RESUMO

Adrenal pseudocysts are rare, nonfunctional, asymptomatic cystic masses that originate from the adrenal gland and are usually located in the suprarenal area. They are usually incidentally discovered during imaging, but diagnosis can be challenging because they are similar to benign and malignant cystic lesions of the adrenal gland and adjacent organs. We describe a giant, adrenal hemorrhagic pseudocyst that was atypically located, extending from the middle to the lower poles of the kidney, admixed with a renal cortical cyst.

RESUMO

INTRODUCTION: We evaluated the bladder oxidative stress in neurogenic bladder children treated with intravesical amikacin for recurrent UTI and whether urinary isoprostane f2 alpha (F2-IsoP) is a good biomarker in this particular condition. METHODS: This prospectively designed controlled study was approved by the Adnan Menderes University institutional ethics committee (Adnan Menderes University, 2015/649). Between January 2016 and January 2017, twenty-six children with meningomyelocele who had been doing CIC were recruited. Serum and urine samples were collected during urinary tract infection (UTI) (group 1) and after management of UTI with intravesical amikacin (group 2) besides standard oral antibiotic treatment. While oxidative stress parameters SOD, GSH, GPX, MDA, F2-IsoP and NO were analyzed in the serum samples, only F2-IsoP was analyzed in the urine. All data were compared with 23 normal healthy control children (group 3). RESULTS: Median age, CIC duration and number of CIC per day of patients' group were 84 (60-147) months, 60 (30-90) months and 4 (4-6), respectively. Male-to-female ratio was 1:16. There was no statistical difference between groups in terms of serum oxidative stress parameters (p > 0.05). However, statistically significant urine F2-IsoP changes exist between groups (p = 0.011) (Fig. 1). But there were no correlations between urine F2-IsoP and disease clinical data such as CIC duration or number of CIC per day. Serum glutathione levels in group 2 were higher than group 1 and 3, as well (p = 0.023, Kruskal-Wallis test). Fig. 1 Comparison of median urinary isoprostane f2 alpha levels CONCLUSION: Higher urine F2-IsoP levels after management of UTI with intravesical amikacin may reflect increased lipid peroxidation and oxidative stress in children with NB. This detrimental effect on bladder should be considered in the long-term treatment period.

RESUMO

BACKGROUND: To distinguish RCC subtypes based on contrast enhancement features of CT images. MATERIAL/METHODS: In total, 59 lesions from 57 patients were included. All patients underwent multi-slice CT imaging with a triphasic protocol, which included non-contrast, corticomedullary, nephrographic and urographic phases. Contrast enhancement features of renal masses were evaluated in terms of CT attenuation values (AV) and differences in contrast density; the aorta or renal parenchyma were evaluated based on corrected or relative values. RESULTS: Clear cell RCC (ccRCC) showed more intense contrast enhancement than other RCC subtypes. When differentiating ccRCC from other RCC subtypes, a cut-off AV of 86-89 HU, aorta-based corrected AV of 89-95 HU and renal parenchyma-based corrected AV of 87-95 HU showed a diagnostic accuracy of 81-86%, 86-88% and 74-78%, respectively, in the corticomedullary phase. Furthermore, a cutoff of 2.42-2.72 for the relative contrast enhancement ratio, a cutoff of 2.59-2.74 for the aorta-based corrected relative contrast enhancement ratio and a cutoff of 2.63-2.76 for the renal parenchyma-based attenuation ratio showed a diagnostic accuracy of 83-88%, 88-90% and 81%, respectively. CONCLUSIONS: The most reliable parameters for differentiating ccRCC from other RCC subtypes are aorta-based corrected AV and aorta-based corrected relative contrast enhancement values in the corticomedullary phase.

RESUMO

Laparoscopic pyeloplasty (LP) for ureteropelvic junction obstruction (UPJO) is one of the most appropriate surgical techniques to achieve the optimal goal of minimally invasive surgery. However, urologists hesitate to use the laparoscopic approach in UPJO with solitary kidney or intrarenal pelvis. There are a few published studies on laparoscopic pyeloplasty cases in intrarenal pelvis. However, to the best of our knowledge, the present case is the first in the literature in terms of intrarenal pelvis in a solitary kidney. Generally, YV plasty is the accepted technique instead of dismembered pyeloplasty in UPJO with small or intrarenal pelvis. However, in this report, we showed that dismembered LP can be performed with good results in intrarenal pelvis UPJO, even if it is in the solitary kidney.

RESUMO

Metastatic testicular cancers are rare. Primary tumor sources are prostate, lung, and gastrointestinal tract for metastatic testicular cancers. Metastasis of urothelial carcinoma (UC) to the testis is extremely rare. Two-thirds of upper tract urothelial carcinoma (UTUC) is of invasive stage at diagnosis and metastatic sites are the pelvic lymph nodes, liver, lung, and bone. We report a rare case of metastatic UTUC to the testis which has not been reported before, except one case in the literature. Testicular metastasis of UC should be considered in patients with hematuria and testicular swelling.

RESUMO

Adequate nutrition is imperative for a successful outcome in dialysis patients. Excellent oral hygiene and an efficient mastication can help to correct several metabolic and endocrine disturbances as well as delay initiation of dialysis in patients with chronic renal failure. However, concerns exist about the risk of malnutrition and protein depletion. On the other hand, intravenous bisphosphonates are the current standard of care for the treatment of hypercalcemia of malignancy and for the prevention of skeletal complications associated with bone metastases. Recently, retrospective case studies have reported an association between long-term bisphosphonate therapy and osteonecrosis of the jaws. This complication occurs either spontaneously or after minor dento-alveolar surgery including extraction of teeth. A malnourished dialysis patient who showed the typical clinical features of bisphosphonate-related osteonecrosis of the jaw (BRONJ) without any obvious radiological changes in his panoramic radiograph is reported. To minimize the risk of BRONJ, patients initiated on bisphosphonates should optimize routine dental care and have their baseline oral health evaluated by both clinical and radiographic examinations before initiation of bisphosphonate therapy.

RESUMO

The aim of this study was to evaluate the relationship between lower urinary tract symptoms (LUTSs), erectile dysfunction (ED) and symptomatic late-onset hypogonadism (SLOH) in ageing men in the Aegean region of Turkey. Five hundred consecutive patients >40 years old who had been in a steady sexual relationship for the past 6 months and were admitted to one of six urology clinics were included in the study. Serum prostate-specific antigen and testosterone levels and urinary flow rates were measured. All patients filled out the International Prostate Symptom Score and Quality of Life (IPSS-QoL), International Index of Erectile Function (IIEF) and Aging Males' Symptoms (AMS) scale forms. Of the patients, 23.9% had mild LUTSs, 53.3% had moderate LUTSs and 22.8% had severe LUTSs. The total testosterone level did not differ between groups. Additionally, 69.6% had ED. The presence of impotence increased with increasing LUTS severity. Symptomatic late-onset hypogonadism (AMS >27) was observed in 71.2% of the patients. The prevalence of severe hypogonadism symptoms increased with the IPSS scores. A correlation analysis revealed that all three questionnaire scores were significantly correlated. In conclusion, LUTS severity is an age-independent risk factor for ED and SLOH. LUTS severity and SLOH symptoms appear to have a strong link that requires etiological and biological clarification in future studies.

RESUMO

PURPOSE: To assess the efficiency of the following imaging algorithm, including intravenous urography (IVU) or computed tomography urography (CTU) based on ultrasonographic (US) selection, in the radiological management of hematuria. MATERIALS AND METHODS: One hundred and forty-one patients with hematuria were prospectively evaluated. Group 1 included 106 cases with normal or nearly normal US result and then they were examined with IVU. Group 2 was composed of the remaining 35 cases which had any urinary tract abnormality, and they were directed to CTU. Radiological results were compared with clinical diagnosis. RESULTS: Ultrasonography and IVU results of 97 cases were congruent in group 1. Eight simple cysts were detected with US and 1 non-obstructing ureter stone was detected with IVU in remaining 9 patients. The only discordant case in clinical comparison was found to have urinary bladder cancer on conventional cystoscopy. Ultrasonography and CTU results were congruent in 30 cases. Additional lesions were detected with CTU (3 ureter stones, 1 ureter TCC, 1 advanced RCC) in remaining 5 patients. Ultrasonography+CTU combination results were all concordant with clinical diagnosis. Except 1 case, radio-clinical agreement was achieved. CONCLUSION: Cross-sectional imaging modalities are preferred in evaluation of hematuria. CTU is the method of choice; however the limitations preclude using CTU as first line or screening test. Ultrasonography is now being accepted as a first line imaging modality with the increased sensitivity in mass detection compared to IVU. The US guided imaging algorithm can be used effectively in radiological approach to hematuria.

RESUMO

OBJECTIVE: The primary aim was to evaluate the change in the total and free PSA levels after antibiotic and non-steroid anti-inflammatory treatment. The secondary aim was to compare this change among the histological subgroups to assess whether it was discriminating. METHODS: 97 consecutive patients with PSA >4 ng/dl and scheduled for prostate biopsy were included in this prospective study. 65 patients (group 1) were then put on medical treatment of ciprofloxacin 500 mg bid and diclofenac sodium 75 mg during the routine waiting period before the 2- to 3-week procedure. Randomly selected (every third case) 32 patients (group 2) did not receive this treatment. Free and total PSA tests were repeated before the procedure. The change in the PSA values was compared between the groups and among the histological subgroups in group 1. RESULTS: While in group 1 the decrease in PSA was significant (p = 0.000), this was not the case in group 2. The difference in free PSA values was unremarkable for both groups. In histologically determined cancer cases of group 1, the difference between pre- and post-procedure PSA level was not of note, while in BPH and prostatitis cases it was significant. CONCLUSION: In cases with increased PSA, medical treatment for a likely subclinical prostatitis resulted in a decrease of PSA, which was significant only in benign conditions.

RESUMO

The aim was to determine the expression of Bax in germ cells of rats with unilateral experimental cryptorchidism, and to evaluate the role of apoptosis in germ cell loss. Twenty-one prepubertal rats were randomly subdivided into three groups after the execution of the left cryptorchidism model. Group 1 (n=8), group 2 (n=6) and group 3 (n=7) rats were killed at the end of the first, second and third month, respectively. Bax expression was assessed in Sertoli cells, spermatogonia and spermatocytes by immunohistochemistry. Percentages of Bax expression in spermatocytes and spermatogonia were decreased in the left testicles in the 2nd and 3rd months compared to results obtained in the 1st month (p<0.05). Percentage of Bax expression in the left testicles of group 1, at the level of both spermatogonia and spermatocytes was higher than that in the right one (p<0.05). However, in groups 2 and 3, the higher Bax expression on the left side was only seen in the spermatocytes (p<0.05). In all groups, the mean weight of the left testicle was lower than that of the scrotal counterpart where the difference was significant only in groups 1 and 3 (p<0.05). The weight of the left and right testicles was increasing with time. In this model of cryptorchidism, the affected testis had a decreased weight compared to the normal one. Based on the increased Bax expression, we think that apoptosis may play a role in the germ cell loss.

RESUMO

OBJECTIVE: To characterize the hypoechoic prostate nodules in the peripheral zone by means of power Doppler ultrasonography (PDUS) and contrast enhanced PDUS (CE-PDUS). MATERIALS AND METHODS: Thirty-two patients with dijital rectal examination findings suspicious for malignancy and/or a serum PSA level higher than 4 ng/dl, and who had hypoechoic nodules on transrectal ultrasonography were enrolled in this prospective study. Power Doppler ultrasonography (PDUS) images before and after sonocontrast (Levovist) injection were photographed for further evaluation. All patients were also evaluated by a systematic and nodule targeted biopsy approach. The photographs were re-evaluated by two radiologists for the presence and type of vascularity. The type of vascularity was categorized as peripheral, central, mixed and penetrating. The latter two were accepted as representatives of malignancy. The results of PDUS and CE-PDUS were compared to each other and to the pathological results. RESULTS: There was a high level of interobserver agreement (Kappa: 0.80-0.95). Nineteen patients, but only 14 nodules were malignant on pathological examination. Sensitivity, specificity positive and negative predictive values for PDUS were 57, 50, 47, and 60%, respectively. On CE-PDUS, the sensitivity increased (93%) in expense of specifity (17%). The positive and negative predictive values were 46 and 75%, respectively. There was no significant difference between PDUS and CE-PDUS. CONCLUSION: This study revealed that both benign and malignant nodules might be hypervascular and show malignant type of vascularity on PDUS. Contrary to some recent reports, we can conclude that the CE-PDUS does not provide a considerable aid to the diagnosis of prostate carcinoma on morphological basis due to its very low specificity despite its relatively higher sensitivity.
