The management of renal tumors ≤ 4 cm in elderly population or patients with comorbidities is a challenge, for which ablative therapies are an interesting alternative. The objective is to evaluate in our center the role of percutaneous radiofrequency in the treatment of small renal masses, the associated complications and the results obtained.Retrospective evaluation of the radiofrequency treatments carried out between April 2010 and April 2020 in our center. Demographic data, associated comorbidities, tumor characteristics, complications and oncological and functional outcomes were reviewed.Fifty-seven tumors were treated in 53 patients. Mean follow-up of 48.2 months. The percentage of complete ablations obtained was of 89.5%. There were 19.3% of complications. According to Clavien-Dindo and SIR classification systems, 3.5% and 5.3% were major complications. A statistically significant association was found between the initial result of ablation and age (p = 0.047), RENAL-m (p = 0.044), the presence of cystic component (p = 0.049) and tumor size (p = 0.01). The cut-off point for size was established at 25 mm (p = 0.012). In multivariate analysis, only size remained as a predictor of initial ablation result (p = 0.01; OR 1.183; CI 95% 1.041-1.345). Cancer-specific survival and 5-year recurrence-free survival were 98.1% and 89.5%, respectively. A mean decrease of MDRD-4 of 6.59 mL/min (p = 0.005) was observed in the first six months after RFA.Given the excellent oncological and functional results demonstrated, ultrasound-guided percutaneous radiofrequency ablation is an effective and safe treatment for small renal masses in selected patients.

Purpose: To analyze the utility of helical computed tomography (CT) in the diagnosis of suspected upper esophageal foreign bodies. Material and Methods: A prospective study was performed on 36 patients (26 F, 10 M, mean age 70 years) with a history of foreign body impaction. All had negative findings at indirect laryngoscopy. Radiologic assessment included unenhanced helical CT and a barium contrast study. Patients with positive findings were taken to esophagoscopy. All patients had a posterior clinical surveillance. Results: Twenty patients had both normal CT and barium study and satisfactory clinical outcome. In 12 patients a foreign body was noted in the cervical esophagus by CT, barium study, and endoscopy. In one patient a fish bone was detected by CT (and not by barium) confirmed with esophagoscopy. Another patient had a fish bone esophageal perforation which was observed only by CT and confirmed at surgery. Two patients with normal barium and endoscopy presented a false‐positive CT result. Conclusion: Barium swallow is currently the first radiologic study, but may involve a risk of aspiration and can impede a subsequent esophagoscopy. Esophagoscopy is an invasive technique with a certain risk of serious complications that can be avoided with a satisfactory radiologic assessment. CT is easy, fast, has 100% sensitivity and is therefore the first choice technique for diagnosing suspected upper esophageal foreign bodies not expected to be visible on plain radiographs.

To analyze the role of transrectal ultrasound in the diagnosis of diverticula of the female urethra.Transrectal ultrasound assessment was performed with a biplanar 5 MHz probe and translabial ultrasound was performed with a 7 MHz linear or 3.5 MHz sectorial transducer in 9 women suspected to have urethral diverticula. Cystourethrography was also performed in three patients. Eleven diverticula were found in these 9 patients.The incidence of diverticula of the female urethra has been reported to range from 0.5-6%. Diagnosis is confirmed by urethroscopy or imaging methods. Transrectal ultrasound is the method of choice in the assessment of urethral diverticulum.

For the first time in literature we present a case with obstructive renal insufficiency produced by high-pressure ascites in a 38 year old female. Urography and computed tomography demonstrated a large prolapse of the pelvic floor causing obstruction of ureters. Even when the pelvic prolapse is a well known cause of ureterohydronephrosis, in this case it was the high pressure that produced the bilateral obstruction of ureters—that were not compressed by the uterus. Paracentesis improved the renal function of the patient. Thus, ascites could be listed as a very rare but possible cause of hydronephrosis. [Copyright &y& Elsevier]

- Abstract
Objective: To report two Zinner`s syndrome cases, a rare anatomical variant with risk of complications., Methods: Analysis of two Zinner syndrome cases, detected during acute recurrent epididimytis and after a grade IV renal trauma. Review of the literature focusing on its diagnosis and possible complications., Results: The conservative management of the polytrauma patient allowed to preserve the kidney, while maintaining normal renal function. It is the first Zinner`s syndrome diagnosed in this clinical context., Conclusions: Zinner`s syndrome is a rare entity and often goes unnoticed because of the few symptoms it produces.

- Abstract
The congenital absence of the major salivary glands is a very infrequent disorder, in which several glands are usually involved at the same time. Sometimes this disorder can be associated with other developmental anomalies. The unilateral aplasia of the submandibular gland is an extremely rare finding with only 14 cases reported in the literature. Clinically, this kind of patients may complain of dryness of the mouth, difficulties in chewing and swallowing, severe periodontal disease or multiple caries, but usually they follow an asymptomatic course. Salivary gland aplasia can be diagnosed with a large variety of imaging techniques, which include computer tomography (CT), magnetic resonance imaging (MR), ultrasonography (US), sialography, or scintigraphy. In this paper we report a case of a patient referred to our department with a long term and progressive growing neck mass, who has an unilateral submandibular gland aplasia associated to an ipsilateral hypertrophy of the sublingual gland.
