The venous drainage of the urinary bladder was studied in 20 pelvic halves (14 males and 6 females). Vesical and prostatic plexuses draining the bladder (vesical only in females) were found in 16 cases; they supplied blood to the internal iliac vein--usually by two to five veins--the most common number being three. One vein always drained the prostatic plexus. The vesical and prostatic plexuses were absent in 4 male cases, where the vesical veins issuing from the bladder wall drained directly the internal iliac vein. Their number in such cases was minimal: between one and two only, on each side. The union of a vesical vein issuing from any of the two mentioned plexuses (when found) with the obturator, prostatic or vaginal vein was common. A shunt from a common trunk of united obturator and vesical veins to the external iliac vein was noticed in some cases. Occasionally, an inferior vesical vein ending in the obturator vein accompanied an inferior vesical artery initiating from the obturator artery.
对20个半侧骨盆（14例男性和6例女性）的膀胱静脉引流进行了研究。在16例中发现了引流膀胱的膀胱丛和前列腺丛（女性仅为膀胱丛）；它们通常通过两到五条静脉为髂内静脉供血，最常见的数量是三条。总有一条静脉引流前列腺丛。4例男性病例中不存在膀胱丛和前列腺丛，膀胱壁发出的膀胱静脉直接引流至髂内静脉。在这种情况下，它们的数量很少：每侧仅一到两条。从上述任何一个丛（如果存在）发出的膀胱静脉与闭孔静脉、前列腺静脉或阴道静脉汇合很常见。在某些情况下，注意到有一条从联合的闭孔静脉和膀胱静脉的共同主干到髂外静脉的分流。偶尔，一条汇入闭孔静脉的膀胱下静脉会伴随一条起源于闭孔动脉的膀胱下动脉。
