Infravesical obstruction in a young boy. (Anterior urethral valve with diverticulum)

The reason of the obstructive voiding abnormalities in children may be functional or mechanical. We report an anterior urethral valve associated with a wide mouthed congenital urethral diverticulum in a child. The flap-like distal margin which acts as an obstructing valve and the proximal margin of the diverticulum were incised endoscopically with electrocautery in the midline. He was voiding well in the eight-month followup period. Especially in children with voiding dysfunction, anterior urethra must be examined carefully to prevent misdiagnosis of the recognizable lesions

Acute urinary retention due to cystic echinococcosis: A case report

Urinary hydatidosis is very rare and represents 2% to 4% of all cases of cystic echinococcosis. We present a case of a 21-yearold man with symptoms of frequency, urinary retention and reduced force in urinary stream due to cystic echinococcosis. Anti-Echinococcus granulosus antibodies were determined by echinococcosis western blotting, and pelvic computed tomography revealed a 11 × 14 × 10-cm retrovesical homogeneous cystic mass. The patient underwent surgical intervention; the cystic mass and retrovesical cavity were removed. After a 3-year follow-up period, there was no episode of lower urinary tract symptoms. This case illustrates that cystic echinococcosis should be considered in every case of cystic mass, especially in endemic countries, such as Turkey. © 2012 Canadian Urological Association

Three different techniques for administering analgesia during transrectal ultrasound-guided prostate biopsy: A comparative study

PubMedID: 22397774Purpose: The efficacy of three different analgesic techniques during transrectal ultrasound (TRUS) guided prostate biopsy, including (i) periprostatic blockage (PPB), (ii) intrarectal gel instillation, and (iii) sedoanalgesia were compared. Material and Methods: During a period of five months, 100 consecutive men were enrolled in this study. A 10-point linear visual analogue scale (VAS) was used to assess the pain scores during (VAS 1), immediately after (VAS 2) and one hour after (VAS 3) the needle biopsy procedure. The relationship between the level of pain, prostate volume, age and PSA was determined. Results: There were no statistically significant differences between the four groups in terms of mean age and PSA values. The pain scores were significantly lower in sedoanalgesia and PPB groups (p = 0.0001). There was no statistically significant difference between the groups in terms of complications. Conclusions: In this study, it was shown that patient comfort is better and it is possible to get decreased pain scores with PPB or sedoanalgesia. However, PPB is a preferable method in TRUS-guided prostate biopsy since it is much more practical in outpatient clinics

Prostatic intraepithelial neoplasia in prostate specimens: Frequency, significance and relationship to the sampling of the specimen (A retrospective study of 121 cases)

PubMedID: 10755361Objectives: To determine the frequency of PIN (prostatic intraepithelial neoplasia) in prostate specimens and the relationship of PIN with PCA (prostatic carcinoma) and amount of sampling of the specimen. Materials and methods: All the haematoxylin-eosin stained slides of 121 cases diagnosed between 1990 and 1995 were re-examined retrospectively. The amount of sampling of prostate specimens was also re-examined. Results: PIN was observed in 47.9% of all prostate specimens. The frequency of incidental PIN was 71.4% in cystoprostatectomy specimens. PIN was present in 58.3% of the cases with PCA. We observed foci of high-grade PIN adjacent to sites of invasive carcinoma in 100.0% of prostatectomy specimens with PCA. PIN was high-grade in 100.0% of the carcinomatous prostates with PIN. It was multifocal in 53.4% of 58 cases with PIN. Incidental PCA was identified in 14.3% of cytoprostatectomies for bladder cancer. The average number of paraffin blocks of prostatic tissue was 4.1 (±2.6) in cases with PIN and 3.2 (±1.4) in cases without PIN. Conclusion: In prostate specimens, the determination of PIN is very important since it is the most likely precursor of PCA. The probability of detecting PIN and PCA in a prostate specimen is directly related to the amount of sampling

Scanning laser ophthalmoscopy for early diagnosis of vitreoretinal interfase syndrome

PubMedID: 11989570Purpose: To describe the angiographic signs found using scanning laser ophthalmoscopy for the early diagnosis of vitreoretinal interface syndrome. This method is useful to visualize the inner retinal layers, being more sensitive than fundus biomicroscopy. Material: 61 patients with vitreoretinal interfase syndrome were evaluated. All of them had evidence of this disease using scanning laser ophthalmoscopy but four patients were referred without diagnosis of vitreoretinal interfase syndrome. These patients showed no biomicroscopic signs and diagnosis was made with SLO. Methods: Confocal scanning infrared laser ophthalmoscope (Heidelberg Retinal Angiograph assembled by Heidelberg Engineering). This SLO uses an infrared diode laser source of 795 nm. Conclusion: Patients included were referred with another diagnosis and with this method the correct diagnosis was made. In conclusion scanning laser ophthalmoscopy allows early diagnosis of this pathology for follow-up and treatment

Rigid ureteroscopy for the treatment of ureteral calculi in children.

PubMedID: 15201799PURPOSE: We assess the safety and efficacy of rigid ureteroscopy for the treatment of pediatric ureterolithiasis. MATERIALS AND METHODS: The records of 33 children with an average age of 7.4 years (range 9 months to 15 years) treated with rigid ureteroscopy between May 1995 and July 2003 were reviewed. In 35 ureteral units use of a rigid 6.9 to 10Fr ureteroscope was planned for treating stones at various levels of the ureter. Stones were located in the upper ureter in 6 cases, middle ureter in 3 and lower ureter in 26. Dilatation of the ureteral orifice was necessary in 11 cases. RESULTS: Stone size varied from 3 to 10 mm (mean 5.3). In 33 patients (94%) all stone fragments were removed successfully. Stones were fragmented with pneumatic lithotripsy in 20 cases and removed by forceps without fragmentation in 13. In 1 child an upper ureteral stone migrated up to the kidney during ureteroscopy but following extracorporeal shock lithotripsy therapy she was rendered stone-free. In another child it was not possible to remove the stone. In a 9-month-old female patient with bilateral stones it was not possible to enter the left ureter because of a tight orifice resistant to balloon dilation. At the end of the procedure a 3 or 4Fr ureteral or a 4.8Fr Double-J (Medical Engineering Corp., New York, New York) stent was left in place for 3 days to 3 weeks in 12 cases. There were no cases of ureteral perforation. Of the patients 31 were followed for 1 to 36 months. No incidence of vesicoureteral reflux was detected in 9 who underwent postoperative cystography. CONCLUSIONS: After becoming experienced and meticulously working with finer instruments in adults, rigid ureteroscopy can be a safe and efficient treatment for ureteral stones in every location in children
