RESUMEN
We aim to investigate the prognostic significance of the hemoglobin X lymphocyte / neutrophil ratio (HLNR) and hemoglobin x lymphocyte / platelet ratio (HLPR) with tumor aggressivity in patients with renal cell carcinoma. We retrospectively analyzed 127 patients' data who had diagnosed as renal cell carcinoma between 2008 and 2019 in Suleyman Demirel University Hospital. Tumor and patient characteristics, hemoglobin, neutrophil, lymphocyte, platelet values HLNR and HLPR were calculated in preoperative hemogram parameters. The relationship between tumor pathological stage, Fuhrman nuclear grade and tumor necrosis with HLPR and HLNR analyzed with statistically. There was a negative correlation between pathologic stage, Fuhrman nuclear grade and tumor necrosis with HLNR. P values are 0.003, 0.012 and 0.015 respectively. HLNR was lower in patients with high pathologic stage, high Fuhrman nuclear grade and accompanying tumor necrosis positiveness. There was a negative correlation between pathologic stage, Fuhrman nuclear grade and tumor necrosis with HLPR. P values are 0.001, 0.014 and 0.047 respectively. HLPR was lower in patients with high pathologic stage, high Fuhrman nuclear grade and accompanying tumor necrosis positiveness. High pathological stage, high Fuhrman nuclear grade and existence of tumor necrosis are associates with preoperative low HLNR and low HLPR in renal cell carcinoma patients. They can be used as prognostic markers in patients with renal mass preoperatively.

OBJECTIVES: Fibromyalgia (FM) can cause neuropsychiatric symptoms and sexual dysfunction. However, no data exist regarding anxiety and depression status in spouses of sexually active women with FM. Accordingly, we aimed to evaluate whether emotional status are affected in spouses of women with FM, and to search whether there was a relationship between sexual dysfunction of women with FM and emotional status of their spouses. METHODS: Thirty newly diagnosed, never treated reproductive women with FM and 30 age-matched healthy women as well as their spouses were included. Psychological status was evaluated using Beck depression/anxiety inventory (BDI/BAI). Sexual function was evaluated using Female Sexual Function Index (FSFI) and Index of Female Sexual Function (IFSF). RESULTS: BDI, BAI, FSFI and IFSF scores were significantly higher in women with FM than in controls. The spouses of women with FM had increased BDI and BAI scores as compared to spouses of controls (7.10 ± 7.76 vs. 2.10 ± 2.68, 6.96 ± 6.62 vs. 2.20 ± 3.16, respectively, p<0.001). BDI scores of women with FM significantly correlated to BDI scores of their spouses, but there was no significant relationship between BDI scores of spouses and sexual functions of women with FM. CONCLUSIONS: FM can cause deterioration of emotional status and lead to sexual dysfunction. Also, psychological status could be affected in spouses of women with FM at reproductive age, and the severity of depression of their spouses was significantly correlated to that of women with FM. However, this affection in psychological status did not relate to sexual problems of the women with FM.

OBJECTIVES: The aim of the present study is to evaluate mental workload and fatigue in fingers, hand, arm, shoulder in single-incision laparoscopic surgery (SILS) and multiport laparoscopy. METHODS: Volunteers performed chosen tasks by standard laparoscopy and SILS. Time to complete tasks and finger and hand strength were evaluated. Lateral, tripod, and pulp pinch strengths were measured. Hand dexterity was determined by pegboard. Electromyography recordings were taken from biceps and deltoid muscles of both extremities. The main outcome measurement was median frequency (MF) slope. NASA-TLX was used for mental workload. RESULTS: Time to complete laparoscopic tasks were longer in the SILS group (P < .05). Decrease of strength in fingers and hand were similar in SILS and standard laparoscopy. Pegboard time was increased in both hands after SILS (P < .05). MF slope of biceps muscle and deltoid muscle in SILS was far away from the reference slope. MF slope of biceps muscle and deltoid muscle in standard laparoscopy was close to reference slope, indicating there was more fatigue in biceps and deltoid muscles of both upper extremities in SILS group. NASA-TLX score was 73 ± 13.3 and 42 ± 19.5 in SILS and multiport laparoscopy, respectively (P < .01). Mental demand, physical demand, temporal demand, performance, effort, and frustration were, respectively, scored 10.7 ± 3.8, 11.7 ± 3.5, 12.2 ± 2.7, 11 ± 3, 13.6 ± 2.7, and 13.5 ± 2.8 in SILS and 6.3 ± 3.1, 6.6 ± 3.3, 7.3 ± 3.3, 7.1 ± 4.1, 7.9 ± 3.9, and 6.6 ± 3.8 in standard laparoscopy (P < .01). CONCLUSIONS: SILS is mentally and physically demanding, particularly on arms and shoulders. Fatigue of big muscles, effort, and frustration were major challenges of SILS. Ergonomic intervention of instruments are needed to decrease mental and physical workload.

We aimed to evaluate the cancer detection rates of 6-, 10-, 12-core biopsy regimens and the optimal biopsy protocol for prostate cancer diagnosis in patients with renal failure. A total of 122 consecutive patients with renal failure underwent biopsy with age-specific prostate-specific antigen (PSA) levels up to 20 ng/mL. The 12-core biopsy technique (sextant biopsy + lateral base, lateral mid-zone, lateral apex, bilaterally) performed to all patients. Pathology results were examined separately for each sextant, 10-core that exclude parasagittal mid-zones from 12-cores (10a), 10-core that exclude apex zones from 12-cores (10b) and 12-core biopsy regimens. Of 122 patients, 37 (30.3%) were positive for prostate cancer. The cancer detection rates for sextant, 10a, 10b and 12 cores were 17.2%, 29%, 23.7% and 30.7%, respectively. Biopsy techniques of 10a, 10b and 12 cores increased the cancer detection rates by 40%, 27.5% and 43.2% among the sextant technique, respectively. Biopsy techniques of 10a and 12 cores increased the cancer detection rates by 17.1% and 21.6% among 10b biopsy technique, respectively. There were no statistical differences between 12 core and 10a core about cancer detection rate. Adding lateral cores to sextant biopsy improves the cancer detection rates. In our study, 12-core biopsy technique increases the cancer detection rate by 5.4% among 10a core but that was not statistically different. On the other hand, 12-core biopsy technique includes all biopsy regimens. We therefore suggest 12-core biopsy or minimum 10-core strategy incorporating six peripheral biopsies with elevated age- specific PSA levels up to 20 ng/mL in patients with renal failure.

OBJECTIVE: To compare the ability of the obturator nerve block (ONB) and increased plasma ignition distance practice (IPDP) techniques to inhibit obturator nerve reflex (ONR) occurring with bipolar transurethral resection of the bladder. METHODS: Sixty patients who had a tumor placed at the lateral sidewall or had a tumor in another part of the bladder along with the lateral wall were randomly enrolled. Cystoscopic and ultrasonographic examinations and a computerized tomography scanning of the urinary bladder were used to determine the ONB side. Group 1 consisted of patients who had the ONB procedure. Group 2 consisted of patients who had IPIDP. The severity of the ONR was classified as severe, mild, and very mild. The study's primary endpoint was ONR occurrences and successful completion of the surgery. The secondary endpoints were bleeding and bladder perforation. RESULTS: There was a significant difference in the occurrence of ONR between the two groups (P = 0.0011). However, there was no significant difference between the two groups in the ability to resect the tumor and complete the surgery (P = .764). There was no correlation between the ONR and the tumor size (P = 0.478). CONCLUSION: Our study concluded that both ONB and IPIDP have comparable results, especially in resecting tumors and completing the operation. IPIDP has some advantages over ONB, such as shorter operative time, lower total costs, and less trained personnel requirements.

The aim of this study was to assess the cadmium (Cd) toxicity on renal nitric oxide synthase (NOS) isoenzymes. The study was carried out on 18 inbred male (Cd group: 10 and control group: 8) Wistar rats. Cd group received drinking water containing 15 mg/L Cd for 30 days; and at the end of the 30 days, plasma Cd was analysed. One kidney was snap frozen to assess the endothelial NOS (eNOS), inducible NOS (iNOS) and neuronal NOS (nNOS) expressions by Western blot analyses, and the other kidney was preserved for histopathological examination. Plasma Cd levels were significantly elevated in the Cd group. The Western blot analyses found higher levels of eNOS, iNOS and nNOS in the Cd group but only eNOS and nNOS levels were statistically significant. There was no difference in pathological assessment of the renal tissues. Cd toxicity increases NOS isoenzyme levels and may affect renal physiology.

OBJECTIVE: Using artificial intelligence and a deep learning algorithm can differentiate vesicoureteral reflux and hydronephrosis reliably. MATERIAL AND METHODS: An online dataset of vesicoureteral reflux and hydronephrosis images were abstracted. We developed image analysis and deep learning workflow. The images were trained to distinguish between vesicoureteral reflux and hydronephrosis. The discriminative capability was quantified using receiver-operating characteristic curve analysis. We used Scikit learn to interpret the model. RESULTS: Thirty-nine of the hydronephrosis and 42 of the vesicoureteral reflux images were abstracted from an online dataset. First, we randomly divided the images into training and validation. In this example, we put 68 cases into training and 13 into validation. We did inference on 2 cases and in return their predictions were predicted: [[0.00006]] hydronephrosis, predicted: [[0.99874]] vesicoureteral reflux on 2 test cases. CONCLUSION: This study showed a high-level overview of building a deep neural network for urological image classification. It is concluded that using artificial intelligence with deep learning methods can be applied to differentiate all urological images.
RESUMEN
RATIONALE AND OBJECTIVES: Histological variant (HV) of bladder urothelial carcinoma (UC) is a significant factor for therapy management. We aim to assess the predictive performance of machine learning (ML)-based Computed Tomography radiomics of UC for HV. MATERIALS AND METHODS: Volume of interest of 37 bladder UC tumors, of which 21 were pure and 16 were HV, were manually segmented. The extracted first- and second-order texture features (n = 117) using 3-D Slicer radiomics were compared to the radical cystectomy histopathological results. ML algorithms were performed to determine the significant models using Python 2.3, Pycaret library. The sample size was increased to 74 by synthetic data generation, and three outliers from the training set were removed (training dataset; n = 52, test dataset; n = 19). The predictive performances of 15 ML algorithms were compared. Then, the best two models were evaluated on the test set and ensembled by Voting Classifier. RESULTS: The ML algorithms demonstrated area under curve (AUC) and accuracy ranging 0.79-0.97 and 50%-90%, respectively on the train set. The best models were Gradient Boosting Classifier (AUC: 0.95, accuracy: 90%) and CatBoost Classifier (AUC: 0.97, accuracy: 85%). On the test set; the Voting Classifier of these two models demonstrated AUC, accuracy, recall, precision, and F1 scores as follows; 0.93, 79%, 86%, 67%, and 75%, respectively. CONCLUSION: ML-based Computed Tomography radiomics of UC can predict HV, a prognostic factor that is indeterminable by qualitative radiological evaluation and can be missed in the preoperative histopathological specimens.
RESUMEN
INTRODUCTION: Both hypertension and ß-blocker drugs used for treating hypertension (HT) can cause erectile dysfunction (ED). Nebivolol, unlike other ß-blockers, may not cause impotence since it increases the release of Nitric Oxide (NO), which is the main mediator of erection. This study investigated the effect of Nebivolol and Metoprolol on erectile functions in hypertensive men. MATERIALS AND METHODS: Married men whose blood pressure were >140/90 mmHg were included in the study. All patients were assessed for ED, and the cause of ED was then investigated. Nebivolol or Metoprolol was started for one month in all patients. After one-month drugless period, the ß-blockers were switched. Blood pressures, pulses and sexual function tests were evaluated, and plasma NO levels were measured at the end of the treatments and during the drugless period. RESULTS: There was no difference in antihypertensive efficacy between the two drugs (p = 0.828;0.194 for systolic and diastolic BP). Metoprolol caused a significant decrease in IIEF-5 score, whereas Nebivolol did not cause a decrease in IIEF-5 score on patients with psychogenic, arteriogenic, and venous failure related ED (respectively, p<0.001,0.004,0.005 for Metoprolol; p = 0.201,0.598,0.088 for Nebivolol). In the non-ED group, both drugs decreased the IIEF-5 score, but the decrease for Metoprolol (p = 0.001) was more than that for Nebivolol (p = 0.012). Plasma NO levels did not change with Metoprolol (p = 0.268) but increased with Nebivolol (p<0.001). There was a positive correlation between plasma NO values and IIEF-5 score used for the assessment of sexual functions (r = 0.284, p = 0.026). CONCLUSION: Nebivolol may be advantageous in terms of preserving sexual functions because of increasing NO in eligible hypertensive male patients.

INTRODUCTION: We aimed to evaluate the impact of the resection technique (tumor enucleation (TE) or standard partial nephrectomy (SPN)) on trifecta outcomes in patients having undergone partial nephrectomy (PN). MATERIALS AND METHODS: We retrospectively analyzed the clinical and pathologic parameters in patients with localized renal cell carcinoma (pT1-2N0M0) who had undergone PN between January 2001-December 2018 at one of 15 different tertiary referral centers. Multivariable logistic regression analysis was applied to investigate independent predictors of trifecta failure, decreased postoperative renal functions (decreased estimated glomerular filtration rate (eGFR) > 10%), perioperative complications (Clavien-Dindo > 1), and positive surgical margins. RESULTS: A total of 1070 patients with a mean age 56.11 ± 11.88 years were included in our study. PN was performed with TE in 848 (79.25%) and SPN in 222 (20.75%) patients. Trifecta failure rate was 56.2% for TE and 64.4% for SPN (p = 0.028). On multivariable analysis, TE was associated with less trifecta failure (p = 0.025) and eGFR decrease >10% rates (p = 0.024). On the other hand, there was no statistically significant difference between TE and SPN according to positive surgical margins (p = 0.450) and complication > Clavien-Dindo grade 1 (p = 0.888) rates. The only independent predictive factor for complications > Clavien-Dindo 1 was the Charlson comorbidity index (CCI) (p = 0.001). CONCLUSION: TE is associated with less trifecta failure than SPN. This result is mainly due to better preservation of renal function with TE.

OBJECTIVES: Prostate cancer is the most frequently diagnosed malignancy. Luteinizing hormone-releasing hormone (LH-RH) agonists are used in most patients with locally advanced and metastatic prostate cancer, and decrease testosterone production. We aimed to find out the effects of androgen deprivation therapy with LH-RH agonist on the hand function, quality of life, and mood of the patients with prostate cancer. SUBJECTS: A total of 20 patients with locally advanced prostate cancer and 20 age-matched healthy men were included in the study as LH-RH and control groups, respectively. MAIN MEASURES: Age, body mass index, occupation and dominant hand, physical activity level, Beck depression inventory scores, 15D quality of life questionnaire scores, and Duruoz hand index scores were recorded. Handgrip strength was tested in the dominant hand using the Jamar hand dynamometer (Sammons Preston, Inc., Bollingbrook, IL). The Grooved Pegboard Test was used to test manual dexterity. Serum concentrations of total and free testosterone, estradiol levels were measured. RESULTS: There were no differences between the groups in body mass index, physical activity level, and age (P > 0.05). Serum total and free testosterone, estradiol level, and the mean grip strength score were statistically lower in the LH-RH group. Manual dexterity was diminished in the LH-RH group (P < 0.001). The Duruoz hand index, and Beck depression inventory and 15D quality of life questionnaire scores were statistically lower in the LH-RH group (P < 0.005). We found a correlation between handgrip strength, dexterity, Beck depression inventory scores, 15D quality of life questionnaire scores, and total and free testosterone. CONCLUSION: Men with low testosterone levels caused by androgen deprivation therapy have worse grip strength, dexterity, 15D quality of life questionnaire scores, and depressive symptoms than age-matched men who have not received androgen deprivation therapy.

AIMS: Our purpose was to determine the incidence of electrocardiographic (ECG) abnormalities in patients with organic erectile dysfunction (ED) and to compare the results with an age-matched control (potent) group. METHODS: A total of 218 men with ED of organic etiology formed our study group. A total of 210 age-matched men who had urologic disease other than ED served as control group. An experienced cardiologist who was blind to the primary diagnosis evaluated the ECGs in the entire group. The results were reported as either normal or abnormal according to the presence or absence of an abnormality suggestive for cardiovascular disease. RESULTS: The mean age of the study and control groups was 58 years (range for the study group 28-82 years and for the control group 28-80 years). Abnormal ECG rates among patients with ED and control subjects were comparable. The incidences of ECG abnormalities in the study and control groups were 21.1% and 17.1%, respectively (P = 0,298). No ECG abnormality was detected in males younger than 40 in either group. CONCLUSION: Middle-aged or older men with ED may carry potential risk for cardiovascular diseases in the absence of cardiovascular symptoms. However, patients with organic ED are not under increased risk for ECG abnormalities.

OBJECTIVE: In developed nations, surgery, especially gynecologic procedures, is the major cause of vesicovaginal fistulas (VVFs). We retrospectively evaluated our treatment modalities for VVF repair caused by a gynecologic surgery, and discussed the reasons of selecting certain surgical techniques and their outcomes. MATERIALS AND METHODS: We compared the surgical procedure preferences of surgeons and their results with patient and surgeon characteristics for the management of VVFs after an inciting gynecologic surgery in Süleyman Demirel University Hospital, Isparta over a 10-year period. The surgical procedures were undertaken in departments of urology and obstetrics and gynecology. RESULTS: Abdominal repair was chosen for 65%, vaginal repair for 25%, and laparoscopic repair for 10% of patients. For the 75% of the patients that urologists operated, they chose the abdominal route. The mean parity number of patients who underwent abdominal repair was lower than that for vaginal repairs (p<0.05). For the patients managed with the vaginal route, 20% had a Martius flap, and 80% had a simple excision and repair. For patients operated via the abdominal route, 18% needed omental flap; no tissue interposition was used for the rest. The mean hospitalization time was less in patients managed with transvaginal repair (3.4 days) compared with transabdominal repair (9.2 days) (p<0.05). CONCLUSION: The choice of repair method depends on surgeon's training (gynecology vs. urology). The vaginal route should be the first choice because it does not compromise the success rate and the mean hospitalization time is less. For the transvaginal approach, access to the lesion is the most important factor for the success of the procedure. No flap is needed for tissues that appear well vascularized.
RESUMEN
AIM: To examine the effects of melatonin treatment on lipid peroxidation (LPO) and the activities of antioxidant enzymes in the testicular tissue of streptozotocin (STZ)-induced diabetic rats. METHODS: Twenty-six male rats were randomly divided into three groups as follows: group I, control, non-diabetic rats (n = 9); group II, STZ-induced, untreated diabetic rats (n = 8); group III, STZ-induced, melatonin-treated (dose of 10 mg/kg . day) diabetic rats (n = 9). Following 8-week melatonin treatment, all rats were anaesthetized and then were killed to remove testes from the scrotum. RESULTS: As compared to group I, in rat testicular tissues of group II , increased levels of malondialdehyde (MDA) (P < 0.01) and superoxide dismutase (SOD) (P < 0.01) as well as decreased levels of catalase (CAT) (P < 0.01) and glutathione peroxidase (GSH-Px) (P > 0.05) were found. In contrast, as compared to group II, in rat testicular tissues of group III, levels of MDA decreased (but this decrease was not significant, P > 0.05) and SOD (P < 0.01) as well as CAT (P < 0.05) increased. GSH-Px was not influenced by any of the treatment. Melatonin did not significantly affect the elevated glucose concentration of diabetic group. At the end of the study, there was no significant difference between the melatonin-treated group and the untreated group by means of body and testicular weight. CONCLUSION: Diabetes mellitus increases oxidative stress and melatonin inhibits lipid peroxidation and might regulate the activities of antioxidant enzymes of diabetic rat testes.

Vesicocutaneous fistulas are very rare pathologies in the urinary tract. We present the second case of a vesicocutaneus fistula after cesarean section, and discuss strategies for prevention, diagnosis, and treatment of this exceptional complication. A woman with a vesicocutaneous fistula after cesarean delivery was admitted and diagnostic tests including fluoroscopy, magnetic resonance imaging (MRI), and reconstructed MRI revealed the fistula tract and an urachal anomaly. The patient was treated through excision of the fistula tract. Laparotomy should be performed carefully, and the surgeon should be aware of the urachus. Inadvertent trauma to the urachus during laparotomy might cause serious unexpected complications. Possible etiologic factors for vesicocutaneous fistulae, prevention, and treatment methods are discussed.
RESUMEN
PURPOSE: To investigate the chromosomal changes in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: A total of 54 patients diagnosed with clinical BPH underwent transurethral prostate resection to address their primary urological problem. All patients were evaluated by use of a comprehensive medical history and rectal digital examination. The preoperative evaluation also included serum prostate-specific antigen (PSA) measurement and ultrasonographic measurement of prostate volume. Prostate cancer was detected in one patient, who was then excluded from the study. We performed conventional cytogenetic analyses of short-term cultures of 53 peripheral blood samples obtained from the BPH patients. RESULTS: The mean (±standard deviation) age of the 53 patients was 67.8±9.4 years. The mean PSA value of the patients was 5.8±7.0 ng/mL. The mean prostate volume was 53.6±22.9 mL. Chromosomal abnormalities were noted in 5 of the 53 cases (9.4%). Loss of the Y chromosome was the most frequent chromosomal abnormality and was observed in three patients (5.7%). There was no statistically significant relationship among age, PSA, prostate volume, and chromosomal changes. CONCLUSIONS: Loss of the Y chromosome was the main chromosomal abnormality found in our study. However, this coexistence did not reach a significant level. Our study concluded that loss of the Y chromosome cannot be considered relevant for the diagnosis of BPH as it is for prostate cancer. Because BPH usually occurs in aging men, loss of the Y chromosome in BPH patients may instead be related to the aging process.

OBJECTIVE: One of the factors that determines the treatment success of shockwave lithotripsy (SWL) is the frequency of the shockwaves during the procedure. This study compared the efficacy and pain perception of shockwave frequencies at 30 versus 60 shocks/min for kidney stones. MATERIALS AND METHODS: From August 2013 to May 2015, 160 patients with solitary, radiopaque kidney stones were randomized to SWL at 30 shocks/min (group 1) or 60 shocks/min (group 2), with 80 patients in each group. The primary outcome measure was success rate at 3 months after the last SWL session. The secondary outcome measure was pain perception during the procedures. RESULTS: Of the 160 randomized patients, data for a total of 148 patients (74 patients in group 1 and 74 patients in group 2) were analyzed, after the exclusion of the patients lost to follow-up or who required secondary intervention within 3 months. There was no statistically significant difference between the two groups in terms of the success rate at 3 months (68.9% vs 71.6%, p = .719). However, the mean visual analogue scale scores of all the sessions were significantly higher in group 1 than in group 2 (5.83 vs 4.06, p < .05). Stone location, especially the lower calyceal location, was the only significant negative predictor for success according to multivariate logistic regression analysis. CONCLUSIONS: The success rate was similar between these two frequencies. However, pain perception was significantly higher at 30 than at 60 shocks/min.

PURPOSE: To investigate the effects of thermochemotherapy with mitomycin C (MMC) on normal rabbit bladder urothelium and to compare it with standard intravesical MMC and hyperthermia with normal saline. METHODS: Twenty-four male New Zealand rabbits, with a mean weight of 2.7 kg (in weight of 2.14.3 kg), were divided into three groups, each containing eight rabbits. Thermotherapy with only normal saline was performed in the first group, standard intravesical MMC was performed in the second group, and thermotherapy with MMC was performed in the last group. A week after the primary procedure, total cystectomy was performed and tissue samples were evaluated. RESULTS: The presence of epithelial vacuolar degeneration (p = 0.001), epithelial hyperplasia (p = 0.000), subepithelial fibrosis (p = 0.001) and hemorrhagic areas in the connective tissue (p = 0.002) was observed statistically significantly higher in the standard MMC group than in thermotherapy with normal saline group. There was almost a significant difference among standard MMC and normal saline group in terms of vascular congestion in the connective tissue (p = 0.08). Presence of epithelial vacuolar degeneration (p = 0.002), epithelial hyperplasia (p = 0.002), subepithelial fibrosis (p = 0.030), hemorrhagic areas (p = 0.011) and vascular congestion (p = 0.36) in the connective tissue was observed statistically significantly higher in the thermochemotherapy with MMC group than in standard intravesical MMC group. Polymorphonuclear cell infiltration was not considerable in any of the groups, and there was no significant difference between each groups (p = 0.140). CONCLUSION: Administration of intravesical MMC causes a toxic effect on the normal urothelium of the bladder rather than an inflammatory reaction. Heating MMC significantly increased this effect.

A 45-year-old woman applied to our clinic with complaints of recurrent dysuria and excretion of some plastic pieces with her urine for the last one year. When we examined the plastic pieces we recognized that they were some double J fragments. The kidney ureter bladder radiography (KUB) demonstrated about 2-3 cm of stent fragments at the left ureter, left kidney and bladder. There was a 3 cm of bladder opacity encircling the fragment at the bladder. The bladder stone refracted and the stent fragment was taken out. Then ureterorenoscopy performed and the pieces at the ureter were taken out.

A 42-year-old man presented with right lower quadrant abdominal pain and dysuria. The bladder was displaced to the right side of the pelvis in excretory urography. Abdominal CT revealed a mass in right adrenal gland, measuring 8 cm in diameter. There was also a cystic mass; filling left half of the bony pelvis and displacing bladder to the right, measuring 14.5 x 10, 5 x 7 cm. The patient underwent right adrenalectomy and pelvic mass excision. Pathologic examination showed that the adrenal mass was pheochromocytoma and pelvic mass was dermoid cyst. This case is the first one in literature that an intrapelvic dermoid cyst is not derived from an organ coexists with pheochromocytoma.
