“…Congenital anomalies of the upper urinary tract comprise a diversity of abnormalities, including aberrant location, orientation and shape of the kidney, as well as variation of the collecting system and blood supply (6). The anatomic properties of anomalous kidneys present substantial obstacles to endourological procedures as consequence of the anatomical alterations, in special the position of the renal calices (18)(19)(20).…”

Purpose: To analyze the 3-dimensional intrarenal anatomy of horseshoe kidneys (HK) and kidney with complete ureteral duplication (CUD), in polyester resin endocasts of the collecting system and in patients submitted to 3D computerized tomography scan (CT-scan). Materials and Methods: We analyzed seven 3-dimensional polyester resin endocasts of the kidney collecting system obtained from 6 fresh adult cadavers (4 with unilateral CUD and 2 with horseshoe kidney) and CT-scan reconstruction images of kidneys from 24 patients: 6 patients with HK, 8 with CUD and 10 patients without renal anomalies that were used as controls. We analyzed the spatial distribution of the calices, the infundibula diameters, the angle between the lower infundibulum and the renal pelvis (LIP) and the angle between the lower infundibulum and the inferior minor calyces (LIICA). Measurements of the width and length of the inferior infundibulum and the infundibula of the minor calyces, as well as the angles (LIP and LIICA) were made with the aid of the LibreOffi ce 6.3 software. The data were analyzed with the IBM® SPSS® Statistics. Results: There was no statistical difference in the inferior pole measurements between the groups with anomalies and the control group, both in polyester resin endocasts and CT-scan reconstruction images for LIP. When we compared the LIP in the CT-scan between HK versus CUD (p= 0.003), and HK versus the control group (p= 0.035), we observed statistical difference. Conclusions: The knowledge of spatial anatomy of lower pole is of utmost importance during endourologic procedures in patients with kidney anomalies. In the present study we observed that horseshoe kidneys had more restrictive anatomic factors in lower pole than the complete ureteral duplication.

“…Multiple authors report management of urinary calculi in patients with complicated urologic anatomy such as horseshoe, pelvic, or crossed-fused ectopic kidneys. 1,2 One case report of an adult patient with an ectopic kidney who underwent transgluteal PCNL exists, 3 but to our knowledge, this is the first report of a percutaneous transgluteal approach in a pediatric patient with an ectopic kidney and urologic reconstruction. The patient presented here had not only a pelvic kidney, but multiple reconstructive surgeries for cloacal exstrophy closure and subsequent abdominal wall reconstructions with synthetic mesh material.…”

“…Compared with normal kidneys, the cause for higher prevalence of complications in HSK is its special anatomical structure. As a result of this fusion, complications including hydronephrosis, urinary tract infection, renal calculi and so on arise [1]. Therefore, even with all the advancements in the development of minimally invasive techniques, HSK stones remain a unique challenge to the urologist.…”

Objective: To assess the safety and efficacy of retroperitoneoscopy technique-assisted percutaneous nephrolithotomy (PCNL) used in the treatment of complexity horseshoe kidney (HSK) with renal stones. Methods: Between January 2012 and April 2015, 5 patients with renal stones in complexity HSK underwent retroperitoneoscopy technique-assisted PCNL. The perioperative data analyzed, included operation time, blood loss, incidence of complication rate, the stone-free rate (SFR), and so on. Results: All the patients successfully completed the operation without need for an open surgery. The mean operative time in which this procedure was done was 77.5 ± 20.6 min, the mean hemoglobin that was reduced was 2.5 ± 0.8 g/dl, the mean time to remove nephrostomy tube and retroperitoneal tube were 3.0 ± 1.0, 3.5 ± 1.0 days, respectively. The mean hospital stay was 7.0 ± 1.5 days. The SFR of all the patients was 80% (4/5). One patient who had residual stones (6 × 5 mm) in the middle pole underwent additional shock wave lithotripsy after the operation and no serious perioperative complications were noticed. Study limitations include small sample size and short follow-up time. Conclusions: Retroperitoneoscopy technique-assisted PCNL is a feasible, safe, and an effective alternative to laparoscopic pyelolithotomy for treating complexity HSK with renal stones, especially in a situation where the HSK is tightly wrapped by the surrounding organs.
