“…embryo stage, when the kidneys are in the true pelvis. 6 The horseshoe kidney lies at a position (L3 to L5) lower than normal since the ascent of its isthmus is prevented by the inferior mesenteric artery root. Medial rotation of the renal pelvis is also prevented and the ureters enter the pelves higher up than in normal kidneys, arising from the inner border of the upper part of each kidney and passing over the anterior surface of the isthmus.…”

“…In lowlying asymmetrical horseshoe kidneys the confluent renal vein may drain into the left common iliac vein. 6,10 Accurate visualization of the abnormal renal vasculature is extremely important for meticulous preoperative planning and it serves as a roadmap for the safe performance of surgery. It can be achieved by helical CT with 3-D digital reconstruction, magnetic resonance angiography or 3-D power Doppler ultrasound.…”

Does Retroperitoneal Lymphadenectomy For Testicular Germ Cell Tumor Require a Different Approach in the Presence of Horseshoe Kidney?

et al. 2003

Purpose: We report our management of stage II testicular nonseminomatous germ cell tumor in 2 patients with horseshoe kidney and discuss the technical challenges posed by this renal fusion anomaly. The embryology and clinical anatomy of horseshoe kidney are discussed with particular reference to the anomalous vascular pattern and routes of testicular lymphatic drainage in this setting. Modifications and innovations of the standard technique of retroperitoneal lymphadenectomy in the presence of horseshoe kidney are discussed in light of our experience with these patients at 2 major tertiary care cancer centers. The significance of contemporary advanced noninvasive radiological techniques, such as helical computerized tomographic angiography with digital 3-dimensional reconstruction and magnetic resonance angiography, in the surgical planning and safe performance of surgery is emphasized.Materials and Methods: Two young male patients treated at 2 major American teaching hospitals who had coexistent stage II testicular nonseminomatous germ cell tumor and horseshoe kidney underwent salvage retroperitoneal lymph node dissection.Results: There was no evidence of recurrence in these 2 patients 12 and 15 months after surgery, respectively.Conclusions: Horseshoe kidney poses special technical problems during retroperitoneal lymphadenectomy for testicular tumors due to anomalous renal and intra-abdominal vascular patterns. Helical computerized tomography angiography is useful for meticulous surgical planning and the safe performance of surgery in this setting.

“…The ureter of the lower pole generally ends in the bladder but has a short intravesical tunnel, often leading to vesico-ureteral refl ux (VUR). While the lower unit is usually preserved anatomically and functionally, that of the upper moiety is frequently dilated or dysplastic (2).…”

Laparoscopic ureteropyeloanastomosis in the treatment of duplex system

et al. 2012

View full text Add to dashboard Cite

Purpose: Duplex system is one of the most common anomalies of upper urinary tract. Anatomical and clinical presentation determine its treatment. Usually, the upper moiety has a poor function and requires resection, but when it is not signifi cantly impaired, preservation is recommended. Laparoscopic reconstruction with upper pole preservation is presented as an alternative treatment. Materials and Methods: Four female patients with duplex system, one presenting with recurrent urinary tract infection and the others with urinary incontinence associated to infrasphincteric ectopic ureter, were treated. Surgical procedure envolved a laparoscopic ureteropyeloanastomosis of the upper pole ureter to the pelvis of the lower moiety, with prior insertion of a double J stent. Results: Surgical time varied from 120 to 150 minutes, with minimal blood loss in all cases. Follow-up varied from 15 to 30 months, with resolution of the clinical symptoms and preservation of the upper moiety function. Conclusion: Laparoscopic ureteropyeloanatomosis is a feasible and safe minimally invasive option in the treatment of duplex system. Laparoscopic ureteropyeloanastomosis in the treatment
