Objective: In this study, we aimed to describe the timing of contralateral testicular fixation with our ten year results in postpubertal patients with testicular torsion with a patient-based approach.

Methods: Postpubertal patients diagnosed with testicular torsion in a tertiary hospital between January-2012 and September-2022 were divided into 2 groups according to the "patient-based approach" criteria we adopted in our clinic. Group 1 in whom the contralateral teste was fixed in the same surgical act and group 2 in whom the fixation was deferred.

Background: Bladder paraganglioma is a neuroendocrine tumor that accounts for less than 0.1% of all bladder tumors. Symptoms caused by catecholamine release such as hypertension, palpitation, syncope, and macroscopic hematuria are the most common findings.

Article Synopsis
  • The article investigates how multiparametric magnetic resonance imaging (mpMRI) can improve prostate cancer diagnosis before conducting standard tru-cut biopsies in patients.
  • In a study involving 160 patients, mpMRI guided the biopsy process, showing significant differences in prostate-specific antigen levels between cancer and benign cases.
  • Results indicated that mpMRI results and biopsy findings were in complete agreement for identifying cancer zones, with the likelihood of adenocarcinoma significantly rising alongside increased mpMRI risk scores.

The current study investigates the biochemical and histopathological effects of taxifolin on acrylamide-induced kidney damage. A 50 mg/kg dose of taxifolin was administered via oral gavage to the taxifolin + acrylamide (TACR) group (n-6) consisting of male albino Wistar rats. The same volume of distilled water used as solvent was orally administered to the acrylamide (ACR) (n-6) and healthy (HG) (n-6) groups.

Background: It has been reported in the literature that proinflammatory interleukin-1 beta (IL-1β) is increased in cases of testicular ischemia reperfusion (I/R) damage. This information suggests that anakinra, an IL-1β antagonist, may be effective in testicular I/R damage.

Objective: In our study, we investigated the effect of anakinra on testicular I/R damage induced in rats with torsion/detorsion.

Etoricoxib features antioxidant and anti-inflammatory properties concomitantly, suggesting that it may be beneficial in testicular ischemia reperfusion (I/R) damage. Our aim is to investigate the effects of etoricoxib on testicular I/R damage induced with torsion-detorsion (TD). The etoricoxib + torsion-detorsion (ETD) groups of animals were given etoricoxib in 50 and 100 mg/kg of body weight (ETD-50 and ETD-100), while the testes torsion-detorsion (TTD) and sham operation rat group (SOG) animals were given single oral doses of distilled water as a solvent.

Background: Urethral polyps are rare benign pathologies seen in the male posterior urethra, more frequently originating from verumontanum. In this article, we aimed to discuss diagnosis and treatment of a urethral polyp causing hematuria and urinary infection in a 3-month-old male infant. This is the first case in the literature in which a urethral polyp is treated with Holmium yttrium-aluminum-garnet (YAG) laser.

The objective of our study is to research biochemically and histopathologically the effect of nimesulide on oxidative damage inflicted by ischemia-reperfusion (I/R) on the rat renal tissue. Twenty-four albino Wistar type of male rats were used for the experiment. The animals were divided into groups as: renal ischemia-reperfusion control (RIR), nimesulide+renal ischemia-reperfusion of 50 mg/kg (NRIR-50), nimesulide+renal ischemia-reperfusion of 100 mg/kg (NRIR-100), and sham groups (SG).

Article Synopsis
  • * The tumor's characteristics often lead to confusion with sarcomatoid renal cell carcinoma, high-grade renal carcinoma, or sarcoma.
  • * A case study of a 32-year-old woman with a renal epithelioid angiomyolipoma is presented, where imaging findings resembled urothelial cell carcinoma in the upper urinary tract.

Object: We present the efficacy of shockwave lithotripsy (SWL) therapy administered with sedoanalgesia in infants with kidney stones.

Materials And Methods: We enrolled 102 patients aged 5-24 months who had kidney stones and received SWL therapy under sedoanalgesia using a Siemens Lithostar Modularis device. Patient and stone characteristics, therapy parameters, pain score, complications, discharge time, and follow-ups were registered and evaluated.

Objectives: The aim of this study was to assess the safety and effectiveness of ureteroscopy and Holmium: Yttrium-Aluminum-Garnet lithotripsy for the treatment of ureteral stones with different localizations in symptomatic pregnant women.

Methods: A retrospective analysis was performed on 19 pregnant patients referred to our center between January 2005 and December 2012 with symptomatic hydronephrosis requiring surgical intervention. 7.

The aim of this study was to determine long-term efficacy and safety subcutaneous injection of interferon-alpha-2B in patients with mumps orchitis in terms of testicular volume and other testicular functions. Mumps orchitis was evaluated in 37 patients. Patients were hospitalized and administered 1 × 3,000,000 IU subcutaneous injection of interferon-alpha-2B daily for 7 days.

Background: Although various local anesthesia techniques have been suggested to decrease pain and discomfort during a transrectal ultrasound (TRUS)-guided prostate biopsy, the best method has not yet been defined. The present prospective, double-blind, randomized study aims to investigate the clinical efficacy of 'walking' caudal block compared with an intrarectal lidocaine gel for this procedure.

Methods: One hundred patients were randomly assigned to two groups.

Fever may appear due to known causes such as infections, but may sometimes occur as a result of unknown pathologies. These pathologies can be included in a miscellaneous group of fever of unknown origin. We report one case of bladder stone including a foreign body in a 40-year-old man with a stroke admitted for high fever, blocked miction and bladder symptoms.

Technological advances in the design of shock wave lithotriptors have precipitated important changes in the management of urolithiasis in children. New generation lithotriptors have reduced the need for anesthesia, lowered hospitalization duration, and resulted in better fluoroscopic targeting reducing radiation exposure. Currently, shock wave lithotripsy (SWL) has become standard first line treatment for most renal and ureteral calculi in children.

Introduction: Penile fracture is the rupture of the tunica of one or both corpora cavernosa due to direct blunt trauma to the erected penis. Partial or complete rupture of the urethra or injury to the deep dorsal vein may accompany penile fracture.

Aim: To compare conservative and surgical treatment modalities in terms of duration of hospitalization, early and late complications such as penile nodule and curvature, erectile dysfunction, and painful erection.

In this study, we aimed to compare the treatment results of two different shock wave lithotripsy (SWL) machines used in the management of pediatric urolithiasis. Between January 1993 and October 2004, Dornier MPL 9000 (electrohydraulic) had been used, and since then Siemens Lithostar Modularis (electromagnetic) has been used. The last evaluation was done 3 months after SWL treatment in terms of the success rate, use of anesthesia and complications.

Objective: Nephroureterectomy with the removal of the ipsilateral ureteral orifice and bladder cuff en bloc remains the gold standard treatment for upper urinary tract urothelial cancer. The distal ureter can be removed with the open surgical technique or endoscopic approach. We compared the outcomes of the endoscopic approach with those of conventional open surgery on the distal ureter.

Testicular granulosa cell tumors are extremely rare in adults. We report a case of a testicular germ cell tumor (GCT) in a 21-year-old man. The tumor was treated successfully with radical orchiectomy, and follow-up computed tomography revealed no evidence of recurrence or metastasis 10 months postoperatively.

In the present study, we aimed to evaluate the effects of dehydroepiandrosterone (DHEA) on apoptosis of testicular germ cells after repair of testicular torsion in rats. Twenty-four adult male Sprague-Dawley rats were randomly divided into four groups, with six rats in each group: sham operation, torsion/detorsion (T/D), T/D + vehicle, and T/D + DHEA. Three hours before detorsion, 50 mg kg(-1) DHEA was given intraperitoneally to T/D + DHEA group.
