Retrocaval Ureter

Ureter Postcaval


Presentation

  • We describe the initial presentation, imaging, port placement, and operative technique including video presentation of a robot-assisted laparoscopic repair of a retrocaval ureter.[ncbi.nlm.nih.gov]
  • We present multimodality imaging of a meandering right pulmonary vein in a 29-year-old female patient.[ncbi.nlm.nih.gov]
  • Though it is a congenital anomaly, patients do not normally present with symptoms until the 3rd and 4th decades of life from a resulting hydronephrosis.[ncbi.nlm.nih.gov]
  • It usually presents with ureteral obstruction, and surgery is needed for symptomatic cases. We present a case of retrocaval ureter and a revision of the literature. A 9 year-old boy who had consulted for macroscopic hematuria.[ncbi.nlm.nih.gov]
  • Here, we present a case of a retrocaval ureter repaired with the single-incision multiport laparoendoscopic technique.[ncbi.nlm.nih.gov]
Lymphadenopathy
  • Retrocaval ureter can be associated with Turner’s syndrome Causes of Ureteral Deviation or Displacement Medial Displacement or Deviation Upper ureter Lower ureter Retrocaval ureter Lymphadenopathy Retroperitoneal fibrosis Iliac artery aneurysm Bladder[learningradiology.com]
  • Mild hydronephrosis in majority of this type Differential Diagnosis Causes of Ureteral Deviation or Displacement Medial Displacement or Deviation Upper ureter Lower ureter Retrocaval ureter Lymphadenopathy Retroperitoneal fibrosis Iliac artery aneurysm[learningradiology.com]
Ankle Edema
  • The patient was 7 months into her fifth pregnancy, which had been uneventful except for ankle edema. Approximately 18 hours before admission, the patient had a sudden onset of severe pain in the right flank and loin associated with nausea.[kundoc.com]
Intermittent Fever
  • CASE REPORT A 17-year-old female presented with intermittent right flank pain, dysuria, and intermittent fever for 2 months. Her physical examination was unremarkable except for a palpable, mildly tender right flank lump.[urotoday.com]
Right Flank Pain
  • We present the first two cases to be reported in Ghana; a 36-year-old male and a 40-year-old female both with right flank pains and associated right hydronephrosis.[ncbi.nlm.nih.gov]
  • Three patients presented with recurrent colicky right flank pain while one was asymptomatic. Two patients each had Type I and Type II retrocaval ureters, respectively.[ncbi.nlm.nih.gov]
  • 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.[ncbi.nlm.nih.gov]
  • A 60-year-old woman presented with complaints of intermittent right flank pain which had begun one year ago.[ncbi.nlm.nih.gov]
  • 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.[ncbi.nlm.nih.gov]
Pelvic Mass
  • AP resection) Pelvic lipomatosis Lateral Displacement or Deviation Upper ureter Lower ureter Lymphadenopathy Pelvic mass, e.g. uterine fibroids Aortic aneurysm Retroperitoneal hematoma Herman, T and McAlister, W: Radiologic Clinics of North America.[learningradiology.com]

Suggestibility
  • The intravenous urography (IVU) suggested the diagnosis of retrocaval right ureter, which is confirmed by magnetic resonance imaging (MR). Make us resection of the retrocaval segment and relocation of the ureter anterior to the inferior vena cava.[ncbi.nlm.nih.gov]
  • It is suggested that long term stagnation of urine is the cause for such a high incidence of malignant neoplasm involving the renal pelvis.[ncbi.nlm.nih.gov]
  • Radiological imaging demonstrated hydronephrosis, suggesting the presence of a retrocaval ureter. A LESS repair was planned. Retrograde pyelogram confirmed a classic appearance for retrocaval ureter. A ureteral stent was positioned.[ncbi.nlm.nih.gov]
  • Our results in 4 patients suggest that this minimally invasive approach is a feasible treatment of retrocaval ureter. Long-term follow-up of more cases is needed to confirm its benefits.[ncbi.nlm.nih.gov]
  • Operative repair is always suggested in cases of significant functional obstruction. Laparoscopic procedures have been employed as the minimally invasive therapeutic option for retrocaval ureter.[ncbi.nlm.nih.gov]
Impulsivity
  • The electrophysiological activity was normal with normal anterograde impulse transmission. Renal pelvic pressure and pressure increase during forced diuresis was within a normal range.[ncbi.nlm.nih.gov]
Ureteral Disorder
  • Ureteral Disorders Your kidneys make urine by filtering wastes and extra water from your blood. The urine travels from the kidneys to the bladder in two thin tubes called ureters. The ureters are about 8 to 10 inches long.[icdlist.com]

Workup

  • Haematological workup was normal. Ultrasonography showed hydronephrosis with antero-posterior diameter of 3.5cm associated with dilatation of upper ureter (dia-9.2 mm). Micturating cystourethrogram was done to rule out vesico ureteric reflux.[medcraveonline.com]
  • We present the workup on this patient as well as the management. We also present a literature review regarding this anomaly. Key words: Retrocaval ureter, circumcaval ureter. REFERENCIAS Rubinstein I, Cavalcanti AG, Canalini AF, Freitas MA.[new.medigraphic.com]
Pneumoperitoneum
  • The patient is placed in a modified flank position, pneumoperitoneum created and ports inserted. The colon is mobilized to expose the retroperitoneal structures: inferior vena cava, right gonadal vein, right ureter, and duodenum.[ncbi.nlm.nih.gov]
  • After pneumoperitoneum was created, a 2.5-cm incision was made in the umbilicus, and three conventional laparoscopic ports were inserted.[ncbi.nlm.nih.gov]
  • Pneumoperitoneum was produced by using a veress needle. 4 ports are then placed.[siiut.com]
  • Once pneumoperitoneum was created, a 10 mm port was placed in the semilunar line just above the umbilicus level. A 5 mm port was placed subcostally in midclavicular line and another 5 mm on the spinoumbilical line midway.[urologyannals.com]
Anisocytosis
  • Slight hypochromia; slight anisocytosis; and slight left shift. On the obstetrical service, after finding no urine at two catheterizations, the patient was given sedation, antispasmotics and intravenous fluids.[kundoc.com]
Creatinine Decreased
  • Then, the creatinine decreased gradually. On 9 November 2006, the pyelostomy was closed and left nephrectomy was performed.[journals.lww.com]

Treatment

  • Recently, the laparoscopic approach has become the gold standard for treatment, relegating open surgery as a second option.[ncbi.nlm.nih.gov]
  • CONCLUSIONS: Pure laparoscopic pyelopyelostomy seems technically feasible and reliable for RCU treatment. Our experience showed that laparoscopy should be the standard treatment option for such patients. Copyright (c) 2010 Elsevier Inc.[ncbi.nlm.nih.gov]
  • CONCLUSION: Our results have demonstrated that retroperitoneal LUUS was a safe and effective procedure, and an excellent minimally invasive treatment option for RCU.[ncbi.nlm.nih.gov]
  • CONCLUSIONS: We report our initial experience using LESS for the treatment of retrocaval ureter. Our results in 4 patients suggest that this minimally invasive approach is a feasible treatment of retrocaval ureter.[ncbi.nlm.nih.gov]
  • CONCLUSIONS: Our results indicate that retroperitoneal laparoscopic ureteroureterostomy is a safe and effective procedure, and an excellent minimally invasive treatment option for retrocaval ureter.[ncbi.nlm.nih.gov]

Etiology

  • 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.[ncbi.nlm.nih.gov]
  • 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.[ncbi.nlm.nih.gov]
