“…PCNL to treat urolithiasis is a useful and effective approach in anomoalous kidneys [2][3][4][7][8][9] Horseshoe kidneys are prone to urolithiasis due to stasis from ureteropelvic junction abnormalities, 1 infection, and metabolic derangements. 10 Challenges with performing PCNL in horseshoe kidneys relates to the abnormalities in renal position and malrotation.…”

“…1 Percutaneous nephrolithotomy (PCNL) is effective in managing complex urolithiasis in horseshoe kidneys. [2][3][4] The access is often more inferior and medial than usual due to the decreased renal ascent and rotation anomalies. 5 Complications of PCNL may include bleeding, urinary tract infection, urinary fistula, bowel injuries, and injury to adjacent organs, such as the spleen, liver, and pleura.…”

AbstractTreatment of nephrolithiasis in horseshoe kidneys can be challenging due to anomalies in renal position, collecting system anatomy and vascular supply. We report on a patient who was referred after a failed percutaneous nephrolithotomy for a left moiety staghorn calculus in a horseshoe kidney. Two punctures had been performed involving upper and middle posterior calyces. Both were very medially placed and inadvertently traversed the psoas muscle, resulting in lumbar plexopathy with permanent deficit. This complication presented postoperatively with left leg weakness, paresthesia, and pain which impaired independent ambulation. The patient went on to be successfully treated for her stone disease with robotic-assisted laparoscopic pyelolithotomy.

“…[8] The commonest presentation is the flank pain and is seen in 83% of population with horseshoe kidneys. [9] Although the treatment of nephrolithiasis in horseshoe kidneys is challenging due to anomalies in position of the kidney, the anatomy of pelvic collecting system and vascular supply, percutaneous nephrolithotomy has been accepted as the treatment of choice for stones more than 2 cm. [10,11,12] The dorsomedial orientation of posterior calyces and dorsolateral orientation of anterior calyces offer surprisingly the good percutaneous access.…”

Introduction: The horseshoe kidney is extremely rare, the incidence being one in every 400 - 800 patients. In a recent review of more than 15000 radiographic imaging studies, the incidence was one in every 666 patients. The renal stone formation in horseshoe kidney is around 20-80%. Percutaneous nephrolithotomy is the most accepted modality of treatment . This study was carried out to find the outcome of percutaneous nephrolithotomy in horseshoe kidneys. Methods: Between May 2013 and November 2017, 11 adult patients(12 renal units) with stones in horseshoe kidneys underwent percutaneous nephrolithotomy in the department of urosurgery, Kathmandu Medical College and Teaching Hospital and were evaluated for the operating time, stone free rate , complications and hospital stay. Data analysis was done using Statistical Package for the Social sciences (SPSS) Version 20. Categorical data were analysed by using Fisher exact test. Results: The mean age of the patients was 30.9 years (SD = 10.3) and the mean stone burden was 385.83 mm2 (SD = 331.3). The overall stone free rate was 83.33%. The two patients with residual stones when counselled for Extracorporeal shock wave lithotripsy, refused for it and decided to be on follow up. No auxiliary procedure was done. The complications noted were of Clavien-Dindo grade I and II. No pleural or bowel injury was seen. One patient needed blood transfusion. Conclusions: Percutaneous nephrolithotomy is safe and effective in the management of stones in horseshoe kidneys. It does not carry increased risk than reported in normal kidneys.

“…Renal stones are the most common reason that patients require kidney surgery (2). Abdominal and flank pain (83%) are the most frequently reported symptoms in those who suffer from kidney stones (3). Percutaneous nephrolithotomy (PNL) is the most widely used method in horseshoe kidney patients who have failed other therapy and is the treatment of choice for stones larger than 20 mm (3,4,5).…”

ÖZET amaçAt nalı böbrek olgularında perkütan nefrolitotomi (PNL) tecrübelerimizi paylaşmak. gereç ve yöntemPNL operasyonu uygulanmış at nalı böbrekli 7 hastanın verileri retrospektif olarak analiz edildi. Hastaların preoperatif klinik ve laboratuvar verileri (tam idrar analizi, tam kan sayımı, serum biyokimyası ve koagülasyon testleri) kaydedildi. Taş boyutu (mm 2 ), taşın direkt üriner sistem grafisi üzerine yerleştirilen milimetrik grafik kağıdındaki iz düşümü ile elde edilen boyutlar ile hesaplandı. Ayrıca per-operatif ve post-operatif bulguları değerlendirildi. Başarı ve komplikasyon oranları (Clavien sınıflamasına göre) belirlendi. BulgularOrtalama taş yükü 1234 (dağılım 250-2460 mm 2 ) mm 2 idi. Altı hastaya tek giriş yapılarken sadece bir hastaya ilave girişe ihtiyaç duyuldu. İki hastaya orta kaliks (n=2), dört hastaya üst kaliks (n=4), bir hastaya orta ve üst kaliks (n=1) girişi yapıldı. İki hastaya suprakostal (n=2), beş hastaya subkostal (n=5) giriş uygulandı. Ortalama operasyon süresi 131 (dağılım 70-215 dakika) dakikaydı. Tek seans PNL sonrası taşsızlık oranı %71 (n=5) idi, fakat üreterde rezidü taş fragmanı saptanan bir hastaya pos-operatif üreterorenoskopi uygulanarak bu oran %86 (n=6) ya yükseldi. Transfüzyon gerektiren kanama (Clavien derece 2) ve uzamış drenaj (Clavien derece 3a) olmak üzere iki hastada komplikasyon gelişti (%24). SonuçAt nalı böbrek anomalisi olan hastalarda PNL, normal anatomiye sahip böbreklerle kıyaslanabilecek kadar güvenli ve başarılı bir tekniktir. anahtar KelimelerAt nalı, böbrek, perkütan, nefrolitotomi, taş objective To share our experience in percutaneous nephrolithotomy (PCNL) procedures in patients with horseshoe kidney. Materials and MethodsThe data of 7 patients undergoing PCNL were analyzed retrospectively. Preoperative clinical and laboratory data of patients (including complete urinalysis, complete blood count, serum biochemistry, and coagulation tests) were recorded. The stone surface area (mm 2 ) was calculated by graph paper tracing of two dimensional projection of the stone on a plain film of the kidneys, ureters and bladder (KUB) in the anteroposterior view by investigators. In addition, per-operative and post-operative findings were evaluated. Success and complication rates (according to the classification of Clavien) were also determined. ResultsThe mean stone surface area was 1234 (range 250-2460 mm 2 ) mm 2 . Six patients were treated through a single tract, and one patient required additional access. Access was directed to the middle calyx (n=2), superior calyx (n=4), middle and inferior calyx (n=1) through the supracostal (n=2) and subcostal (n=5) areas. Mean operative time was 131 (range 70-215 minutes) minutes. Stone-free rate after single session PCNL was 71% (n=5) and increased to 86% (n=6) with a post-operative secondary ureterorenoscopy procedure. Complications including bleeding necessitating blood transfusion (Clavien grade 2) and prolonged drainage (Clavien degree 3a) were occurred in only 2 patients (24%). conclusionPCNL is a safe ...
