Ureteritis cystica UC , also known as cystic pyeloureteritis, is a rare benign condition due to chronic upper renal tract inflammation 1 , 2. It is asymptomatic and was initially described in by the Italian anatomist Giovanni Battista Morggani 2 , 3. Another rare condition is benign ureteral lesions, as most ureteral tumors are malignant and derived from the urothelium 4 , 5. The aim of this study is to report the case of a patient with simultaneous UC and a benign ureteral tumor.

The Journal publishes articles on basic or clinical research relating to nephrology, arterial hypertension, dialysis and kidney transplants. It is governed by the peer review system and all original papers are subject to internal assessment and external reviews. The journal accepts submissions of articles in English and in Spanish languages.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years.
CiteScore measures average citations received per document published. Read more. SRJ is a prestige metric based on the idea that not all citations are the same.
SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Horseshoe kidney HK was first described by Berengario da Carpo in We present the case of a year-old male, who came to the emergency department for abdominal pain located in the left flank.
From his medical record, we discovered that he had a recent history of arterial hypertension AHT. We performed an abdominal ultrasound not shown in which cystic images were observed on the superior pole of the left kidney, which presented with a mild cortical atrophy.
Given that a kidney disease was suspected, a computerised tomography CT scan was performed, showing that the cystic images corresponded to dilation of the pyelocaliceal system Figure 1 in a HK Figure 2. We performed a left pyeloplasty which resolved the obstructive problems: the patient being asymptomatic at present. HK is the most common type of renal fusion anomaly.
It appears in 1 out of every births, with a higher incidence in men The isthmus is usually located anterior to the large abdominal vessels. Hydronephrosis due to obstruction in the pyeloureteral junction is observed in a third of all HK, being factors which contribute to the upper ureter entering the renal pelvis and isthmus or blood supply anomalies. It can be associated with congenital, genito-urinary, bone, gastrointestinal, myelomeningocele and cardiovascular anomalies.
Pyeloureteral junction stenosis PJS is the most common congenital alteration of the upper urinary tract, and is most associated with HK. In most cases, PJS is due to a destruction of the muscular fibres and an increase in the amount of collagen in the pyeloureteral junction.
The most common clinical sign is lumbar back pain, but for chronic obstruction, activation of the renin-aldosterone system would lead to vasoconstriction of the afferent arteriole, with a consequent reduction in renal blood flow and AHT developing. In spite of this, given hydronephrosis and HK, the most common cause is lithiasis, followed by PS. CT with modern multidetectors can perform a multiplanar reconstruction and confirm the diagnosis given the ultrasound finding, whereas renal gammagraphy is used to find out whether the parenchyma is functioning correctly.
Treatment is performed using laparoscopic and endoscopic pyeloplasty in any of its variants. At present, robotic surgery has proven its utility in obtaining good pyeloplasty results for primary and secondary stenosis, both for children and adults and for different causes. Abdominal CT scans are a good diagnostic method for assessing this condition.
