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.

Impact of Extracorporeal Stent Placement during Laparoscopic Pyeloplasty on Operative Duration.

Objectives: Ureteric stent insertion during laparoscopic pyeloplasty is the common practice for the reconstruction of ureteropelvic junction obstruction (UPJO). The long and hard learning curve of the method leads still controversy among surgeons. The utility of extracorporeal stent insertion in terms of shortening the length of operation time will be discussed in this study.

Does maternal exposure during pregnancy to higher ambient temperature increase the risk of hypospadias?

Introduction: The association between ambient temperature that the mother is exposed to during pregnancy and hypospadias has not been investigated by the studies, although the recent studies showed the correlation between some congenital malformations (congenital heart disease, neural tube defect, etc.) and ambient temperature.

Objective: The aim was to investigate the relation between hypospadias and the ambient temperatures that the mother is exposed to during her pregnancy.

Comparison of laparoscopic and open ureterolithotomy in impacted and very large ureteral stones.

Purpose: To compare the efficacy of laparoscopic and open ureterolithotomy in patients with ureteral stones.

Materials And Methods: Patients who had undergone open or laparoscopic ureterolithotomy between 2001 and 2013 in our clinic were enrolled in the study.Ureterolithotomy was performed due to the following reasons: failure to position the patient for ureteroscopy, unreachable stone with ureteroscopy also use of balloon dilatation, high stone volume, and the need for removal of kidney stones at the same session.

"Snodgraft" technique for the treatment of primary distal hypospadias: pushing the envelope.

Purpose: "Snodgraft" modification has been proposed to reduce the risk of meatal/neourethral stenosis in distal hypospadias. We applied the Snodgraft technique by using inner preputial graft in primary distal hypospadias repair.

A case of primary lymphoma of the bladder managed with multimodal therapy.

Background: A 65-year-old female patient presented to a urology department with macroscopic hematuria, dysuria, urinary frequency and urgency. One year previously, she had visited a urologist because of a 1-month history of hematuria, dysuria, urinary frequency and urgency. She had subsequently undergone successful, simultaneous surgeries for resection of a basal cell carcinoma of the nasal skin and lymphoma of the bladder.

Do lifestyle changes work for improving erectile dysfunction?

The main cause of erectile dysfunction (ED) is organic in nature, with vascular etiologies being the most common risk factors. Although there have been sufficient data on the relationship between ED and several well-recognized risk factors, including aging, coronary artery disease, atherosclerosis, diabetes mellitus, dyslipidemia, high blood pressure, and pelvic surgeries, little attention has been paid by the urologists to the role of lifestyle factors in ED. However, accumulating data from basic science and clinical studies have determined a link between the occurrence of ED and a number of lifestyle factors, such as smoking, obesity, alcohol consumption, and lack of physical activity.

Healing of the urethral plate after deep incision: does catheterization change the course of this process?

Background: We aimed to evaluate the sequence of healing process as well as possible effects of stent placement on the healing process after deep urethral plate incision.

Methods: A deep urethral plate incision was done at the 12 o'clock position. After that, in the first group (n = 14) the anterior urethra was stented with a silicon catheter.

The learning curve in the training of percutaneous nephrolithotomy.

Objectives: To investigate the learning curve in the training of percutaneous nephrolithotomy (PCNL).

Methods: A total of 104 PCNL cases were included in this evaluation to define the learning curve of a surgeon with no previous experience at performing solo PCNL. Two parameters of expertise were reviewed, namely the operation and fluoroscopic screening times.

Single stage Fowler-Stephens orchidopexy: a preferred alternative in the treatment of nonpalpable testes.

In this present study we aimed to discuss the surgical efficacy of single stage Fowler-Stephens orchidopexy (FSO) technique, with an emphasis on its practical and logical application that may be kept in mind during a standard orchidopexy procedure. Twenty-two children have undergone a single stage FSO procedure for nonpalpable testes during the last 9 years in our department. Surgical procedure was initiated with a standard inguinal oblique incision keeping in mind that depending on the position and the anatomic features of the testes a FSO method might be needed.
