目的:确定男性射精管开口的具体解剖部位,为临床诊疗如精囊镜检查、射精管梗阻的治疗等提供直观依据。方法:对21例(其中血尿12例、血精2例、腺性膀胱炎6例、直肠癌根治手术后不射精1例)年龄在26~47岁的患者做膀胱镜检查时,在知情同意的情况下膀胱镜尿道直视下行前列腺以及尽可能地接近精囊腺的按摩,观察按摩后排出液排出位置并行按摩后排出液的显微镜检查,发现精子的视为含有射精管排出液。结果:所有21例患者腔镜直视下前列腺按摩液和精液排出开口的具体解剖部位都在精阜上前列腺小囊开口侧方、前侧下方以及精阜的前侧方,13例患者在按摩后排出液中检查出大量精子。前列腺小囊开口没有看到任何液体(包括精液)的排出。结论:男性射精管开口位于精阜两侧、紧邻前列腺小囊开口,而非精阜上的前列腺小囊开口内。
Objective: To determine the specific anatomical site of male ejaculatory duct opening, providing an intuitive basis for clinical diagnosis and treatment such as seminal vesicle examination and ejaculatory duct obstruction. Methods: 21 cases (including 12 cases of hematuria, 2 cases of hematuria, 6 cases of cystitis glandularis, 1 case of ejaculation after radical operation of rectal cancer) were under cystoscopy in patients aged 26-47 years, Cystoscopy urinary tract straight down the prostate and as close as possible to the seminal vesicle massage, observe the discharge position after massage massage parallel discharge liquid microscopy and found that sperm is considered to contain ejaculatory duct fluid. Results: The specific anatomic sites of the prostate massage fluid and the semen discharge orifice in all 21 patients undergoing endoscopic surgery were both on the side of the open seminal vesicle, on the front side, and on the front side of the seminal vesicle on the front of the seminal vesicle. In the 13 patients, After the discharge of liquid to check a large number of sperm. Prostate capsule opening did not see any liquid (including semen) discharge. CONCLUSIONS: The male ejaculatory duct openings are located on both sides of the fine frenulum, close to the opening of the prostate sac, rather than the opening of the prostate sac of the fine corpse.
