The enlargement of the prostate is responsible for voiding dysfunction in men, and especially elderly men. The primary surgical treatment for symptomatic benign prostatic hypertrophy (BPH) was transurethral resection of the prostate (TURP).

However, current resection techniques are predominantly experience-based and judgment-based, with little evidence to support the most effective portion of the prostate to be respected. So, the investigators plan through the study to construct a flow diagram to evaluate the amount of tissue needed to be resected to improve voiding flow dynamics.

Benign prostatic hyperplasia (BPH) is an enlargement of the prostate gland that develops in men and is a common cause of voiding dysfunction in elderly patients. It is a major public health concern, causing high morbidity and substantial worsening of men's quality of life. (QOL)

Transurethral resection of the prostate (TURP) is the standard surgical therapy for obstructive prostatic hypertrophy. Various techniques have been suggested for the systematic removal of the adenomatous tissue, all based on the principle that the resection should be done stepwise as bleeding is the surgeon's major problem, leading to loss of visual field and disorientation, it is imperative that resection and hemostasis should both be completed in one area of the prostatic fossa before the next area is tackled. With the development of new techniques for prostate resection that decreases perioperative morbidity, larger sizes of the prostate are being resected, and a new category of patients is considered eligible for such an intervention with a large prostate size of more than 80 gm. However, current resection techniques are predominantly experience-based and judgment-based, with little evidence to support the most effective portion of the prostate to be resected to give us the best voiding outcome postoperative. So, the investigators plan through this study to construct a flow diagram to evaluate the amount of tissue needed to be resected to improve voiding flow dynamics.

Inclusion Criteria:

• Age: above 50 years old, undergoing an elective endo-urological procedure

Exclusion Criteria:

1. Neurogenic bladder
2. Previous prostate or urethral surgery
3. Associated urethral stricture

all male patients aged above 50 with enlarged prostate who will undergo endoscopic surgical intervention for any urological disease will be included in our study.

all male patients above the age of 50 years old with an enlarged prostate and undergoing any endourological procedure with perform cystoscopy during the standard endoscopic procedure.

Routine cystourethroscopy is a standard procedure in any endourological procedure, whatever the type of procedure.

With advanced imaging technology, it is possible through 3D scanning processes of analyzing photos and videos then digitally defining the depth, to create 3D models of the tissues and channels, from endoscopy videos.
