Abstract
Objective

Evaluate the effect of dutasteride in perioperative bleeding during Transurethral Resection of Prostate (TURP).

Materials and Methods

Forty consecutive patients with criteria for TURP were included. Finasteride/dutasteride use, renal impairment, prostate <30cc, age <50 were excluded. Patients were divided in 2 groups. Group 1: 24 consecutive patients treated with dutasteride 0.5mg/day/30-days prior TURP. Group 2: 16 without treatment. Prostatic volume, difference in hemoglobin pre/post TURP, duration and amount of resected tissue were recorded. Surgeon was blinded. Statistical analysis: Multiple linear regression, Mann-Whitney and student t-tests were used.

Results

In group 1, 33%(8) improved their lower urinary tract symptoms and skipped TURP. Mean Hemoglobin loss difference between groups was 0.11gr/dl (CI 95% −0.55; 0.77, p=0.88). There was no statistical difference among variables. No positive or negative predictive values in the linear regression model.

Conclusion

Dutasteride did not significantly impact the studied variables in these non randomized and small sample size settings.

Resumen
Objetivo

Evaluar el efecto del dutasteride en el sangrado perioperatorio durante la resección transuretral de la próstata (RTU-P).

Material y métodos

Un total de 40 pacientes fueron incluidos. Los pacientes recibiendo finasteride o dutasteride, creatinina >2mg/ml, con volumen prostático <30cc, edad < 50 fueron excluidos. Los pacientes fueron divididos en 2 grupos. En el grupo 1: 24 pacientes consecutivos que aceptaron recibir dutasteride 0,5mg/día durante 30 días previo a la RTU-P. En el grupo 2, 16 pacientes consecutivos sin tratamiento adicional (control). Los valores de hemoglobina previos e inmediatamente posteriores a la RTU-P y el peso del tejido resecado en gramos fueron recolectados. El cirujano estuvo cegado. El análisis estadístico utilizado fue la prueba t de student, la prueba no paramétrica de Mann-Whitney y una regresión linear múltiple.

Resultados

En el grupo 1, 33% (8) mejoró su sintomatología obstructiva urinaria baja y no evitaron la RTU-P. La media de la diferencia, entre los grupos 1 y 2, de la Hb en los valores antes y después de la RTU-P fue 0,11 g/dl (IC 95% −0,55; 0,77, valor de la p 0,88). No hubo diferencias estadísticamente significativas en las variables del modelo de regresión linear múltiple.

Conclusiones

El dutasteride no tuvo un impacto significativo en las variables estudiadas en este pequeño estudio no aleatorizado.
