RESUMEN

INTRODUCTION: Herein, we analyzed the histopathological, oncological and functional outcomes of testis-sparing surgery (TSS) in patients with distinct risk for testicular cancer. METHODS: This is a multicenter retrospective study on consecutive patients who underwent TSS. Patients were categorized in high- or low-risk testicular germ cell tumor (TGCT) according to the presence/absence of features compatible with testicular dysgenesis syndrome. Histology was categorized per size and risk groups. RESULTS: TSS was performed in 83 patients (86 tumors) of them, 27 in the high-risk group. Fifty-nine patients had a non-tumoral contralateral testis present. Sixty masses and 26 masses were benign and TGCTs, respectively. No statistical differences were observed in mean age (30.9 ± 10.32 years), pathological tumor size (14.67 ± 6.7 mm) between risk groups or between benign and malignant tumors (p = 0.608). When categorized per risk groups, 22 (73.3%) and 4 (7.1%) of the TSS specimens were malignant in the high- and low-risk patient groups, respectively. Univariate analysis showed that the only independent variable significantly related to malignant outcome was previous history of TGCT. During a mean follow-up of 25.5 ± 22.7 months, no patient developed systemic disease. Local recurrence was detected in 5 patients and received radical orchiectomy. Postoperative testosterone levels remained normal in 88% of those patients with normal preoperative level. No erectile dysfunction was reported in patients with benign lesions. CONCLUSION: TSS is a safe and feasible approach with adequate cancer control, and preservation of sexual function is possible in 2/3 of patients harboring malignancy. Incidence of TGCT varies extremely between patients at high and low risk for TGCT requiring a careful consideration and counseling.

RESUMEN

BACKGROUND: The functional and oncological outcomes of zero ischemia robotic partial nephrectomy (RPN) procedures were evaluated. METHODS: A total of 56 patients underwent zero ischemia RPN transperitoneally, and their data were collected prospectively. Radius, exo/endophytic, nearness, anterior/posterior, location (R.E.N.A.L.) nephrometry, and PADUA scores were calculated. Patient and tumor characteristics were evaluated. Intra- and perioperative (0-30 days) complications were evaluated by Clavien classification. The change in serum creatinine, and estimated glomerular filtration rates (eGFR) were evaluated during preoperative, immediate postoperative periods, and at postoperative 6th months. RESULTS: The mean age of the patients was 52.2 ± 8.1 (27-75) years. R.E.N.A.L. nephrometry and PADUA scores were 6.1 ± 1.3 and 7.3 ± 1.0, respectively. The duration of surgery was 108.4 ± 18.2 min and estimated blood loss was 166.2 ± 124.7 mL. There were no intraoperative complications in any of the patients. Clavien Grade 1 and 3 complications were seen in 2 patients in the perioperative period. In the perioperative period (1-30 days), one patient required blood transfusion and angiographic intervention due to postoperative bleeding (Clavien Grade 3), and one patient required hospitalisation due to prolonged subileus (Clavien Grade 1) that resolved conservatively. The radiological and pathological tumor sizes were 3.1 ± 1.1 cm and 2.8 ± 1.4 cm, respectively. The surgical margins were positive in two patients with tumour sizes of 1.5 and 4 cm. Neither local recurrence nor distant metastasis was detected, during 33.6 ± 12.3 (3-76) months. There were no statistically significant differences between preoperative eGFR and serum creatinine levels, compared with those of immediate postoperative and postoperative 6th month periods. DISCUSSION: Zero ischemia RPN is a safe and applicable method with acceptable oncological and functional outcomes in small renal tumors and even in selected larger renal tumors.

RESUMEN

OBJECTIVE: After radical prostatectomy, prostate-specific antigen(PSA) value measuring ≥0.1 ng/mL is defined as persistent PSA(pPSA) and in many studies, it was found to be associated with aggressive disease and poor prognosis. Our aim in this study is to point out the pathological and clinical factors affecting pPSA among the patients who underwent robot-assisted radical prostatectomy(RARP) in an experienced academic centre and to make a useful risk grouping algorithm that can predict pPSA value based on operative data. METHODS: We examined records of 1273 patients who underwent RARP retrospectively. Preoperative, operative and postoperative data were collected. Based on the PSA values (ng/mL) measured after 4-to-8 weeks of RARP, patients were divided into two groups as pPSA group (Group1)(n = 97) with PSA values ≥0.1 ng/mL and undetectable PSA group (Group2)(n = 778) with PSA values <0.1 ng/mL. Later on, Group1 was further divided into Group1a (PSA:0.1-0.2 ng/mL) and Group 1b (PSA≥0.2 ng/mL) to evaluate biochemical recurrence(BCR). RESULTS: Multivariate logistic regression analyses of the collected data revealed that preoperative PSA≥20 ng/mL, operation time, a postoperative international society of urological pathology (ISUP) grade of ≥4, pT 3-4 and pN were independently associated with pPSA. Based on these results, a risk grouping algorithm predicting pPSA was developed. By looking at the risk grouping algorithm pPSA was found in 98.9% of the cases with a preoperative PSA value of ≥20 ng/mL, an operation time of 150 min, a postoperative ISUP grade of 4-5, a positive lymphovascular invasion (LVI) status, pT3-T4, and pN+; while pPSA was found in 25.5% of the cases with a preoperative PSA value of <20 ng/mL, an operation time of 100 min, a postoperative ISUP grade of <4-5, a negative LVI status, pT<3-4 and pN-. The estimated BCR-free survival time was 16.3 months in Group 1a and 57.0 months in Group2 (P < .001). Adjuvant treatment ratio was 64.9% in Group1 and 7.1% in Group2 (P < .001). CONCLUSION: For the patients who underwent RARP, factors associated with aggressive disease can predict the PSA persistence. To plan our treatment modalities accurately, an applicable risk grouping algorithm in daily practice would be useful.

RESUMEN

BACKGROUND: Although there are no sufficient data on association between oxidative stress and erectile dysfunction (ED), numerous studies have reported that imbalance between the formation of reactive oxygen species and body's antioxidant defenses may play a role in the pathogenesis of ED. AIM: The aim of this study was to determine and compare the oxidant and antioxidant status in patients with ED and healthy controls with a novel automated assay for thiol/disulphide homeostasis test. METHODS: Our study included 123 patients with ED and 90 healthy individuals. ED was evaluated by asking questions 1-5 and 15 of the International Index of Erectile Function form. In this study, we used Erel and Neselioglu's thiol/disulfide homeostasis test, which is one of the novel methods that can measure both variables of the oxidative/antioxidative balance individually and collectively. OUTCOMES: This method measured serum antioxidant (total thiol [toSH], native thiol [SH]) and oxidant (disulfide [SS]) levels. The statistical comparisons were performed between patients with ED (ED+ group) and without ED (ED- group) first and then within the ED+ group. After toSH, SH, and SS levels were determined; SS/toSH%, SS/SH%, and SH/toSH% levels were analyzed separately and compared statistically. RESULTS: We found a significant difference between ED- and ED+ groups in terms of toSH, SH, SS/toSH%, and SS/SH% ratios. SS parameters were increased in patients with ED, but there was no significant difference in terms of SS and SH/toSH% values. CLINICAL IMPLICATIONS: Clarification of the factors involved in the etiology of ED such as oxidative/antioxidative balance may open new grounds in the early diagnosis and treatment of the disease. STRENGTHS & LIMITATIONS: It is a prospective, randomized clinical study with the use of a novel, reliable, and fully automated technique. The limitations of the study are use of a subjective tool such as the International Index of Erectile Function, obtaining blood samples from the peripheral vein instead of penile cavernosal tissue, and relatively small sample size. CONCLUSION: The results of this study showed that thiol/disulfide homeostasis is altered in ED, and this imbalance may be a factor in its pathophysiology. We determined that as ED gets more severe, toSH and SH parameters decrease, whereas SS parameter increases. Micoogullari U, Karatas OF, Kisa E, et al.

RESUMEN

In this study, we compared the weight of the prostate specimen removed after robotic radical prostatectomy with the prostate weight measured pre-operatively by four different imaging modalities. Pre-operative prostate weight before robotic radical prostatectomy was measured by Transabdominal Ultrasonography (TAUS), Transrectal Ultrasonography (TRUS), Abdominal Tomography (CT) and MultiparametricProstate Magnetic Resonance imaging (mpMRI). Of the 170 patients enrolled in the study, the mean age was 65.2 ± 7.08 (46-84) years and mean prostate-specific antigen (PSA) 9.6 ± 7.7 (1.8-50). The mean post-operative actual prostate weight was 63.1 ± 30 gr. The mean pre-operative prostate volumes measured by TAUS, TRUS, CT and MPMRI were 64.5 ± 28.5, 49.1 ± 30.6, 54.5 ± 30.5 and 68.7 ± 31.7 ml, respectively (p < .001). Post-operative actual prostate weight correlated with prostate weight measured by TAUS, TRUS, CT and mpMRI (r coefficient 0.776, 0.802, 0.768 and 0.825 respectively). The best of these was mpMRI. Although prostate weight measured by different imaging methods has a high correlation to predict actual prostate weight, actual prostate weight is best predicted by measurements with mpMRI. However, errors and deviations that may occur with these imaging methods should be taken into consideration.

RESUMEN

The aim of this study was to evaluate the relationship between penile colour doppler ultrasonography (PCDUS) and complete blood count parameters in patients with erectile dysfunction (ED). The data of the patients who applied to our outpatient clinic with ED (IIEF-5 score <22 or IIEF-EF score <26) between January 2007 and May 2017 were retrospectively analysed. The patients who had available PCDUS results and complete blood count (CBC) values were included in the study. Patients were divided into two groups having normal (n = 530 [68.9%]) or abnormal (n = 240 [31.1%]) PCDUS findings (group 1 versus group 2 respectively). Subsequently, group 2 was divided into three subgroups according to presence of arterial insufficiency (group 2a; n = 85 [11%]), venous insufficiency (group 2b; n = 140 [18.2%]) and both of arterial and venous insufficiency (group 2c; n = 15 [1.9%]), and the four groups were compared in terms of CBC parameters. There was no statistically significant difference between the 4 groups, and between the patients with normal and abnormal PCDUS findings in terms of CBC values. CBC values were not associated with PCDUS findings in patients with ED.

RESUMEN

PURPOSE: To evaluate the effect of corticosteroid (CS) on early postoperative pain, renal colic and total analgesic consumption after uncomplicated and unstented ureteroscopy (URS). METHODS: Data of 397 patients who underwent URS and stone fragmentation for symptomatic distal ureteral stone (≤ 15 mm) were retrospectively evaluated. After exclusion, 72 patients who received methylprednisolone (Group I) after non-stenting uncomplicated URS were matched with another 72 patients who did not receive CS (Group II). Cases were matched 1:1 ratio and the matched-pair criteria were age, stone diameter, and duration of surgery. RESULTS: Both groups were statistically similar in terms of mean age, operative time, stone size and preoperative pain score. However, the mean postoperative pain score was statistically significantly lower in group I than group II on the day of surgery (3.3 ± 1.7 vs. 3.9 ± 1.3, p = 0.012) and postoperative day 1 (2.8 ± 1.8 vs. 3.4 ± 1.3, p = 0.02), respectively. Renal colic episode development rate (4.2 vs. 13.2%, p = 0.036), parenteral analgesic requirement rate (18.1 vs. 33.3%, p = 0.001) and total parenteral analgesic consumption per patient (18 vs. 36mg, p = 0.009) were statistically lower in group I than group II on the day of surgery; however, there were no statistically significant differences on postoperative day 1. There were no statistically significant differences between groups in terms of ureteral stenting requirement and late unplanned urgent room visit rates. CONCLUSIONS: Corticosteroid after uncomplicated URS can be offered to reduce early postoperative pain, renal colic episode and total analgesic consumption.

RESUMEN

To evaluate the efficiency of percutaneous nephrolithotomy using adult-type instruments in children with kidney stones. Between September 2004 and October 2009, 18 children (19 renal units) underwent percutaneous nephrolithotomy using adult-type instruments. Following percutaneous access under fluoroscopy, 20-30F tract dilatation was performed (1,92,427F), and lithotripters were used. Postoperatively, kidney-ureter-bladder X-ray and antegrade pyelography were performed to evaluate residual stones and contrast passage to the bladder. 8 boys and 10 girls with a mean age of 9.8 ± 4.56 years were evaluated. Mean stone burden was 338 ± 196.21 mm². Stones were located in the left and right kidneys in 16 (84.2%) and 3 (16.8%) patients, respectively. Horse-shoe kidney was present in one patient. Mean operation (including cystoscopy) and fluoroscopy times were 106 ± 49.60 and 5.2 ± 2.14 min, respectively. Postoperatively, 10(52.6%) patients were stone free and 4 (21.1%) patients had clinically insignificant stones. Saline extravasation developed in three patients and surgery was aborted in one patient. Stone fragments migrated into the ureter in two patients and managed by additional endourological interventions. Nephrostomy catheters were kept for a mean of 2.6 ± 1.12 days. Four patients required blood transfusion due to bleeding. Postoperative fever of <39°C developed in five patients and >39°C in one patient. Mean hospitalization time was 5.3 ± 3.12 days. Overall, 73.7% of our patients were stone free, including patients with clinically insignificant stones. Particularly in children with a high-stone burden, the use of adult-type instruments might have a positive impact on stone-free rate, operation time and fluoroscopy time without increasing the complication rate.

RESUMEN

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.

RESUMEN

BACKGROUND AND OBJECTIVES: Robot-assisted laparoscopic radical prostatectomy (RALRP) is successfully being performed for treating prostate cancer (PCa). However, instrumentation failure associated with robotic procedures represents a unique new problem. METHODS: We report the successful completion of RALRP in spite of a disassembled hand piece spring during the procedure. A PubMed/Medline search was made concerning robotic malfunction and robot-assisted laparoscopic radical prostatectomy to discuss our experience. RESULTS: We performed RALRP in a 60-year-old male patient with localized PCa. During the procedure, the spring of the hand piece disassembled, and we were not able to reassemble it. We completed the procedure successfully however without fixing the disassembled hand piece spring. We were able to grasp tissue and needles when we brought our fingers together. The only movement we needed to do was to move fingers apart to release tissue or needles caught by robotic instrument. CONCLUSION: Although malfunction risk related to the da Vinci Surgical System seems to be very low, it might still occur. Sometimes, simple maneuvers may compensate for the failed function as occurred in our case. However, patients should be informed before the operation about the possibility of converting their procedure to laparoscopic or open due to robotic malfunction.

RESUMEN

OBJECTIVES: Ureteric duplication is a rarely seen malformation of the urinary tract more commonly seen in females. MATERIALS AND METHODS: We report 2 cases of robot-assisted laparoscopic radical cystoprostatectomy (RALRCP) with bilateral extended pelvic lymph node dissection and intracorporeal Studer pouch formation in patients with duplicated right ureters. RESULTS: Two male patients (53 and 68 years old) underwent transurethral resection of a bladder tumor that revealed high-grade muscle invasive transitional cell carcinoma, with no metastases. We performed RALRCP and intracorporeal Studer pouch formation. A duplicated right ureter was observed during the procedures in both patients. Left ureter distal segment was spatulated 2cm long and anastomosed using running 4/0 Vicryl to the right ureter at its bifurcation where it forms a single lumen without spatulation. All 3 ureters were catheterized individually. A Wallace type uretero-ileal anastomosis was performed between the ureters and the proximal part of the Studer pouch chimney. Although ureteric frozen section analysis suggested ureteric carcinoma in situ in patient 1, postoperative pathologic evaluation was normal. Frozen section and final postoperative pathologic evaluations were normal in patient 2. CONCLUSIONS: Duplicated ureters might be underdiagnosed on CT. The presence of a duplicated ureter is not a contraindication to RALRCP and intracorporeal Studer pouch formation. The da Vinci-S surgical robot is very safe for performing this complicated procedure. Frozen section analysis of ureters during radical cystectomy for bladder cancer might not reliably diagnose the pathologic condition and might overestimate the disease in the ureters.

RESUMEN

Retrograde intrarenal surgery (RIRS) is one of the minimally invasive main treatment modalities in renal stone disease. There are many factors which affect stone-free rate (SFR). Our study was based on the hypothesis that higher renal parenchymal thickness (RPT) which may include higher average number of nephrons provides better diuresis. We investigated the efficacy of RPT on success of RIRS. This study is a single-centered prospective surgical cohort study. A total of 383 patients were analyzed. Regularly followed 304 patients with unilateral kidney stone at single pole or renal pelvis and who underwent single-session RIRS were included in the final analysis, and the patients' preoperative and postoperative 1st and 3rd months' data were evaluated. RPT was measured on the non-contrast computed tomography (CT) images. ROC analysis was performed to estimate the cutoff value of RPT for SFR. Univariate and multivariate logistic regression analyses were used to model the relationship between RPT and SFR after RIRS. ROC analysis revealed the best cutoff value of the RPT for predicting residual stone as 19 mm for both the 1st and 3rd month visits with Youden indexes of 0.397 and 0.406, respectively. To the best of our knowledge, this is the first study which evaluated the effect of RPT on the efficacy of RIRS. RPT measurement is a cost-effective method that can be easily performed on routinely applied non-contrast CT and may have predictive value for the surgical success in patients with nephrolithiasis.

RESUMEN

BACKGROUND: It was aimed to compare open versus robotic-assisted radical cystectomy (RARC) with intracorporeal ileal conduit (ICIC), versus RARC with extracorporeal ileal conduit (ECIC) formation for bladder cancer. MATERIALS AND METHODS: Open, RARC-ECIC and RARC-ICIC groups were compared in terms of patient demographics, operative and postoperative parameters, pathological parameters, complications and functional outcomes. RESULTS: Mean operative times were lower in the RARC-ECIC group (p = 0.004). Mean estimated blood loss was significantly lower (p < 0.01) in the robotic groups. The blood transfusion was lower in RARC-ICIC groups (p < 0.001). Rates of stage pT3-4 disease were the highest in the RARC-ICIC group (p = 0.004). LOS was significantly shorter in the RARC-ICIC group (p = 0.01). Numbers of Clavien 3-5 complications were lower in the robotic groups (p = 0.012). CONCLUSIONS: RARC and ICIC is a complex procedure involving an increased operation time but with the advantages of lower estimated blood loss, transfusion rates, complications and hospital stays compared with open surgery.

RESUMEN

INTRODUCTION: In addition to "lifelong" and "acquired" premature ejaculation (PE) syndromes, two more PE syndromes have recently been proposed: "Natural variable PE" and "premature-like ejaculatory dysfunction." AIM: The purpose of this study was to analyze the prevalence of the four PE syndromes among patients who were admitted to a urology outpatient clinic with the complaint of ejaculating prematurely. METHODS: Between July 2008 and March 2009, patients admitted to a urology outpatient clinic with a self-reported complaint of PE were enrolled into the study. After taking a careful medical and sexual history, patients were classified as "lifelong,""acquired,""natural variable," PE or "premature-like ejaculatory dysfunction." MAIN OUTCOME MEASURES: In addition to medical and sexual history, self-estimated intravaginal ejaculatory latency times (IELTs) of patients were used in the classification of patients. RESULTS: A total of 261 potent men with a mean age of 36.39 +/- 10.45 years (range 20-70) were recruited into the study. The majority of the men was diagnosed as having lifelong PE (62.5%); the remaining men were diagnosed as having acquired (16.1%), natural variable PE (14.5%), or premature-like ejaculatory disorder (6.9%). The mean age of patients with acquired PE was significantly higher than the other groups (P = 0.001). No significant difference was observed for educational status or income level of patients in the different PE groups (P = 0.983 and P = 0.151, respectively). The mean self-estimated IELT for all subjects was 65.16 +/- 83.75 seconds (2-420 seconds). Patients with lifelong PE had significantly lower mean self-reported IELT, whereas the patients with premature-like ejaculatory dysfunction had the highest mean IELT (P = 0.001): (i) life-long PE: 20.47 +/- 28.90 seconds (2-120 seconds); (ii) aquired PE: 57.91 +/- 38.72 seconds (90-180 seconds); (iii) natural variable PE: 144.17 +/- 22.47 seconds (120-180 seconds); and (iv) premature-like ejaculatory dysfunction: 286.67 +/- 69.96 seconds (180-420 seconds). CONCLUSIONS: The majority of patients who seek treatment for the complaint of ejaculating prematurely describes lifelong PE. Further population-based studies are required to determine the actual prevalences of these four PE syndromes.

RESUMEN

PURPOSE: To compare the patients who underwent robot assisted radical cystectomy (RARC) and extended pelvic lymph node dissection (EPLND) and whose pathology result was reported as micropapillary variant (MV), plasmacytoid variant (PV) and pure urothelial carcinoma (PUC). MATERIALS AND METHODS: The data of 133 patients who underwent RARC and EPLND with the postoperative pathology results reported as MV, PV and PUC were analyzed. According to the postoperative pathology results, patients were divided into two groups in initial analyses as variant pathologies group (n=14) and PUC group (n=119). In secondary analyses, patients were divided into three groups as MV group (n=7), PV group (n=7) and PUC group (n=119). The operative data, oncologic outcomes and complications were compared between the groups. RESULTS: Median operation time and estimated blood loss were significantly increased in variant pathologies group (P <0.001 and P = .001, respectively). The postoperative pathological T stage, positive surgical margin rate and lymph node involvement were also significantly increased in variant pathologies (P = .001, P = 0.004, P <0.001, respectively). Kaplan-Meier analysis revealed significant decrease in OS and CSS times in PV group compared to PUC group (P = .048 and P = .016, respectively). CONCLUSION: MV and PV are rarely seen variant pathologies with higher pathological T stages. RARC is a minimally invasive surgical technique that can be performed successfully by an experienced surgical team with low morbidity rates and similar oncological results, even in challenging cases.

RESUMEN

PURPOSE: In this study, we retrospectively reviewed the penile color Doppler ultrasound (PCDU) scans of the patients who had admitted to our clinic with erectile dysfunction and aimed to evaluate the contribution of penile Doppler scan results to the clinical decisions. MATERIAL-METHOD: The data of patients admitted to our outpatient clinic with complaints of erectile dysfunction (IIEF-5 score<22 or IIEF-EF score<26) between January 2005 and January 2018 were retrospectively evaluated. Patients whose testosterone level is lower than 280ng/ml or who had undergone radical prostatectomy were excluded from the analysis. RESULTS: Three thousand ninety patients were included in the study. The mean age of our patients was 55.05±13.05 years. In total, 2139 (69%) patients had normal PCDU findings, 351 (11%) patients had arterial insufficiency, 531 (17%) patients had venous insufficiency, and 69 (2%) patients had arterial insufficiency with concurrent venous leakage. When the patients were divided into 2 groups ≤40 years (Group 1) old and >40 years (Group 2) old; normal PCDU findings were found in 432 patients (84%) of the Group 1 patients and normal PCDU findings in 1707 (66%) patients of the Group 2 patients (p<0.0001). There were arterial insufficiency findings in 24 (4.7%) and 327 (12.7%) patients of the Group 1 and 2, respectively (p=0.002). CONCLUSION: The etiology is psychogenic in the majority of patients who present with ED complaints to the urology clinic. With age, the prevalence of psychogenic ED is decreasing but still more than organic.

RESUMEN

OBJECTIVE: We present our experience in performing testis sparing surgery (TSS) to treat sequential bilateral testicular tumors. MATERIAL AND METHODS: We performed TSS on two patients with bilateral sequential testicular tumors. RESULTS: A 43-year-old patient (Case 1) and a 33-year-old patient (Case 2) had previous inguinal orchiectomy for seminoma. The patients were diagnosed with secondary testicular tumors in the contralateral testes on follow up. They were treated with TSS after frozen section analysis of the peritumoral testicular tissue. Pathologic evaluation of the removed tumors revealed immature teratoma and Leydig cell tumor. Both patients are disease free without local recurrence and do not have erectile dysfunction, and thus do not need androgen replacement therapy after a follow up of 6 months and 44 months, respectively. CONCLUSIONS: TSS after frozen section analysis appears to be a safe and feasible procedure that, in carefully selected cases, offers adequate cancer control, preserves sexual function, and provides psychological benefits.

RESUMEN

Oxidative stress has been considered as one of the possible mechanisms of ischemia/ reperfusion (I/R) injury in the kidney. The aim of this study was to analyze the possible protective effect of dietary ginger (Zingiber officinals Rosc), a free radical scavenger, on renal I/R injury in rats. The protective effect of ginger against the damage inflicted by reactive oxygen species (ROS) during renal I/R was investigated in Wistar albino rats using histopathological and biochemical parameters. Thirty rats were randomly divided into five experimental groups (i.e., control, sham-operated, ginger, I/R, and I/R + ginger groups, n = 6 each). The ginger and I/R + ginger groups were fed on the test diet containing 5% ginger. The rats were subjected to bilateral renal ischemia followed by reperfusion in I/R and I/R + ginger groups. At the end of the reperfusion period, rats were sacrificed, and kidney function tests, serum and tissue oxidants and antioxidants, and renal morphology were evaluated. Serum urea, creatinine, and cystatin C (CYC) levels were significantly elevated in the ischemia group, but these levels remained unchanged in the ginger + I/R group compared to the I/R group. Reduction of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) enzyme activity was significantly improved by the treatment with ginger compared to I/R group. Administration of ginger resulted in significant reduction levels of tissue malondialdehyde (MDA), NO, protein carbonyl contents (PCC) in the ginger + I/R group compared with the I/R group. Ginger supplementation in the diet before I/R injury resulted in higher total antioxidant capacity (TAC) and lower total oxidant status (TOS) levels than I/R group. The ginger supplemented diet prior to I/R process demonstrated marked reduction of the histological features of renal injury. The findings imply that ROS play a causal role in I/R-induced renal injury, and ginger exerts renoprotective effects probably by the radical scavenging and antioxidant activities.
