Background: Transurethral resection of the prostate (TURP) is the best surgical and least problematic procedure for
symptomatic treatment of benign prostatic hyperplasia (BPH). It is important for nurse to educate the patient pre-
operative, to support the patient during the disease and its treatment. Therefore, Aim: the aim of this study is to assess
the effect of implementing preoperative nursing guidelines on postoperative outcomes among transurethral resection of
prostate surgery patients. Method: A quasi-experimental research design was used Setting: The study was carried out at
the prostate surgery unit in the Urology Center (UC) at Mansoura University. Study subjects: A purposive sample of
(100) patients undergoing TURP was randomly split into two groups with an equal size study group that received
nursing guidelines in addition to routine nursing care, and control group who received only routine hospital nursing care.
Tools: To gather the information and accomplish the study's goal, three tools were applied.: Tool I: Structured Interview
Questionnaire, Tool II: Patient Health Assessment Sheet. Tool III: Assessment of Patients' Outcomes. Results: The
present study showed significant improvement in the level of total knowledge, self-reported practices, and total post-
operative outcomes in the study than the control group post-implementation of nursing guidelines. Conclusion: the pre-
operative nursing guidelines have a favorable impact on the recovery after transurethral resection of the prostate in
patients. Recommendations: Developing educational guidelines to improve postoperative outcomes of patients
undergoing transurethral resection of the prostate and eliminate patient complications.
