    The incidence and location of prostatic calculi on noncontrast computed tomography images in patients with renal calculi
    (Springer, 2015) Balasar, Mehmet; Poyraz, Necdet; Goger, Yunus Emre; Unal, Yunus; Piskin, Mehmet Mesut
    In this study, the incidence and location of prostatic calculi on noncontrast abdominal computed tomography (NCACT) images of patients with and without renal stones were investigated. Between 2006 and 2013, NCACT images were taken of 133 patients treated for renal stones (Group I) and of 100 age-matched control patients with putative urinary stone disease (Group II) in our clinic. The incidence and location of prostatic calculi on these images were determined. The location of prostatic calculus was classified as type A if they were located in the main prostatic ducts, and type B if they were located outside the ducts. Prostatic calculi were present in 44.4 % of patients in Group I and 21.0 % of patients in Group II. The incidence of prostatic calculi was significantly higher in patients with urinary stones compared with those without (P < 0.001). The location of prostatic calculi in Group I included 74.6 % type A and 25.4 % type B while in Group II the locations were 76.2 % type A and 23.8 % type B. The incidence of prostatic calculi is more prevalent in patients with renal stones. On NCACT images, prostatic calculi were mostly detected in the main prostatic ducts, which were defined as type A.

    Incidence of retrorenal colon during percutaneous nephrolithotomy
    (Brazilian Soc Urol, 2015) Balasar, Mehmet; Kandemir, Abdulkadir; Poyraz, Necdet; Unal, Yunus; Ozturk, Ahmet
    Objective: The aim of this study was to investigate retrorenal colon incidence in percutaneous nephrolithotomy (PNL) interventions made in our clinic. Materials and Methods: Clinical data of 804 PNL patients, accumulated over a 7 year period (2006-2012), was surveyed. The patient files were reviewed retrospectively, and only those who had abdominal computed tomography (CT) images before PNL intervention were included in the study. In the CT images, the position of both the ascending and descending colon in relation to the right and left kidneys were evaluated. Results: According to our hospital reports, 394 patients with CT images were included in the present study 27 patients (6.9%) had retrorenal colon, of which 18 (4.6%) were on the left side, 4 (1.0%) on the right side and 5 (1.3%) had bilateral retrorenal colons. Colonic perforation complication was seen only in two patients and the colonic perforation rate was 0.3%. These two cases had no CT images. Conclusions: PNL, in the process of becoming the standard treatment modality, is a safe and reliable technique for renal stone treatment. Colonic injury should be taken into consideration during PNL interventions of the lower pole of the kidney (especially on the left side) due to the location of retrorenal colon.
