ABSTRACT-A case of seminal vesicle cyst and ipsilateral renal agenesis is presented, the literature summarized, the embryology reviewed, and the diferential diagnosis discussed. Our reasons for surgical therapy are stated.
The differential diagnosis of a paraprostatic mass is always challenging. It involves a detailed knowledge of the embryology of the genitourinary tract. A patient with such a mass is described, the embryology of the area presented, and the world literature reviewed. Case Report A forty-one-year-old farmer, in excellent health, noted the urge to void at 9:00 A.M. but was unable to urinate. At noon, he was still unable to void. At 4:00 P.M. he was in a great deal of distress and began passing small amounts of urine incontinently. At 6:00 P.M. he spontaneously passed thick bloody urine per urethra. There were no clots; he denied any pain or burning. A sample of the fluid was collected, and he visited his doctor who confirmed the presence of blood and placed him on sulfisoxazole (Gantrisin) for ten days. His urine became clear over the next three voidings; all of which were initiated without difficulty. Ten days later at a return visit he was referred .to a urologist. He had undergone appendectomy twenty years before for acute appendicitis. He denied any history of urinary tract disease or symptoms preceding the episode of hematuria.

(37°C.) blood pressure 130190 mm. Hg. The only positive physical findings were a healed appendectomy scar in the right lower quadrant and a large paraprostatic cystic mass on the right, slightly above the prostate, nonmovable and nontender. The penis and urethral meatus were normal, and the scrotal examination revealed normal testis, epididymis, and vas bilaterally. The prostate felt normal in size and consistency. Laboratory data were as follows: blood count, 4,000 per cubic millimeter; hemoglobin, 15.5 Gm. per 100 ml.; hematocrit, 45; urinalysis revealed no white or red blood cells; urine culture showed no growth. An intravenous pyelogram revealed a hypertrophied but normal left kidney and ureter but no evidence of a kidney on the right. On the excretory cystographic phase no mass was noted. The bladder outline appeared normal (Fig. 1A). Cystoscopy revealed the absence of the right hemitrigone, a smooth bladder wall with no evidence of distal obstruction, and a large extrinsic mass on the right side pushing on the bladder. An aortogram was performed. No renal artery was noted on the right, and the views of the pelvis on the films did not show any abnormal blood vessels (Fig. 1B).

At exploration a midline transperitoneal incision was made, the posterior peritoneum was opened, and the mass was dissected free from the right posterolateral wall of the bladder. The vas was noted entering the mass. It could not be separated from it and was interupted and ligated. The other end of the vas entered the mass. During the procedure, the mass was entered, and about 30 cc. of blood-tinged fluid was removed. There was no odor. Smear did not reveal any sperm; the culture was negative. The mass was excised, and a culture for tuberculosis was negative. The peritoneum was closed over the raw area and the wound closed. Postoperatively, he suffered with urinary retention, and in an attempt to catheterize him, his urethra was perforated. He underwent immediate laparotomy, suprapubic cystotomy, and insertion of paravesical drains. His course from then on was benign. The pathologic report revealed the presence of a cyst, lined with low cuboidal epithelium consistent with seminal vesicle cyst (Fig. 2). At follow-up three months later, the patient was asymptomatic and voiding satisfactorily. Embryology As the embryo ages, the mesonephros (the second of the three organs in the developing urinary system in man) atrophies and disappears, but its tubules and ducts persist and form parts of the adult genital system in both sexes.

Cyst of the seminal vesicle is itself a rare entity. Until 1971 only 20 cases had been accepted according to Block.2 Smith” reported the first case, a mass containing 5,000 cc. of fluid which he treated by transrectal drainage. Englisch* described four genital cysts: (1) wolffian duct cyst, along the vas deferens; (2) miillerian duct cyst, midline; (3) sinus pocularis cyst, atresia of the utricular orifice; and (4) Zinner5 seminal vesicle cyst, anterolateral. described the first seminal vesicle cyst associated with ipsilateral renal agenesis and discussed the possible cause of the combined picture.

view of specimen;
The mesonephric duct turns abruptly just before it enters the cloaca, and the ureteric bud arises just proximal to the turn. The seminal vesicle outpouches at thirteen weeks, in close proximity to the ureteric bud which had developed previously at four weeks. Any malformation of the bud could easily also affect the seminal vesicle outpouching, and then combined anomalies result. Zinner4 believed that congenital atresia of the ejaculatory duct was the cause of the retention cyst of the seminal vesicle. Deming6 in discussing the seminal vesicle cyst with normal ipsilateral renal development stated that it was unilateral, single, contained old blood probably secondary to distention and consequent bleeding

into the cyst and believed that it was caused by either a congenital or acquired obstructive process in the ejaculatory duct. Heetdeers and Delambre7 believed that there was a discontinuity between the seminal vesicle and the ejaculatory duct either acquired or congenital. Patton* believed that the mesonephric duct failed to acquire a normal opening into the cloaca, and after birth secretion occurred and a mechanical effect the same as obstruction was produced, a cystic mass resulted. Hartg*10 considered that all these cysts resulted from an angulation of the mesonephric duct at its cloaca1 end with faulty development of the ureteral diverticulum and its neighbor, the seminal vesicle. Tritsch” established a correlation between recurrent prostatism and seminal vesicle cyst formation caused, he believed, by recurrent ejaculatory duct obstruction and consequent back pressure. Rieser and Griffin12 described
Reviewing the 7 cases described of seminal vesicle cyst and ipsilateral renal agenesis, 2 patients were asymptomatic and 1 had an external penile problem (Table III). The presence, at cystoscopy, of a hemitrigone on the same side does not rule out the possibility of renal agenesis. Campbell, in 1951, describing 248 cases of renal agenesis, noted that 24 had a hemitrigone and an atretic ureter on the ipsilateral side. Our patient, the oldest in the series, did not have any cystic involvement of the ipsilateral epididymis as described by Rieser and Griffin,‘2 and he was the first patient with documented hematuria. In evaluating the patient, we believe that angiography is superior to needle aspiration especially in the light of the recent report by Smith, Webb, and Price13 of carcinoma in the seminal vesicle cyst. We also consider that surgical exploration with excision is mandatory for the same reason.
four genital cysts: (1) mtillerian duct cyst, (2) cyst of the seminal vesicle, (3) retention cyst of the prostate, and (4) diverticulum of ampulla/ ejaculatory duct. The differential diagnosis included the position of the mass, the presence or absence of sperm in it, and a normal or enlarged ipsilateral epididymis:
