Testis-sparing Surgery in Adult Patients with Germ Cell Tumors: Systematic Search of the Literature and Focused Review.

Testis-sparing surgery (TSS) is a guideline-recommended treatment option for men with synchronous or metachronous bilateral testicular germ-cell tumor (GCT) or GCT in a solitary testicle. The tumor volume should not exceed 50% of the total testicular volume and serum concentrations of both testosterone and luteinizing hormone should be within the normal ranges. After tumor enucleation, patients should undergo adjuvant radiation of the testicle in case of germ cell neoplasia in situ.

A review study to evaluate holmium:YAG laser lithotripsy with flexible ureteroscopy in patients on ongoing oral anticoagulant therapy.

The objective of this study was to evaluate the safety and efficacy of flexible ureteroscopy (FURS) and holmium:YAG laser lithotripsy for the treatment of upper urinary tract stones in patients on active oral anticoagulants. The records of 1081 patients who underwent flexible ureteroscopic holmium:YAG (Ho:YAG) laser lithotripsy for upper ureteral and renal calculi from 1999 to 2015 were retrospectively reviewed. A total of 84 patients on continuous oral anticoagulation or antiplatelet therapy (warfarin, aspirin, or clopidogrel) were identified.

Impact of obesity on functional and oncological outcomes in radical perineal prostatectomy.

Introduction: We evaluated the impact of obesity on perioperative morbidity, functional, and oncological outcomes after radical perineal prostatectomy (RPP).

Methods: A total of 298 consecutive patients underwent RPP at our institution. Patients were categorized into 3 groups based on their body mass index (BMI): Normal weight <25 kg/m(2) (Group 1), overweight 25 to <30 kg/m(2) (Group 2), and obese ≥30 kg/m(2) (Group 3).

Intraoperative Evaluation of Ureteral Access Sheath-Related Injuries Using Post-Ureteroscopic Lesion Scale.

Objective: In the present study, intraoperative ureteral injuries inflicted during retrograde intrarenal surgery (RIRS) with ureteral access sheath (UAS) use were evaluated using the Post- Ureteroscopic Lesion Scale (PULS).

Materials And Methods: Patients in whom a UAS was used during RIRS and for whom ureter images were video recorded during the procedure were included in the study. PULS grading was performed after UAS removal, and video sequences of all patients were viewed by a junior resident, a senior resident, and four experienced urologists and assessed according to the PULS.

A rare complication of ureteral double-J stenting after flexible ureteroscopy: renal parenchymal perforation.

Double-j (DJ) ureteral stenting is a very common procedure performed after various endourological procedures. Although several complications due to DJ stent insertion were revealed, only three cases of renal parenchymal perforation have been reported to date. We present a case of a 35-year-old woman who had perforation of renal parenchyma without perirenal hematoma following insertion of DJ ureteral stent after flexible ureteroscopy for the treatment of an upper ureteral calculi.

Subepithelial pelvic hematoma of the kidney (Antopol-Goldman Lesion).

Renal pelvic hematoma (Antopol Goldman lesion) is a rare but significant condition that may clinically mimick a renal or a pelvic neoplasm. Differential diagnosis and optimal treatment are still not known certainly. A 80-year-old male patient admitted to the emergency department with gross hematuria/clot retention and right flank pain.

A comparison of 120 W laser photoselective vaporization versus transurethral resection of the prostate for bladder outlet obstruction by prostate cancer.

Objective: To compare the mid-term outcomes of photoselective vaporization of prostate (PVP) with GreenLight HPS 120 W laser and transurethral resection of the prostate (TURP) for obstructive lower urinary tract symptoms (LUTS) in men with prostate cancer (CaP).

The purpose of the current study was to evaluate the efficacy and safety of laser prostatectomy by using the latest 180-W XPS GreenLight laser with the new MoXy fiber in the surgical treatment of glands larger than 80 mL in a prospective study. From December 2011 to May 2013, 68 consecutive patients with a mean age of 71.1 ± 9.

Is retrograde flexible nephrolithotripsy feasible for calyceal diverticular stone?

The aim of this study is to manage the calyceal diverticular (CD) stone, several treatment options were applied but it is still a challenging condition of endourology. In this retrospective study, we aim to report the results of our patients with CD stones treated with retrograde flexible nephrolithotripsy (RFNL). A total of 47 patients (55 procedures) who underwent RFNL by a single surgeon for CD stones from January 2004 to March 2013 were evaluated retrospectively.

Treatment of renal stones with flexible ureteroscopy in preschool age children.

The aim of the study is to evaluate the efficacy and safety of retrograde intrarenal surgery (RIRS) to treat renal stones in preschool age (<7 years) children. From September 2005 to May 2013, a total of 65 children (31 boys and 34 girls) with 72 renal stones were treated using RIRS. Patients were considered stone-free when the absence of residual fragments was observed on imaging studies.

The all-seeing needle instead of the Veress needle in pediatric urologic laparoscopy.

Purpose: To investigate the feasibility of the all-seeing needle for safe entry and creation of pneumoperitoneum in pediatric urologic laparoscopy.

Patients And Methods: A total of 14 children underwent various transperitoneal urologic laparoscopic procedures. The all-seeing needle, which is 4.

Evaluation of urinary oxalate levels in patients receiving gastrointestinal lipase inhibitor.

Objective: The purpose of this study was to examine the possible effects of a gastrointestinal lipase inhibitor "Orlistat (Xenical)" on the intestinal absorption of oxalate and thereby on the urinary levels of oxalate excretion in overweight patients.

Methods And Procedures: Long-term follow-up data of 95 cases (57 men, 38 women; M/W=1.5) were documented.

Effect of being overweight on stone-forming risk factors.

Objectives: To evaluate the possible role of being overweight on stone-forming risk factors.

Methods: A total of 264 patients were included in the study. After a detailed stone disease history, the systolic and diastolic blood pressure was precisely measured and recorded for all patients, and the body mass index, 24-hour urine composition, and serum stone-forming risk parameters were evaluated in overweight (n = 164; 52 men and 112 women; group 1) and normal (n = 100; 44 men and 56 women, group 2) patients.

Methods: Seventy-six consecutive patients with enlarged prostatic adenomas of 70 to 100 mL were randomly assigned for surgical treatment with TURP (n = 37) or PVP (n = 39). International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF-5) scores, maximum flow rates (Qmax), postvoid urine residues (PVR), and transrectal ultrasound (TRUS) volumes were recorded.

Effect of verapamil on urinary stone-forming risk factors.

Prevention of recurrent stone formation will only be possible with careful metabolic evaluation and appropriate management. In this present prospective study, a total of 95 patients with calcium oxalate (CaOx) stone disease were evaluated with respect to the effects of a calcium channel blocking agent (verapamil) therapy on stone-forming risk factors. A total of 95 patients with CaOx urolithiasis were well evaluated for the possible specific effects of verapamil administration on stone-forming risk factors during long-term follow-up.

Operative failure during ureteroscopic pneumatic lithotripsy: factors affecting successful outcome.

Aim: We aimed to evaluate the predictive factors that would in turn indicate stone migration and the effects of these factors on the ultimate success of the intervention.

Method: Patients were divided into two groups with respect to the migration of the stone treated. Group I: patients demonstrating stone migration during manipulation; group II: no migration of the stones noted.

Testicular blood flow measurements and mean resistive index values after microsurgical and high ligation varicocelectomy.

Objectives: To compare the effects of the two most commonly used surgical methods in the management of varicocele disease, namely, microsurgery and high-ligation varicocelectomy, on testicular blood flow changes and mean residual index values in a prospective randomized study.

Methods: A total of 56 patients clinically diagnosed with varicocele were randomized into two groups: 28 were selected for high-ligation surgery and 28 for microsurgery. The testicular blood flow was evaluated in all patients before and 7 days after surgery, and the maximal flow velocity (Vmax), minimal flow velocity, and resistive index were measured.
