OBJECTIVES: Primary carcinoid tumor of the renal pelvis is a rare neoplasm with few cases reported in the literature. Here we present the clinical and histopathologic findings of a primary carcinoid tumor arising in the left renal pelvis of a horseshoe kidney in a 61-year-old female patient. MATERIALS AND METHODS: Pathologic features were evaluated with standard hematoxylin and eosin sections and immunohistochemical studies. A literature review was performed to place our case in context to previous reports...

We present a case of UPJO associated with an incompletely duplicated collecting system in a horseshoe kidney that was successfully treated by laparoscopic pyeloplasty with concomitant pyelolithotomy. A 53-year-old man had three urological anomalies and urolithiasis. We performed a pyeloplasty and pyelolithotomy using a fully intracorporeal technique. Clinical and radiographic evaluation confirmed complete resolution of the patient's condition. To our knowledge, there have been no reported cases of UPJO in an incompletely duplicated collecting system with a horseshoe kidney in the same patient...

To evaluate safety and efficacy of minipercutaneous nephrolithotomy (Mini-PNL) in management of stones in different types of renal anomalies. Patients with stones ≥2 cm or SWL-resistant stones in anomalous-kidneys treated by Mini-PNL between March 2010 and September 2012 were included prospectively. Mini-PNL was done under regional anesthesia in prone position with fluoroscopic guidance through 18 Fr sheath using semirigid ureteroscope (8.5/11.5 Fr) and pneumatic lithotripter. All patients were followed-up for 2-3 years...

Holt-Oram syndrome (HOS) is a rare autosomal dominant disorder, characterized by upper limb dysplasia and congenital cardiac defect. We report two cases with HOS, first associated with renal agenesis, coronal hypospadias, urethral duplication and second associated with duodenal atresia and horseshoe kidney that have not been reported in English literature.

Congenital renal malformations are the most common congenital malformations in humans, the most common being horseshoe kidney with joined lower poles present in up to 0.25% of general population. To the contrary renal fusions with ectopia are amongst the rare malformations affecting 1 in 2000 examined cadavers. Males are affected slightly more often then females (3:2), left to right crosses being more frequent. The value of early diagnosis of asymptomatic renal malformation is uncertain, except when other abnormalities might point to them and they can affect the clinical management strategy (severe ear deformity with facial malformation, gynecological abnormalities)...

OBJECTIVE: Pre-existing renal lesions (PERL) may interfere with the patho-physiology of trauma, alter the radiographic imaging and influence the therapeutic approach. The aims of this study were to record the PERL found incidentally during blunt renal trauma, to specify the place for effective conservative management and to determin the estimated partial permanent disability (PPD). PATIENTS AND METHODS: The medical records of 14 patients with PERL and blunt renal trauma were reviewed...

OBJECTIVE: To assess the safety and efficacy of retroperitoneoscopy technique-assisted percutaneous nephrolithotomy (PCNL) used in the treatment of complexity horseshoe kidney (HSK) with renal stones. METHODS: Between January 2012 and April 2015, 5 patients with renal stones in complexity HSK underwent retroperitoneoscopy technique-assisted PCNL. The perioperative data analyzed, included operation time, blood loss, incidence of complication rate, the stone-free rate (SFR), and so on...

The objective of this study is to assess the utility of the Guy, S.T.O.N.E., and CROES nephrolithometry scoring systems (SS), and compare the capability of each system to predict percutaneous nephrolithotomy (PNL) outcome in patients with anatomical abnormalities. We retrospectively collected medical records of patients with anatomical abnormalities who underwent PNL for the treatment of renal calculi by experienced surgical teams in four referral centers. All of the patients were graded by a single observer from each department based on preoperative computed tomography images using each SS...

Horseshoe kidney (HSK) is the most common congenital renal fusion anomaly with approximate incidence of 1:400 to 1:1000 births. Pelvic-ureteric junction obstruction (PUJO) occurs in 15-33% of patients in this population. Herein, we report our experience of management of PUJO in HSK by retroperitoneoscopic pyeloplasty.

INTRODUCTION: Acute arterial thromboembolism to the renal arteries can be treated promptly by local thrombolysis, conventional surgical thrombectomy, or by anticoagulation. METHODS: We report a patient who presented with acute loin pain as a result of atrial fibrillation related thrombo-embolism to right renal artery supplying his horseshoe kidney. He was already on warfarin treatment with INR of 1.7 and had acute bleeding from malignant peptic ulcer disease, so thrombolysis was contraindicated...

Horseshoe kidneys are a common, yet enigmatic, renal malformation. This review critically appraised the literature surrounding the embryology, etiology and clinical anatomy of horseshoe kidneys. The systematic literature search produced 104 articles, and 56 primary and further secondary references. There were several etiological theories regarding horseshoe kidneys. The established view was that during ascent, the kidneys come into close apposition as they pass through an arterial fork. Another possible mechanism related to lateral flexion of the trunk or rotation of the caudal embryo; the association of asymmetrical horseshoe kidneys with a number of vertebral conditions supported this hypothesis...

INTRODUCTION: Flexible uretero-renoscopy (FURS) is an accepted modality for management of renal calculi in orthotopically placed kidney. Though it has been used in management of calculi in anomalous kidneys, the literature is scarce. AIM AND OBJECTIVE: To define the role of FURS in the management of stones in anomalous kidneys. MATERIALS AND METHODS: We performed a retrospective analysis of all the patients with anomalous kidneys who primarily underwent FURS from January 2010 to December 2015 at our institute...

OBJECTIVE: Our aim was to report the importance of an awareness of renal artery variations if surgical procedures are indicated in this region. Presentation and Intervention: A 41-year-old female patient was admitted to our hospital for preoperative staging of the rectum carcinoma. A computed tomography (CT) scan clearly revealed the presence of normally positioned small right and left renal arteries, and a large aberrant renal artery originating from the distal abdominal aorta in a case with a horseshoe kidney (HSK)...

Horseshoe kidney is a relatively common congenital anomaly. In 95% of the cases, lower poles are connected to each other. In a small subset, an isthmus connects both upper poles (reverse horseshoe kidney). Almost always, the fusion of kidney poles occurs anterior to the aorta and vena cava. The fusion of renal poles posterior to both aorta and vena cava is extremely rare. Herein, we present a case with multiple rare congenital anomalies-retroaortic variant of reverse horseshoe kidney, retroaortic left renal vein, and butterfly vertebrae...

We reviewed retrospectively the results of transperitoneal minilaparoscopic pyeloplasty in children younger than 2 years. The surgical technique utilized as well as the retrograde placement of the stent is described in detail. Twenty-four consecutive children with a mean age of 7.9 months (range 1-23), a mean weight of 7.4 kg (range 4-12), and a mean follow-up of 18 months (range 3-59) are included. Preoperative grade of dilatation was 3.8 (SFU scale) and postoperatively improved to 1.5. The AP diameter of the pelvis decreased from a mean of 28-9 mm...

Horseshoe kidney (HSK) is the most common fusion anomaly of kidneys. Diagnosis of horseshoe kidneys is made by the demonstration of an isthmus or band of renal tissue between the lower poles of the kidneys. Connection between the upper poles of the kidneys is extremely rare. Several types of skeletal anomalies can be seen concomitantly with HSK. In our present case, where the patient was a 3-year-old male, the connection of renal tissue was located between the upper poles of the kidneys. Furthermore, there was an accompanying spina bifida and Gibbus deformity secondary to anterior hypoplasia of the T10 vertebral body...
