To our knowledge, this is the first reported case of renal cell carcinoma in kidney horseshoe diagnosed in the second trimester of pregnancy. We performed open radical nephrectomy when the pregnancy was completed. Kidney cancer is rare during pregnancy and the symptoms can be mimic urinary infection. The diagnosis and its management can be a challenge.

A 76-year-old man was introduced to our department with a right kidney stone. On the basis of further examination, he was diagnosed with a 23 mm right kidney stone accompanied with a horseshoe kidney. Retrograde pyelography and diuretic renogram revealed a non-obstructed right ureteropelvic junction. Finally, we chose laparoscopic pyelolithotomy via peritoneal approach because the stone was large and accompanied with a horseshoe kidney. The surgery took 165 minutes and the estimated blood loss was 25 ml. There were no minor or major complications...

Renal replacement lipomatosis (RRL) is a rare condition that occurs at the end of the spectrum of renal tissue replacement by fat. Xanthogranulomatous pyelonephritis (XGP) is a granulomatous inflammation characterized by destruction of renal parenchyma and replacement by lipid-laden macrophages. We present the case of a 75-year-old man who complained of severe anemia 34 years after right nephrolithotomy. Computed tomography revealed a huge low-density mass with renal parenchyma atrophy on the right side of horseshoe kidney...

Clear cell sarcoma of kidney (CCSK) is a rare renal malignancy, previously unreported in horseshoe kidney (HSK). B-cell lymphoma 6 corepressor (BCOR) gene internal tandem duplication (ITD) was identified as a recurrent somatic alteration in approximately 85% of CCSKs. This and the YWHAE-NUTM2B/E fusion, the second most common recurrent molecular alteration in CCSK (10%), are considered to be mutually exclusive. However, there is a subset of CCSKs that do not harbor either the BCOR-ITD or YWHAE-NUTM2 translocation and lack known molecular alterations...

Horseshoe kidney is the most common renal fusion anomaly found in about 0.15% to 0.25% of the population. Renal cell carcinoma associated with a horseshoe kidney has been described in fewer than 200 cases. Its incidence and prognosis seems to be not different from those of the general population, but surgical management may be challenging due to unique anatomic features of horseshoe kidneys, such as highly variable vasculature. We report a case of a 69-year-old male with an incidental 48-mm solid mass in the left moiety of a horseshoe kidney, successfully treated by retroperitoneoscopic partial nephrectomy...

In the context of ante-natally diagnosed hydronephrosis, the vast majority of children with a dilated renal pelvis do not need any surgical treatment, as the dilatation resolves spontaneously with time. Slow drainage demonstrated at Tc-99m-mercaptoacetyltriglycine (MAG3) renography does not necessarily mean obstruction. Obstruction is defined as resistance to urinary outflow with urinary stasis at the level of the pelvic-ureteric junction (PUJ) which, if left untreated, will damage the kidney. Unfortunately this definition is retrospective and not clinically helpful...

Trauma refers to the destruction of tissues or organs by external forces and it is the most common cause of mortality and morbidity in children (1, 2). Injuries of the genitourinary tract may be the result of blunt (falls, sport injuries, motor vehicle accidents and sexual abuse) or penetrating (stab wounds, gun shots, falling onto sharp objects) injuries. The genitourinary tract is significantly injured in 2.9% of paediatric trauma patients 4.In the paediatric population, the kidney is the most affected organ in the genitourinary tract (>60% of all genitourinary tract injuries) 4...

In spite of the fact that urologic surgical techniques used by urologists are becoming more and more minimally invasive and easier because of developing technologies, surgical approaches for the urinary stones in kidneys with abnormal anatomy are still confusing. The objective of this article is to determine the treatment options in these kidneys. For this purpose, between 2005 and 2015, we retrospectively evaluated patients operated for urolithiasis with various congenital renal anomalies in five referral urology clinics in our country...

Between June 2006 and January 2016, 6 renal cryoablation procedures were performed in 5 patients with horseshoe kidneys. Renal cell carcinoma (RCC) accounted for 5 of the tumors, and the sixth was a carcinoid tumor. All 6 procedures were technically successful. The patient with the carcinoid tumor developed local tumor progression 38 months after ablation. Technique effectiveness was achieved in all 5 patients with RCC. Two complications occurred: obstructive hematuria and transient inguinal neuralgia after ablation...

PUF60 encodes a nucleic acid-binding protein, a component of multimeric complexes regulating RNA splicing and transcription. In 2013, patients with microdeletions of chromosome 8q24.3 including PUF60 were found to have developmental delay, microcephaly, craniofacial, renal and cardiac defects. Very similar phenotypes have been described in six patients with variants in PUF60, suggesting that it underlies the syndrome. We report 12 additional patients with PUF60 variants who were ascertained using exome sequencing: six through the Deciphering Developmental Disorders Study and six through similar projects...

Transplantation of the horseshoe kidney can be performed en bloc or split into 2 grafts according to the vascular anomaly and the existence of the urinary collecting system in isthmus. From 2011 to 2014, there were 3 horseshoe kidney transplantations in Korea and transplantations were performed at 2 different centers. The transplantations were carried out successfully for all recipients without complications. All recipients have shown good graft kidney function after transplantation. No severe complication was revealed during follow-up period...

Bilateral agenesis of the diaphragm is a very rare congenital diaphragmatic defect. Bilateral congenital diaphragmatic hernia (CDH) is much more frequently associated with other anomalies compared with unilateral CDH (70% vs 30%-40%). These include cardiovascular, respiratory (other than lung hypoplasia), gastrointestinal, renal, and genital malformations. We report a case of complete bilateral agenesis of the diaphragm associated with a horseshoe kidney and an imperforate anus. These additional malformations have not previously been reported in association with complete bilateral agenesis of the diaphragm...

AIM: Horseshoe kidney is often associated with other congenital abnormalities and obstruction of pyeloureteral segment (PUS). The aim of our study was to evaluate the results of laparoscopic pyeloplasty (LP) in patients with hydronephrosis of horseshoe kidney. MATERIALS AND METHODS: From February 2010 to March 2016, 130 patients underwent LP. Ten (7.7%) of them (6 men and 4 women) had a hydronephrosis of horseshoe kidney. Left and right PUS obstruction were diagnosed in 6 and 4 patients, respectively...

Ectopic adrenocorticotropic hormone (ACTH) syndrome is characterized by hypercortisolism due to the hypersecretion of a non-pituitary ACTH-secreting tumor leading to Cushing's syndrome. Only a few cases have been reported previously as causing ectopic ACTH related to paraganglioma. Herein, we present a case of Cushing's syndrome, in who was proved to be attributable to an ACTH-secreting renal malignant paraganglioma. A 40-year-old woman presented with a five-month history of newly diagnosed hypertension and diabetes, weakness, hyperpigmentation, oligomenorrhea, hirsutism, and acneiform lesions...

INTRODUCTION: Various anomalous kidneys such as horseshoe kidney, crossed ectopic kidney, simple ectopic kidney, pelvic ectopic kidney, kidney with duplex system, and malrotated kidney are frequently associated with stone disease. Percutaneous nephrolithotomy (PCNL) is a challenging procedure in these patients because of abnormal orientation of kidney. PATIENTS AND METHODS: Since 2005-2015, 86 patients underwent PCNL for stone removal in anomalous kidneys. Stone characteristics, type of calyceal puncture, number of punctures, need of relook procedures, mean hemoglobin drop, blood transfusion, mean operative time complications, mean hospital stay, stone free rate, and auxiliary procedure were analyzed...

We report a case of supernumerary kidney associated with horseshoe malformation. A 35-year-old man presented complaining of vague and intermittent left flank pain from few months ago. Ultrasonography of urinary tract showed bilateral hydronephrosis and was suggestive of the horseshoe anomaly. Further evaluation with Intravenous urography showed three renal moieties consisting of a horseshoe kidney and a malrotated right kidney cephalad to and fused with the right moiety of horseshoe kidney.

A horseshoe kidney (HSK) is the most common congenital renal fusion anomaly. HSKs are more likely than normal kidneys to have associated problems of stones, ureteropelvic junction obstruction, stasis and infection. However, they do not have an increased incidence of renal cell carcinoma when compared to normal kidneys. Due to its rarity, accurate diagnosis may be difficult. Of similar significance is the fact that problems may arise during surgery on these kidneys due to altered anatomy and aberrant blood supply...
