Parapelvic Renal Cyst Treatment with Flexible Ureteroscopy: Single Centre Experience.

BACKGROUND: This study aimed to assess the feasibility, safety, and efficacy of an endoscopic parapelvic renal cyst (PRC) incision using flexible ureterorenoscopy (fURS). MATERIAL AND METHODS: We retrospectively reviewed data concerning 16 patients in whom PRC incisions had been performed using fURS between January 2016 and January 2022. Two patients were excluded from the study owing to a lack of follow-up information. The cysts of all the patients were evaluated preoperatively by computed tomography. The patients' age, gender, cyst size, presenting symptoms, postoperative complications, and pre- and post-treatment visual analogue scale (VAS) scores were evaluated. Surgical success was defined as a reduction of more than half of the cyst size in the sixth postoperative month. RESULTS: A total of 14 patients were included in this study. The patients' mean age was 52.6 ± 8.8 years, and the mean cyst size was 69.1 ± 15.5 mm. Twelve (85.7%) patients presented with flank pain. Clavien-Dindo grade 1 complications were observed in two patients (14.3%), and grade 2 complications were observed in one (7.1%). The median VAS scores were significantly lower after treatment than before in patients who presented with flank pain (2 (1-2.8) vs 8 (7-8), respectively; p = 0.002). Surgical success rate was detected in 11 patients (78.6%) six months after the treatment. CONCLUSIONS: Endoscopic incision of the PRC is a feasible treatment modality with high success rates and low complication rates. However, multicentre studies with larger populations and longer follow-ups are needed to evaluate the lasting effects.

Comparison of Transrectal Ultrasonography-Guided Prostate Biopsies Analgesia's; Rectal Lidocaine Gel Versus Sandwich Anesthesia (Transurethral Plus Transrectal Lidocaine Gel Administration): A Double-Blind, Randomized, Controlled and Prospective Study.

Objectives: We aimed to evaluate the effectiveness of the additive transurethral anesthetic agent to transrectal anesthetic agent. Methods: Transrectal ultrasound-guided 12 core prostate biopsy planned, 237 patients included in our study. The patients randomly divided into two groups. Group 1 (n=113): Only transrectal 2% lidocaine, Group 2 (n=124): Transrectal + Transurethral(Sandwiches) lidocaine gel given to the patients 10 min before the procedure as anesthesia. Immediately after the biopsy, the patient questioned about the level of pain he felt during the needle entry. The evaluation measured by the VAS score. Immediately after biopsy satisfaction rate with the procedure and if rebiopsy was required, acceptance was scored between 1 and 4. The two groups compared statistically. Results: The mean VAS score of Group 1 and Group 2 was 4.88±1.89 and 3.77±1.83, respectively. The pain level of Group 2 was lower than Group 1' pain level. The difference between the two groups was considered statistically significant (p<0.001). The patient satisfaction rates of Group 1 and Group 2 found to be 2.45±0.71 and 2.78±0.66, and the acceptance rate of rebiopsy was 2.81±0.69 and 3.02±0.51, respectively. The patient satisfaction rate and acceptance rate of the rebiopsy of Group 2 were higher than Group 1. Patient satisfaction level (p<0.001) and rebiopsy acceptance rate (p=0.014) between the two groups found to be statistically significant. Conclusion: In the TRUS-guided prostate biopsies, sandwich anesthesia is a cheap, convenient, tolerable, and effective method.

Sexual intercourse before exercise has a detrimental effect on lower extremity muscle strength in men.

INTRODUCTION: The question of whether sexual intercourse can harm athletic performance is a long-debated topic since first sport competitions were invented. Therefore, due to the lack of solid evidence, we aimed to evaluate the effects of sexual intercourse on muscle training performance. MATERIALS AND METHODS: Physically and sexually active, 50 men (age=29.3±1.14 years) were enrolled in the study. Participants completed three weight training sessions and all sessions were at the same time of the day. The maximum weight was adjusted in the first session. In the second and third sessions, they performed five repetitions of the squat with their maximum weight for each set with a total of five sets after participating in and abstaining from sexual intercourse the night before, respectively. The duration of sexual intercourse was measured with a stopwatch. RESULTS: The mean duration of sex was measured to be 13.8±3.61 min. Furthermore, the mean lifted weight before sex was calculated to be 109.4±11.41 kg and the mean lifted weight after sex was calculated to be 107±11.05 kg. According to obtained data, sexual intercourse has a significant detrimental effect on maximum weight in squat training (p=0001). CONCLUSION: Results demonstrate that sexual intercourse within 24 hours before exercise have detrimental effect on lower extremity muscle force, which suggests that restricting sexual activity before a short-term activity may be necessary.

Failure of ureteral access sheath insertion in primary flexible ureteroscopy for renal stones: is there any relation with inflammation?

PURPOSE: To investigate the relationship between failure to insert a ureteral access sheath (UAS) with inflammation and other clinical parameters in patients treated with flexible ureteroscopy for renal stones. METHODS: This study included patients who underwent flexible ureteroscopy for the treatment of renal stones in our centre between 2015 and 2020. Patients who underwent any surgical procedure on the ipsilateral ureter and had a history of spontaneous stone passage were excluded. Patients were divided into two groups based on UAS insertion success (group 1) or failure (group 2). Both groups were compared with a view to clinical characteristics, preoperative neutrophil, lymphocyte, monocyte and platelet counts and ratios of these counts, all being considered inflammatory markers. A multivariate logistic regression analysis was performed to determine the independent variables affecting UAS insertion success. RESULTS: There were 113 (59.1%) patients in group 1, while group 2 consisted of 78 (40.9%) patients. The rates of male gender, coronary artery disease and preoperative ipsilateral hydronephrosis were significantly higher in group 2, while platelet counts and platelet-lymphocyte ratios were significantly lower. Our analysis revealed four independent predictors for UAS insertion failure: female gender (odds ratio [OR]=2.1) increased the rate of UAS insertion success, while hydronephrosis (OR=1.6), low platelet counts and PLR increased the rate of UAS insertion failure (OR=0.99, OR=0.98, respectively). CONCLUSION: Our results suggest that male gender and ipsilateral hydronephrosis are associated with increased UAS insertion failure. Although we found a relationship between relatively low platelet levels and UAS insertion failure, we think that further studies are needed to investigate this matter.

Is there a nonnegligible effect of maximum standardized uptake value in the staging and management of prostate cancer with 68Ga-prostate-specific membrane antigen positron emission tomography/computerized tomography imaging? A single-center experience.

PURPOSE: Prostate-specific membrane antigen (PSMA) positron emission tomography/computerized tomography (PET/CT) has been shown to have significant success in detecting local and distant metastases that cannot not be detected by conventional imaging. Initial staging in intermediate- and high-risk patients with prostate cancer is important for management. In addition, PSMA uptake has been shown to have a relation with grade of disease, and thus could be considered a separate noninvasive prognostic factor. In this study, we aimed to investigate the effect of PSMA PET/CT in the staging and management of prostate cancer patients as well as the relation to maximum standardized uptake value (SUVmax). METHODS: The patients referred to our department for staging prostate cancer were evaluated retrospectively (n = 65). Patients were grouped as positive for lymph node or distant metastatic disease. Primary tumor SUVmax data were compared with the prognostic factors of the disease. In addition, decisions about treatment protocol before and after PSMA PET/CT imaging were noted. RESULTS: All the patients except one were accepted as positive for primary tumor. Of the patients, 46.2% were positive for lymph node and 24.6% for distant metastases. After evaluation by PSMA PET/CT, the clinical choice of treatment changed for 43.1% of our patients. Primary tumor SUVmax and tumor-to-background SUVmax ratios were found to have a significant relation with D'Amico risk classification. We found a positive correlation between SUVmax and prostate-specific antigen, Gleason scores, and age. CONCLUSION: PSMA PET/CT images have a nonnegligible effect on staging, clinical decisions, and change in treatment protocol. SUVmax data have a positive correlation with risk classification and could be identified as a potential independent and non-invasive prognostic factor.

The impact of the pelvicalyceal anatomy characteristics on the prediction of flexible ureteroscopy outcomes.

BACKGROUND: The anatomical architecture is a prominent factor in the outcomes of flexible ureteroscopy (FURS). AIMS AND OBJECTIVES: The aim to regard the success of procedures based on Pelvicalyceal body that called Sampaio classification system. MATERIALS AND METHODS: A total of 125 FURS procedures were reviewed between December 2012 and December 2016 in our department. Seven patients were excluded from the study due to the horseshoe kidney in two cases and recurrent cystine stone configuration in five patients. The patient's renal collecting system anatomy characteristics are regarded, and they are classified into four main groups based on the mid-renal-zone anatomy assessed according to Sampaio Classification. RESULTS: Total stone-free rate (SFR) during the postoperative 1st-month evaluation was noncontrast computerized tomography 75 (63.6%). The evaluation of the SFR in all subgroup of cases based on Sampaio classification noticed easily, SFR was significantly lower in subgroup A2 (30.4%) (P = 0.00), significantly higher in subgroup B2 (P = 0.008). The comparative analysis of the operative duration defined that it was the shortest (75.3 ± 18.1 min) in Type B1 subgroup cases, and the longest (84.7 ± 25.7 min) in the Type A2 subgroup cases. Even though this duration was found to be relatively higher in Type A2 subgroup cases than the others, this difference was not statistically significant (P = 0.271). Fluoroscopy time was noted to be the shortest (11.9 ± 13.4 s) in B1 subgroup and the longest in A2 subgroup with a statistically significant different (median: 21.3 ± 30.4) (P = 0.04). While 6 (5.1%) cases had Clavien 2 and 3 (2.5%) cases, demonstrated Clavien 3a complications. CONCLUSION: The calyceal structure of the kidney affects the SFR; therefore, a detailed classification of pelvicalyceal could improve the outcomes, decrease the rate of auxiliary procedures and prevent the complications.

The role of preoperative ultrasound in the diagnosis of penile fractures and the effect of tunica defect length on postoperative functional outcomes.

PURPOSE: This study aimed to investigate the rate of tunica defect detection by postoperative penile ultrasound (US) and the effect of tunica defect length (TDL) on functional outcomes. METHODS: Forty-six patients who underwent early penile fracture surgery in our hospital between July 2010 and December 2018 were included in the study. Each diagnosis was made via history, physical examination and US. Functional outcomes were assessed at 3, 6 and 12 months postoperatively. The International Index of Erectile Function-5 (IIEF-5) score was used to assess erectile function. US detection rates for tunica defects, as well as whether the rates changed according to TDL, were also analysed. The TDL cut-off value for US detection was determined to be 11 mm using the receiver operating characteristic curve. The impact of TDL on functional outcomes was also evaluated using this cut-off value. RESULTS: The main cause of fractures in 34 patients (74%) was sexual intercourse. One patient (2.2%) had penile curvature, and 16 (34.8%) had penile nodules in the follow-ups. US had a higher detection rate in the group with TDL >11mm (94% vs 25%). IIEF-5 scores at the postoperative third month were statistically lower in patients with TDL >11mm (n = 34) compared with those with ≤11 mm (n = 12). The rate of penile nodules was found to be statistically higher in the group with TDL >11mm at the end of the 1-year follow-up period (44.1% vs 8.3%). CONCLUSIONS: US is a valuable tool for the detection of tunica defects especially with >11mm length. In addition, TDL >11 mm in penile fractures is associated with lower IIEF-5 scores in the early postoperative period and higher rates of penile nodules.

The fate of paratesticular masses: 13 years' experience in a tertiary referral centre.

OBJECTIVE: Paratesticular neoplasms exhibit different behaviours, depending on the embryological tissue of origin. Treatment modalities can depend on the differential diagnosis. The aim of this study is to present the clinical, morphological and histopathological features of patients with paratesticular masses and their follow-ups and is intended to increase awareness of the issues. METHODOLOGY: We included 31 excisions of paratesticular masses, after radiological diagnosis as paratesticular mass in our hospital between 2007-2020. Information on treatment modalities, tumour recurrence, metastasis, and survival rates were obtained from hospital archives. All patients were evaluated by taking patients' history, physical examination, scrotal ultrasound, chest radiography, and serum tumour markers. Treatment modality was selected according to intraoperative findings. Haematoxylin-eosin sections were examined, and immunohistochemical analyses were performed for smooth muscle actin, desmin, Ki67, CD34, S100, and myogenin. Ten high-power fields were counted to document Ki67 and p53 nuclear positivity rates. RESULTS: A total of 31 operations were performed with recurrence in three patients. Histomorphological and immunohistochemical examination revealed eleven malignant masses; eight rhabdomyosarcomas, a leiomyosarcoma, a liposarcoma and a large B cell lymphoma. Other excised masses were benign and infective lesions. CONCLUSION: Paratesticular masses are heterogeneous tumours that follow different clinical courses. Clinicians must be aware of this histological diversity in order to plan a treatment pathway. This study is one of the largest published series, with a long follow-up period. It shows that the most critical features in determining prognosis are histopathological subtype and tumour grade.

Regression of the Sweet's syndrome after Bacillus Calmette-Guérin therapy: A bladder cancer case report.

The Sweet's syndrome is a rare dermatosis which can be related to underlying malignancies. In this case we presented a case, who applied to our clinic with severe dermatosis and hematuria. We diagnosed high grade non-muscle invasive bladder tumor, which was treated with transurethral resection of bladder-tumor and six cycle of Bacillus Calmette-Guérin therapy. After the treatment the dermatosis was regressed almost completely. However, recurrent bladder tumor was detected at the first control cystoscopy.

The rupture of an abdominal aortic aneurysm at the level of horseshoe kidney: A case report.

Kidney anomalies are always a challenge even for the most experienced vascular and urologic surgeons in the reconstruction of the abdominal aortic segment. In the literature, the most common anomalies of the kidney are the horseshoe kidney. THE CASE: A 77-year-old male headed to the emergency department with complaints of acute abdominal pain and sudden onset of fatigue. The enhanced CT-scan performed and the horseshoe kidney with the ruptured aortic aneurysm seen. The cardiovascular and transplantation surgery team decided to perform explorative surgery.

First live donor nephrectomy with abdominal tortuous aorta and two renal arteries: A renal transplantation case report.

46-year-old wife (donor) and 52-year-old husband (recipient) admitted to our clinic for kidney transplantation. CT angiography of the donor showed us there were bilateral renal double artery and a tortuous aorta that is deviated to the left side. The main artery cannot be reached by laparoscopy because of the upper level of renal artery and deviation of the aorta and an open conversion was performed. Presence of tortuous aorta with multiple renal arteries makes laparoscopic donor nephrectomy a challenging procedure even preformed by an experienced surgeon. The possibility of open conversion should always be kept in mind in these cases.

Sarcoidosis is a rare cause of infertility: A case report.

In this paper, we presented a patient, who applied to our clinic because of infertility. After an intensive investigation, we diagnosed systemic sarcoidosis with testicular involvement. Urogenital sarcoidosis is a rare and insidious condition, however, it can lead to infertility. Therefore, following the diagnosis, we applied systemic steroid therapy to the patient. Within one year, the patient had a child without assisted reproductive techniques. According to our experience, in this case, we concluded that infertility without an etiology should be investigated elaborately. Furthermore, urogenital sarcoidosis should keep in mind as a rare etiology.

A purely penoscrotal approach: Reservoir placement of an inflatable penile prosthesis (IPP) in an orthotopic neobladder patient. Case report.

INTRODUCTION: The inflatable penile prosthesis (IPP) is the last step in drug-resistant erectile dysfunction treatment. IPP implantation can be challenging, especially following a cystoprostatectomy with an orthotopic neobladder. There is no consensus about surgical techniques for placement of an IPP reservoir in such patients. In this paper, we present a case of an IPP and reservoir placement with a single penoscrotal incision. CASE: A 55-year-old patient, who underwent radical cysto-prostatectomy with an orthotopic neobladder seven years ago, presented with severe erectile dysfunction. His oncologic status was stable, and he was in remission. He also had high blood pressure and took medication for it. He previously used different medical treatments, such as oral phosphodiesterase-5 inhibitors (PDE5i), intraurethral prostaglandin E2 (PGE2) installations, and Trimix injections. As far as we know, he had no benefit from these treatments. A three-piece IPP was recom- mended. After a discussion of surgical techniques, we chose the penoscrotal approach, and the ectopic reservoir was placed through the inguinal canal, guided by a forefinger. RESULTS: The total operative time was 60 minutes, and the estimated blood loss was minimal. There were no perioperative complications. The patient was discharged on postoperative day one. He could start to use the IPP in the first month. His sexual and urinary functions were normal, and there was no abdominal bulging from the ectopic reservoir at the three-month follow-up. CONCLUSIONS: In conclusion, ectopic placement of the reservoir through a single penoscrotal incision appears to be a safe and acceptable surgical technique for postoperative ED following a radical cystoprostatectomy with an orthotopic neobladder.

Kidney Transplantation Outcomes in Temporarily Protected Syrian Patients With End-Stage Renal Failure in Turkey.

BACKGROUND: Approximately 6.3 million Syrian people migrated to other countries due to war since 2011. There are more than 3.5 million Syrian people living in Turkey under temporary protection. Syrian people receive free health care in Turkey, including kidney transplantation. Our institution started a kidney transplantation program about 3 years ago. It is the first institution performing living, related kidney transplantation for Syrian patients with end-stage renal failure. METHODS: All living, related kidney transplantations to Turkish and Syrian patients from the beginning of our transplantation program until September 2018 were enrolled in this study. Donor and recipient characteristics, induction and maintenance immunosuppression, length of hospital stay, creatinine values at first week and first month, treatment incompatibility, and graft survival were evaluated. RESULTS: Of the 25 living, related kidney transplantations 20% were Syrian. Three of 5 Syrian recipients were in the pediatric age group. None of the Syrian transplantations were preemptive, while half of the Turkish transplantations were preemptive (P = .005). Immunosuppression protocols, creatinine values, length of hospital stay, and graft survival rates were similar between groups. None of the Syrian recipients had treatment incompatibility (0%), unlike the Turkish recipients (15%). CONCLUSION: Outcomes of kidney transplantation for Syrian recipients are similar to those of Turkish recipients. Having this no-cost facility is great for Syrian kidney failure patients. The number of transplantations for Syrian patients under temporary protection in Turkey is expected to increase in the future, with these favorable results and easy to access, free health care facilities.

Plication without degloving - Safe and effective approach for correcting lateral and dorsal penile curvature: Case series.

Penile curvature deformities are often manageable with surgical reconstruction methods. We aimed to show the safety and efficacy of ventral and dorsal plication techniques without degloving in our two patients who have penile curvature. Two young adults, aged 20 and 23 years, presented to our clinic with lateral and dorsal penile curvatures. This problem has been sustaining since their teenage. Following the required preparations, two surgical techniques were used, namely Nesbit and Lue's "16-dot" technique. Patients completed a satisfaction survey at a mean of 6 months later the surgery. Although both patients reported a subjective decrease in penile length, their satisfaction rate was high. Penile plication without degloving is a safe and effective technique for correcting dorsal and lateral penile curvatures.

The rarest phenomenon of flexible ureterolithotripsy: Kidney stone in supernumerary type combination with a horseshoe kidney.

The horseshoe kidney (HSK) is common and supernumerary kidney is the rarest developmental anomaly of the urogenital system. The supernumerary kidney in a HSK conjunction is extremely rare, and prevalence of it is unknown. A review of literature, there have been a few case reports about the supernumerary and HSK combination, however, none of which also had a concomitant kidney stone and obstructive pathology. Our case indicated that patient referred to flank pain and visible hematuria to our clinic, and further investigations demonstrate supernumerary kidney in a horseshoe configuration and kidney stone. Kidney stone could not be found at the first attempt because of the anatomical malformation. Retrograde pyelography showed ureteral branching and helps to define the placement of stone. This stone was fragmented with flexible ureteroscopy in the lower pole of the middle kidney in the second session. There was no stone fragments absence at the 1st-month control. This exceedingly rare type case should be evaluated meticulously on preoperative duration otherwise can be a challenge for surgeons. Visualize pelvicalyceal system under the fluoroscope is a vital step in this regard to being guidance during the procedure.

Evaluation of per-operative cough stress test during transobturator mid-urethral sling surgery.

PURPOSE: Currently, it is unclear how the mesh tension should be adjusted on the transobturator tape surgery (TOT) for improving continence. The aim of this study was to evaluate the effects of per-operative cough stress test on TOT. MATERIALS AND METHODS: Between March 2007 and December 2011, 206 women with SUI were enrolled in this study. Patients were randomly categorized to treatment with TOT (96) or TOT with cough stress test (110). The IIQ-7 and the UDI-6 were used to identify satisfaction level. At the end of 1st year, two groups were compared patient characteristics, operation time, duration of hospital stay, cure and complication rates. RESULTS: The cure rate was 84.37% 81/96) versus 83.63% (92/110) in TOT and TOT with cough test groups, respectively. Postoperatively ten patient (10/110, 9.09%) suffered voiding difficulties (> 250 ml residual urine) in TOT with cough stress test group. Five patients were discharged with transurethral catheter, whereas, in traditional TOT group, two patients (2/96, 2.1%) had transient postoperative voiding difficulty and two patients were treated with repeated catheterization for 1 week (p < 0.05). Postoperative groin pain was present in 7/96 (8%) versus 24/110 (22%) in TOT and TOT with cough test groups, respectively (p < 0.05). TOT with cough stress test group had an higher rate of complications like, retention of urine, necessitating to cut the tape, mesh erosion and pain in groin or leg. No patient had resistant voiding difficulty or prolonged urinary retention (> 1 week) in traditional TOT group. CONCLUSIONS: We believe that per-operative cough stress test leads to overtreatment of stress urinary incontinence when the complication rates were considered.

A rare malformation of urinary system: Right ectopic thoracic kidney.

An ectopic kidney is a common developmental anomaly of the urinary system. However, the thoracic kidney (TK) is the rarest state form of an aberrant kidney. The aim of this case report is defining the symptoms in TK diagnosis and constructing a treatment model will promote the best outcomes. These patients come to the physician with the various symptoms, and they could be diagnosed incidentally. In our case, we describe 40 years female patient with severe respiratory problems and upper back pain. In the pulmonary clinic, suspected mass was diagnosed with chest X-ray, and computerized tomography detected nontraumatic nonhernia associated, a truly ectopic TK. Moreover, the thoracic surgeon and urologist team decided to exploration and reconstructed the right ectopic kidney. The 1st month of the control of patient symptoms was disappeared. Overall, TK should be kept in mind in the differential diagnosis of thoracic tumors. Surgical exploration and reconstruction should be thought in patients who have severe respiratory symptoms.

Genital Self-mutilation Case in High-level Educated Person.

Self-mutilation is the deliberate direct injuring of body tissue, often done without suicidal intention. Genital self-mutilation is a very rare event and self-harm of the penis, especially in the genital system is exceedingly rare. Generally, this kind of behavior is related to psychotic disorders but can sometimes be seen in non-psychotic people due to bizarre autoerotic acts, a desire for to change sex or religious beliefs that view sexual intercourse as a sin. Our case was the reported genital self-mutilation as a result of the bizarre sexual arousal of a young man who is employed as an architect.

Selective Nuclear Factor Kappa b (NFkB) Inhibitor, Pyrrolidium Dithiocarbamate Prevents, Long-Term Histologic Damage in Ischemia-Reperfusion Injuries after Delayed Testicular Torsion.

PURPOSE: Nuclear factor kapa b (NFKB) is a transcription factor that is required for cytokine-mediated induction of the human inducible nitric oxide synthase (iNOS) gene. Recent studies have shown that in the pathophysiology of ischemia-reperfusion (IR) injuries NFKB is involved. In our study we aimed to determine the efficacy of the selective NFKB inhibitor, pyrrolidium dithiocarbamate (PDTC), on long-term histological damage in testicular IR injuries. MATERIALS AND METHODS: Twenty-one adult male Wistar albino rats were divided into 3 equal groups. In groups 1-2, the left testes in rats underwent 4 hours of 720° experimental torsion. In group 2, PDTC (100 mg/kg) was administered intraperitoneally in the last 1 hour before detorsion; and group 3 underwent a sham operation. All rats underwent bilateral orchiectomy 45 days after the experiment. The testes weights were measured and compared to the other groups and their contralateral values. Testes samples were fixed with Bouin solution for histological (Johnsen score) and immunohistochemical examination. Immunohistochemically iNOS and an active subunit of NFKB, p65 were evaluated using mouse primary monoclonal antibodies and were evaluated semi quantitatively. RESULTS: Testicular weights and Johnsen scores in ipsilateral testes were 0.67 ± 0.85, 1.54 ± 0.11, 1.84 ± 0.64 and 1.63 (1-4), 6.94 (4-10), 5.29 (1-9) in the torsion, sham and PDTC groups, respectively. In contralateral testes the same values were 1.74 ± 0.84, 1.59 ± 0.13, 1.50 ± 0.54 and 5.38 (2-8), 7.17 (5-10), 6.30 (4-9). Testicular weights and Johnsen scores were significantly different in the ipsilateral torsion group (P < .05). In the PDTC group testicular weights and Johnsen scores were similar with the control group (P > .05). Immunohistochemically there was marked staining in the iNOS and p65 expressions in the torsion group compared with group 2 and 3. In rats administered PDTC, iNOS and p65 expressions were significantly reduced compared with the torsion group. There were no significant differences between the histological and immunohistochemical results of groups 2 and 3. CONCLUSION: This data suggests that IR induces iNOS expressions through the activation of NFKB, p65. The NFKB pathway plays major role in testicular reperfusion injuries. It is possible to prevent reperfusion injuries using selective the NFKB inhibitor. .
