición de los volúmenes de próstata residual por ecografía. Como base comparativa se analizan próstatas residuales de piezas de prostatectomía o cistoprostatectomía radical en sujetos “jovenes”. Resultados/Conclusiones: Se obtienen datos objetivos sobre las lesiones histológicas dominantes y asociadas halladas en la pieza de adenomectomía. Igualmente sobre los mismos datos que ofrecen las biopsias de próstata residual periférica junto al volumen de dicha zona y que deberán, si nuestras suposiciones son correctas, establecer a medio- largo plazo criterios de aproximación pronóstica sobre la llamada reexpansión de la celda y el posible establecimiento de una neopatología obstructiva (AU)
