Some criteria to attempt second side safely in planned bilateral simultaneous percutaneous nephrolithotomy.

Objectives: To determine the validity of some criteria that could guide in the decision to cancel or proceed with the second side of planned bilateral simultaneous percutaneous nephrolithotomy (bsPCNL).

Methods: Patients with an indication for bilateral PCNL were enrolled in this study. The operation was stopped at the end of the initial side if operative time was >180 min, the hemoglobin level was <11 g/dL, the hemoglobin decrease was >3 g/dL, the systolic arterial pressure was <100 mm Hg, the arterial oxygen saturation was <95%, the arterial blood pH was <7.

Bilateral kidney stones with ureteropelvic junction obstruction.

Background: A 56-year-old male with bilateral flank pain was admitted following diagnosis of bilateral kidney stone disease. He had previously undergone four separate pyelolithotomy sessions (two per kidney), the latest being 14 years prior. At presentation the patient had two stones in the right kidney and seven in the left kidney.

Bilateral disruption of corpus cavernosum with complete urethral rupture.

Penile fracture is a relatively rare condition. We report an unusual case of the bilateral disruption of the corpus cavernosum with complete urethral rupture resulting from blunt trauma during sexual intercourse. The subject underwent emergency surgery with preservation of erectile and voiding functions in the follow-up.

Role of penile electrodermal activity in the evaluation of autonomic innervation of corpus cavernosum.

Electrodiagnostic tests measuring the activities of cavernous smooth muscle and sudomotor structures of penile skin are used in order to evaluate autonomic innervation of the penis. Owing to closeness of these tissues, the interference of sympathetic activity during recording is a possibility. In this study, we investigated this possibility in 10 patients whose cavernosal tissues were destroyed during penile prosthesis implantation by comparing the pre- and postoperative penile skin electrodermal activities.

Percutaneous nephrolithotomy for pediatric stone disease--our experience with adult-sized equipment.

Objective: We evaluated the outcomes and complications of percutaneous nephrolithotomy (PNL) operations performed in pediatric patients using adult-sized surgical equipment at our center.

Material And Methods: The medical and surgical records of 23 children who underwent a total of 25 PNL operations using 24 or 26 F rigid nephroscopes were evaluated retrospectively. The following aspects were considered: stone burden; duration of surgery and complications; details concerning recovery, success, residual fragments and auxiliary procedures; and follow-up details.

Eosinophilic cystitis. A rare inflammatory pathology mimicking bladder neoplasms.

Purpose: We present a large series of eosinophilic cystitis including 8 cases; 3 of them had tumor-like lesions.

Materials And Methods: The archives of pathology clinic of Inonu University Medical Faculty were reviewed from 1988 to 2002. The characteristics of patients and their diseases were recorded.

Polypoid cystitis unrelated to indwelling catheters: a report of eight patients.

Since polypoid cystitis (PC) is generally caused by indwelling catheter use, in order to evaluate the patients with PC unrelated to a intravesical catheter, a retrospective analysis of the records of the Pathology Department of Turgut Ozal Medical Center was performed and this revealed 8 patients. Mean age of the 2 female and 6 male patients was 48 years (28 to 70). None of the patients had bacterial growth in urine cultures.

Single session endoscopic management of intrinsic ureteropelvic junction obstruction and concomitant renal stone disease in a child: a case report.

Background: Percutaneous nephrolithotomy is a well known therapeutic modality for stone diseases of childhood. Antegrade and retrograde endopyelotomies are also well defined options of treatment for secondary ureteropelvic junction obstruction. Yet there are few reports regarding endoscopic therapy of intrinsic ureteropelvic junction obstruction.

Severe renal bleeding caused by a ruptured renal sheath: case report of a rare complication of percutaneous nephrolithotomy.

Background: Percutaneous nephrolithotomy is a minimally invasive intervention for renal stone disease. Complications, which are rare and usually presented as case reports, are diversified as the utilization of the procedure is expanded. The procedure causes less blood loss and less morbidity when compared to open surgical procedures.

The value of the gonadotrophin-releasing hormone test as a prognostic factor in infertile patients with varicocele.

Objective: To determine the value of the gonadotrophin-releasing hormone (GnRH) test in selecting which infertile patients with varicocele would benefit from varicocelectomy.

Patients, Subjects And Methods: The study comprised 30 patients with varicocele who presented between November 1993 and May 1994, and 10 control subjects. The basal serum level of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were determined and all participants given 100 micrograms of GnRH nasally.

Hydronephrotic type of bilateral multicystic dysplastic kidney. An unusual case.

25 year-old pregnant woman was admitted at week 29 of fetal development for routine ultrasonic evaluation of growth. Sonography of the fetal body revealed two cystic anechoic septated structures bilaterally. At autopsy of the stillborn neonate pathology confirmed congenital multicystic dysplastic kidney.

Use of random urine samples to estimate total urinary calcium and phosphate excretion.

Calcium-to-creatinine and phosphate-to-creatinine ratios in random single-voided urine specimens were compared with 24-hour calcium and phosphate excretions, respectively, in 67 subjects who were selected prospectively to represent a wide range of renal and parathyroid function as well as urinary calcium and phosphate loss. Simple linear regression analysis revealed significant correlation between the spot urine calcium-to-creatinine ratio and 24-hour total calcium excretion and between the spot urine phosphate-to-creatinine ratio and 24-hour phosphate excretion. Calculating these simple ratios permits easy, rapid, correct, and inexpensive estimation of the daily urinary calcium and phosphate excretion.
