Ectopic (pelvic) kidney mimicking bulky lymph nodes at pelvic lymphadenectomy

Congenital pelvic kidney perfusion during infrarenal aortic aneurysm repair

Purpose: This case report describes a patient with a pelvic kidney associated with an aortoiliac aneurysm amenable to open repair. Methods: We chose the selective cold renal perfusion to preserve renal function. Results: Other techniques such as transient or permanent extra-anatomic bypass, extracorporeal circulation and proximal aortic double clamping are also described in this report. Conclusions: Choosing the renal perfusion technique depended on the anatomical evaluations of the kidney and the renal artery location during the preoperative period.

Safe Completion of Laparoscopic Anterior Resection in a Patient With a Solitary Pelvic Kidney: A Case Report

Pelvic kidney, an ectopic renal mass caused by developmental failure, is a rare condition. Here, we report a case of laparoscopic anterior resection in a patient with a solitary pelvic kidney. A 76-year-old man was diagnosed as having rectosigmoid colon cancer. Preoperative computed tomography revealed a left ectopic kidney in his pelvis. Computed tomographic angiography and retrograde pyelography were performed preoperatively to identify the renal vessels and the ureter. To keep the surgical plane intact for complete mesocolic excision, a complete laparoscopic anterior resection was safely performed without open conversion, and there was no injury to the pelvic kidney. The patient was discharged on postoperative day eight without any complication. No deterioration of renal function was observed after surgery. This report describes a case of laparoscopic anterior resection that was safely performed without conversion to open surgery in a patient with a pelvic ectopic kidney.

Ectopic Pelvic Kidney Mimicking Sacral Metastasis on Post-Therapy Iodine-131 Scan of a Thyroid Cancer Patient

A 25-year-old woman had total thyroidectomy and iodine-131 ablation therapy for papillary thyroid carcinoma. Whole body imaging on the 7^th day of therapeutic activity demonstrated radioiodine uptake in the remnant tissue and intense heterogeneous uptake at the sacral region prominently in the posterior image. Initial interpretation was suspicious for sacral metastasis. Technetium-99m-methylene diphosphonate bone scan demonstrated normal bone uptake and the absence of left kidney. On blood-pool phase of bone scan, the absence of left renal activity and an extra area of uptake in the sacral region suggestive of pelvic kidney were noticed. Magnetic resonance imaging scan confirmed the ectopic pelvic kidney overlying the sacrum.

Radical cystectomy and lymphadenectomy to two patients with pelvic kidney: surgical pitfalls and considerations

Our goal is to describe our experience in the difficulties encountered during radical cystectomy for muscle invasive bladder cancer in patients with contemporary pelvic kidney. Two patients with muscle invasive bladder cancer and contemporary pelvic kidney were subjected to radical cystectomy and extended lymphadenectomy with conversion to an ileal pouch. In both cases, lymphadenectomy was the first step after entering the true pelvis. In order to proceed to the cystoprostatectomy, careful dissection of the ectopic renal vessels and proper mobilization of the kidney were performed. In both cases, an ileal pouch was our choice. The pelvic kidney is the most common sight of renal ectopia. The etiology is the aborted ascent of the fetal kidney from its initial position in the pelvis. This is the first case series describing radical cystectomy for muscle invasive urothelial carcinoma of the bladder in patients with a pelvic kidney.

Fallopian tube carcinoma in a patient with a pelvic kidney: surgical management with the da Vinci robot

A patient with a known pelvic kidney and early fallopian tube carcinoma was managed with robotically assisted surgery. Associated conginital anomalies were noted and described. The final stage of the cancer was 1C, grade 3 and she is without evidence of recurrent cancer 2 years following completion of chemotherapy.

An adolescent affliction: nephrectomy and persistent severe pains due to misdiagnosed non-communicating "retroperitoneal" uterine horn

STUDY OBJECTIVE

To report the existence and management of retroperitoneal functioning uterine horn in a case with unicornuate uterus and to emphasis the significance of its misdiagnosis.

STUDY DESIGN

Case report.

SETTING

Assiut University, Woman's Health Hospital.

PARTICIPANTS

An adolescent female with progressive pains related to menstruation.

INTERVENTIONS

Extraperitoneal resection of the obstructed uterine horn.

MAIN OUTCOME MEASURE

Operative time, complications and postoperative pains.

RESULTS

A patient aged 11 years presented with severe lower abdominal pains, history of correction of ectopia vesicae in infancy, and recent history of nephrectomy for ipsilateral obstructed pelvic kidney. MRI and transrectal ultrasonography showed a pelvic mass with thick wall. Laparoscopy showed unicornuate uterus with only the left horn was being visualized. Hysteroscopy showed normal vagina and cervical canal communicating with normal left hemi-cavity. Extraperitoneal approach via extending the incision of previous nephrectomy was done under laparoscopic monitoring. Excision of the horn was done totally extraperitoneal without puncturing its covering parietal peritoneum within 65 min. No operative or postoperative complications were reported. Menstrual pains showed dramatic improvement after the procedure.

CONCLUSIONS

The present report is the first to describe the existence of a retroperitoneal functioning uterine horn with description of a successful extraperitoneal approach for its excision. Nephrectomy in the present case might be attributed to misdiagnosis of this problem.

Ectopic kidney with varied vasculature: demonstrated by CT angiography

An ectopic kidney was found incidentally in a 20-year-old male patient during the abdominopelvic CT angiography. It was situated on the right side at the abdominopelvic junction, partly in the abdomen at the level of the intervertebral disc between L3 and L4 superiorly and partly in the greater pelvis at the level of the promontorium and close to the inferior border of the sacroiliac joints. It was supplied by two arteries which were nearly in the same caliber, and each of which branched from the common iliac arteries both close to the aortic bifurcation. There were two renal veins. The larger one which was emerging from the lateral part of the ectopic kidney was draining into the inferior vena cava. The smaller one which was the only hilar vessel of the ectopic kidney was draining into the left common iliac vein. The orthotopic left kidney was also supplied by two arteries from the abdominal aorta. Ectopic kidneys pose a problem for any planned surgical intervention given their anomalous blood supply. Ectopic position and varied vasculature can predispose to iatrogenic trauma during interventional radiological and laparoscopic procedures, and emergency operations.

Incidental Findings During Routine Antepartum Obstetrical Sonography

The standard for performing an antepartum obstetrical sonogram primarily involves the examination of the fetus; however, both the American Institute of Ultrasound in Medicine (AIUM) and American College of Radiology (ACR) guidelines suggest the evaluation of maternal structures as well. The authors present 35 incidental findings that were discovered on routine antepartum obstetrical sonography. These include abdominal wall, gastrointestinal, reproductive, urinary, and vascular anomalies in the maternal structures. A review of the literature demonstrates that many of these findings have clinical significance, which highlights the wisdom of the AIUM and ACR guidelines, and it also stresses the importance of seeking and reporting them.

Combined laparoscopic and radical vaginal treatment of primary vaginal leiomyosarcoma in a patient with unicornuate uterus and pelvic kidney

We report a case of primary vaginal leiomyosarcoma occurring in a patient with a unicornuate uterus and pelvic kidney. The patient was treated with radical partial vaginectomy, unilateral groin dissection, total laparoscopic hysterectomy, and left pelvic laparoscopic lymphadenectomy, followed by adjuvant chemotherapy. Twenty-five months after her original procedure, the patient is alive and free of disease. The exact association between müllerian anomalies and primary malignancies of the genitourinary tract is unclear. It is nonetheless important to be aware of the close embryonic association between the genital and urinary tracts when evaluating such patients and choosing the appropriate surgical and therapeutic approach.

Radical cystectomy with extended lymphadenectomy in the presence of a pelvic kidney

The pelvic kidney represents the most common form of congenital renal ectopia. Because of its location, variable vasculature, and short ureteral length, the presence of a pelvic kidney in a patient undergoing radical cystectomy and pelvic lymphadenectomy creates unique technical challenges for the urologic surgeon. We describe a patient with a right pelvic kidney and invasive bladder cancer for whom radical cystectomy with extended pelvic iliac lymph node dissection and ileal conduit was performed.
