Maternal exposure to diethylene glycol monomethyl ether: a possible role in the etiology of retrocaval ureter.

Retrocaval ureter is a very rare condition. In light of the experimental studies, one of the etiologic factors seems to be maternal contact with diethylene glycol monomethyl ether or ethylene glycol monomethyl ether. A case of cardiovascular, skeletal, and retrocaval ureter anomalies caused by possible maternal contact while pregnant with these materials at her work in a textile factory is presented.

Treatment of retrocaval ureter.

Retrocaval ureter is a developmental anomaly of the course of the ureter in relation to the inferior vena cava. In spite of the fact the pathophysiological consequences of this anomaly are very serious, clinical manifestations are relatively poor. Experience with the management of this disorder in our 4 patients justifies the therapy we applied. It involves resection of a part of the ureter running behind the inferior vena cava, transposition of the ureter and subsequent end-to-end anastomosis of both parts of the ureter or of the ureter directly with the pelvis. The results verified at postoperative check-up examinations were very good, demonstrating the correctness of the tactics and procedure used.

Laparoscopic treatment of a retrocaval ureter.

A retrocaval ureter was treated laparoscopically with good success. The retrocaval segment of the ureter was easily separated and the ureter was reanastomosed using a laparoscopic suturing technique. Laparoscopic surgery is useful for the treatment of a retrocaval ureter with minimal postoperative pain and a short convalescence.

Laparoscopic pyelopyelostomy for retrocaval ureter without excision of the retrocaval segment: first report of 6 cases.

PURPOSE: We report our series of 6 cases of retrocaval ureter that were successfully treated with a laparoscopic approach. MATERIALS AND METHODS: Three men and 3 women with a mean age of 31 years (range 16 to 50) were referred to our department with a diagnosis of retrocaval ureter. One patient had a 12 mm renal pelvic calculus. A transperitoneal laparoscopic approach was used in all cases. The retrocaval segment along with some of the more proximal and distal segments of the ureter was readily mobilized. The distal part of the dilated renal pelvis was transected and the divided distal segment was repositioned to lie anterior to the inferior vena cava. The renal pelvic stone in 1 patient was readily removed at this point. Re-anastomosis was then performed over a Double-J stent placed intraoperatively using 2 rows of running 4-zero polyglactin sutures with intracorporeal knot tying. The stent was removed 4 weeks later. Excretory urography was performed 3 months after the laparoscopic procedure. RESULTS: Mean operative duration was 180 minutes (range 150 to 210). Patients were discharged home at a mean of 4 days (range 3 to 5). Followup excretory urogram 3 months after laparoscopic repair revealed a widely patent anastomosis with considerable improvement in hydronephrosis in all patients. CONCLUSIONS: To our knowledge this is the largest series of laparoscopic repair of retrocaval ureter reported to date. Laparoscopic pyelopyelostomy for retrocaval ureter without excision of the retrocaval segment is associated with an excellent outcome, minimal postoperative morbidity, short hospital stay and highly satisfactory cosmetic results.

Retrocaval ureter with hydronephrosis.

Retrocaval ureter is one of the rare congenital anomalies. We report a case of retrocaval ureter who presented with right lumbar pain, renal stone and hydronephrosis. The diagnosis was made on intravenous urography which showed typical "J" shape deformity in the proximal dilated ureter with moderate hydronephrosis. CT scan mapped out the course of ureter. The patient was operated and findings were confirmed. The ureter was transected near the pelvis, renal stone removed and a uretero-uretral anastomosis with anteriorisation of the ureter performed.

[Retrocaval ureter].

OBJECTIVE: To improve the diagnosis of retrocaval ureter. METHOD: 20 cases of retrocaval ureter with an average age of 33.4 years were reported. The diagnosis of this disease depends on urography and retrograde ureterography. Operation was the principal treatment. Ureter orthopedics and reduction were performed in 19 cases of type 1 (low loop) except one case of type II (high loop). After removing 3 - 4 cm retrocaval ureter with pathological changes, we anastomosed the ureter without tension and regained its normal anatomic position. RESULT: B-ultrasound and excretory urography showed no stenosis and improvement of hydronephrosis. CONCLUSION: Ureter orthopedics and reduction are ideal for the treatment of retrocaval ureter.

[Antecaval pyelopyelic anastomosis in retrocaval ureter].

Conservative surgery in retrocaval ureter consists of either ureteric resection with ureteroureteroanastomosis or antecaval ureteropyeloanastomosis without ureteric resection. Ureteroureteroanastomosis is often complicated by ureteric obstruction at the site of anastomosis. The authors offer in retrocaval ureter to establish antecaval pyelopyeloanastomosis which excludes anastomosis obstruction. The operative procedure is described. Good results were achieved in 3 children and 1 adult male treated.

Laparsocopic ureteroureterostomy for retrocaval ureter.

Two cases of retrocaval ureter are reported that were successfully treated by a laparoscopic approach. Case 1 was a 20-year-old woman who presented with symptoms of a right ureter stone. Case 2 was a 23-year-old woman who had suffered from recurrent right flank pain with gross hematuria. A transperitoneal approach was used for case 1, and a retroperitoneal approach was used in case 2. Both were successfully treated with laparoscopic ureteroureterostomy using an intracorporeal suture technique. Laparoscopic surgery should be the first choice for retrocaval ureter not only because of the minimal invasiveness but also because of the cosmetic advantage compared to conventional open surgery. Further technical and instrumental advances are essential for intracorporeal suturing.

Horseshoe kidney with a retrocaval ureter.

Horseshoe kidney and retrocaval ureter are two uncommon congenital anomalies of the genitourinary system that have rarely been reported to occur in the same patient. In each case previously reported, the isthmus of the horseshoe was positioned posterior to the inferior vena cava and anterior to the aorta. In no case was the diagnosis of both anomalies made preoperatively. We report a case of simultaneous horseshoe kidney and retrocaval ureter diagnosed by preoperative imaging studies and discuss the diagnostic evaluation and surgical management of this rare entity.

Retrocaval ureter: report of two cases and literature review.

Retrocaval ureter is a rare congenital anomaly in which the ureter passes behind, and is compressed by, the inferior vena cava. Its etiology is assumed to be abnormal embryologic development of the inferior vena cava as a result of atrophy failure of the right subcardinal vein in the lumbar portion. We report two cases of retrocaval ureter and review the relevant literature. One patient was a 7-year-old boy who presented with right flank pain. The other was a 40-year-old male who was found to have right hydronephrosis accidentally on abdominal sonography during a health examination. Both underwent retrograde pyelography which showed the typical S-shape of a retrocaval ureter. Abdominal computerized tomography and magnetic resonance imaging confirmed the diagnosis of retrocaval ureter. Ureteroureterostomies were performed. One patient showed focal squamous metaplasia of the ureter and the other had chronic inflammation and fibrosis. Follow-up studies showed improvement in hydronephrosis and renal function in both patients. We conclude that retrocaval ureter is a rare disorder and surgical correction is usually effective.

The surgical treatment of retrocaval ureter.

Ureteric obstruction resulting from retrocaval ureter may be due to either compression of the ureter by the vena cava or stenosis of the postcaval segment. If obstruction is due to stenosis, the commonly described operation of division and anastomosis through the proximal dilated ureter or pelvis, after repositioning of the ureter, is likely to fail, as is division of the vena cava itself. Excision of the postcaval segment with anastomosis of the spatulated ureter over a Silastic splint is therefore recommended. Three case histories of patients with retrocaval ureter treated surgically are presented and support this view.

[A case of retrocaval ureter in childhood].

We report a case of retrocaval ureter in a 14-year-old boy with the complaint of right flank pain. Intravenous pyelography and drip infusion pyelography showed right hydronephrosis and "inverted J" shaped ureter. A retrograde pyelography with venocavography revealed a typical retrocaval ureter, but abdominal CT scan did not show the "retrocaval segment". Ureterouretero-reanastomosis was performed and hydronephrosis was markedly improved. We analyzed 20 cases of retrocaval ureter in childhood.

Retrocaval ureter and associated abnormalities.

OBJECTIVE: To investigate the association of retrocaval ureter with other congenital abnormalities. METHODS AND PATIENTS: Two new cases of retrocaval ureter are discussed and a detailed electronic search of the literature was mainly focused on the concomitant abnormalities. The first of our patients had also a glandular hypospadias and a supernumerary lumbar vertebra, while the second one had syndactylia (fixed toes) in both feet. Results. The review of the literature revealed that 21% of the cases of retrocaval ureter present with concomitant abnormalities mainly from the cardiovascular system and the genitourinary tract. CONCLUSION: Diagnosis of retrocaval ureter should increase the awareness of the responsible physician on the possibility of concomitant malformations where treatment could prevent future symptoms.

Contemporary diagnosis of retrocaval ureter.

PURPOSE: We describe a noninvasive radiologic evaluation of a retrocaval ureter using currently available technology. MATERIALS AND METHODS: Three-dimensional volume-rendered CT and diuretic renography were performed for evaluation of a possible retrocaval ureter. RESULTS: The 3D CT scan definitively diagnosed the retrocaval ureter, while diuretic renography showed no evidence of clinically significant obstruction. No invasive procedures were required. CONCLUSION: A 3D volume-rendered CT scan in the excretory phase combined with diuretic renography is the radiologic evaluation of choice for patients with a suspected retrocaval ureter, as it is noninvasive yet highly accurate in its anatomic delineation.

Renal transplantation from a living related donor with a retrocaval ureter--a note of caution.

In our study we describe a renal transplant from a living related donor who was found to have a retrocaval ureter. The retrocaval ureter is a rare congenital anomaly resulting from a defect in the embryological development of the ureter and the inferior vena cava (IVC). The compression of the ureter between the IVC and the vertebrae can result in progressive hydronephrosis. The non-dilated segment of the ureter was used for the uretero-neocystostomy. The patient presented with ureteric obstruction in the immediate post-transplant period, and at surgical exploration the ureteroneocystostomy was revised using the dilated portion of the ureter. We recommend that when transplanting a kidney with a retrocaval ureter, caution should be exercised in using the non-dilated portion of the ureter, since either the blood supply may be compromised or the peristalsis may be interrupted.

Case report: retrocaval ureter: MR appearances.

We present a case of retrocaval ureter and its MR appearances. This is the first case in reported literature. The findings on i.v. urography are correlated with the MRI findings. So far CT has been the procedure of choice to confirm the diagnosis of retrocaval ureter. However, we believe MRI is likely to replace CT in the diagnosis of retrocaval ureter.
