    Background Nephroptosis is a clinical condition characterized by symptoms related to an abnormal caudal movement of the kidney. During the past decade, the availability of laparoscopic surgery has led to a revival of interest in nephroptosis. Most of the traditional surgical techniques aim to achieve kidney fixation by placing triangulation sutures between the abdominal wall and the renal capsule. These sutures are often difficult to tie because of the confined working space. Case Presentation We herein present a case of a 31-year-old female patient who presented with symptomatic right-sided nephroptosis and was managed effectively by laparoscopic nephropexy. We have applied a technical modification to facilitate laparoscopic fixation by utilizing suture and nonabsorbable polymer clips (“sliding clip” technique). ZK-62711 Conclusion Laparoscopic nephropexy is a safe and effective procedure for the management of symptomatic nephroptosis. The “sliding clip” technique is a modification familiar to most urologists that facilitates intracorporeal suturing and adequate renal fixation.Background Recently, two techniques of robot-assisted radical prostatectomy (RARP), which preserve dorsal vein complex (DVC), endopelvic fascia, and full neurovascular bundle (NVB), through anterior approach were reported. The techniques in a relatively large workspace seem less technically demanding than Retzius-sparing RARP. In this case report, we present a further modified technique of transperitoneal-anterior-antegrade approach with a division of the endopelvic fascia to reduce the technical demands. Case Presentation In a routine evaluation, a 65-year-old man was shown to have a prostate-specific antigen level of 5.07 ng/mL. Prostatic biopsy revealed a Gleason score of 6 (3 + 3) adenocarcinoma in 2 of the 12 specimens, and the clinical stage was diagnosed as cT2aN0M0. RARP was performed including transperitoneal full NVB sparing, antegrade preservation of DVC, and division of endopelvic fascia to increase the prostate mobility and reduce technical demands. The patient completely gained continence on the day after removal of the catheter, and potency was recovered 30 days after surgery. Conclusion Our DVC preservation technique in the transperitoneal-anterior-antegrade approach with a division of the endopelvic fascia during RARP may be safe, reduce technical demands, and facilitate early recovery of continence and sexual function after surgery.Background Forgotten ureteral stent is frequently observed in urologic practice. It has serious consequences such as encrustation, stone formation, fragmentation, ureteral damage, and sepsis. Panureteral damage by forgotten stent is a major complication requiring complex reconstructive surgery. Case Presentation We report a case of 66-year-old man with forgotten ureteral stent for 10 years, which caused panureteral damage. Ileal ureteral substitution was done and kidney was salvaged. Conclusion Prolonged forgotten stent can cause panureteral fibrosis and requires complex surgical procedure such as ileal ureteral substitution.Introduction Congenital ureteral valves are a rare cause of ureteral obstruction that may lead to renal function deterioration. We present two clinical cases treated endoscopically by monopolar electrocautery and laser fiber ablation. Presentation of Case The first case is a 13-year-old male with several episodes of abdominal pain and was found to have severe left hydronephrosis. Ultrasonography showed a dilated ureter and pelvicaliceal system with an obstructive renogram curve. We performed a retrograde pyelogram, finding a dilated ureter 5 cm up from the vesicoureteral junction with ureteral valves in that place. Ablation of the valves was conducted using monopolar electrocautery. The second case is a 2-year-old male with left ureterohydronephrosis shown in abdominal ultrasonography. In the radiologic findings, a high-risk pyelocaliceal dilatation with renal parenchyma thinning and a diameter of 3.3 cm for the left ureter is described, with an obstructive renogram. We performed a cystoscopy, observing the presence of valves in the ureter at 3 cm that conditioned an obstruction. The complete section of the valves was performed through a 270μm holmium laser fiber. Our patients made an uneventful postoperative recovery and continue to remain completely asymptomatic. A significant decrease in renal dilation was observed and renal function recovered in both cases. Conclusion Ureteral valves are an uncommon cause of ureteral obstruction. Advances in endourologic techniques allow us to give a minimally invasive approach to these diseases, obtaining good long-term results in our small series of patients.Background Crossed fused renal ectopia (CFRE) is an unusual anomaly in which both kidneys lie fused on one side, with double pelvis and ureters draining into both sides of the bladder. Complex renal stones are a considerable challenge to endourologists, and when a staghorn stone is associated with abnormal anatomy, its treatment is even more difficult. Today there is no consensus about the right treatment for complex renal stones in CFRE. So, the objective of this case is to present the efficacy of the endoscopic combined intrarenal surgery (ECIRS) for the treatment of a staghorn renal stone in one patient with CFRE. Case Presentation We described a case of a 23-year-old man with prolonged lasting and pain on the left flank associated with intermittent gross hematuria. Enhanced CT revealed a crossed fused kidney on the left side, drained by an intercommunicating pelvis and a single ureter, with a staghorn stone wholly occupying both renal units. The patient was effectively treated by one single session of ECIRS. Conclusion The ECIRS is a good alternative to consider in patients with CFRE that have a staghorn calculus with a reasonable success rate.Background Percutaneous nephrostomy (PCN) is commonly indicated for upper urinary tract drainage in case of obstruction or fistula. Only a few cases of PCN catheter misplacement into the inferior vena cava (IVC) have been published. Case Presentation We report a case of a PCN catheter misplaced into the IVC through a fistula between the urinary tract and an ipsilateral renal vein in a patient with horseshoe kidney, after bedside urgent replacement for hemorrhage and hemorrhagic shock. Conclusion Although a nephrostomy Foley catheter can be used for adequate urinary drainage and hemostatic purposes after percutaneous nephrolithotomy, its placement should be always verified through antegrade pyelography and particular care should be used for horseshoe kidneys. In case of massive hemorrhage, after temporary closure of the PCN catheter, the cause of bleeding should be investigated with urgent angiography or contrast-enhanced CT scan and promptly treated.
