York-Mason procedure for repair of recto-urinary fistulae: a 40-year experience

Study Type – Therapy (case series)

250 consecutive unilateral extravesical ureteral reimplantations in an outpatient setting.

PURPOSE Unilateral extravesical ureteral reimplantation is comparable to intravesical procedures and more effective than subureteral injection to resolve vesicoureteral reflux. Initial reports showed that the procedure could be feasibly done on an outpatient basis. We present further data on a large series of consecutive, planned, outpatient unilateral extravesical ureteral reimplantations. MATERIALS AND METHODS A total of 250 consecutive patients underwent scheduled outpatient unilateral extravesical ureteral reimplantation. We retrospectively reviewed their records. Patient data were collected on reflux laterality and grade, operative time, hospital stay, complications, need for rehospitalization and resolution rate on radiography 1 month postoperatively. RESULTS A total of 209 females (84%) and 41 males (16%) underwent planned outpatient extravesical ureteral reimplantation, including on the left side in 158 (63%) and on the right side in 92 (37%). Mean reflux grade was 3.2 with grades II to V in 64 (26%), 96 (38%), 74 (30%) and 16 cases (7%), respectively. Average operative time was 63 minutes and average length of stay, defined as time from initial admission in to discharge home, was 6.2 hours (range 3 to 10 hours). Short-term and late complications occurred in 9 (3.6%) and 8 patients (3.2%), respectively. CONCLUSIONS Extravesical ureteral reimplantation for unilateral vesicoureteral reflux may be consistently done on an outpatient basis with a reasonable complication rate and a low postoperative hospital admission rate.

Retrograde Percutaneous Access for Kidney Internal Splint Stent Catheter Placement in Pediatric Laparoscopic Pyeloplasty: Avoiding Stent Removal in the Operating Room

BACKGROUND AND PURPOSE Laparoscopic pyeloplasty has become increasingly used in the pediatric population for ureteropelvic junction (UPJ) obstruction. When choosing laparoscopic pyeloplasty, it is common to leave a Double-J ureteral stent across the anastomosis. In adult practice, this stent is easily removed in the office during follow-up; however, in pediatrics, cystoscopy and stent removal necessitates a trip back to the operating room. We report a novel method for placing a Kidney Internal Splint Stent (KISS) catheter, which can then be removed in the office during follow-up. METHODS The UPJ is dismembered, spatulated, and the new lateral edges are anastomosed as usual. With the renal pelvis still open, a STING needle is passed through the epigastric midline port. The laparoscope is used to visualize an appropriate posterior calix and direct the needle through the calix and out the back of the patient. A 7F vascular dilator is then threaded over the needle in retrograde fashion and into the collecting system. A 4F or 6F KISS catheter is then threaded through the dilator and down the ureter. The dilator is removed and the surgery is then finished according to the surgeons preference. RESULTS We have placed this catheter in nine children without difficulties or intraoperative complications. Mean age was 8 years. All stents were otherwise removed at an average of 13 days in the office without difficulty. Three patients had problems with intermittently poor drainage necessitating flushing; in one of these patients, a recurrence of the UPJ obstruction developed. CONCLUSION A laparoscopic approach for KISS catheter placement is a technically feasible and advantageous technique when placing a stent for a pyeloplasty repair. This eliminates a trip back to the operating room for stent removal in the pediatric population and likely decreases bladder irritation.

A Solitary Seminoma Renal Metastasis Presenting as an Incidental Renal Mass

A 34-year-old man with an extensive medical history received a CT scan for chronic leg and back pain. Imaging revealed a single, enhancing 8-cm mass in the upper pole of the right kidney. Laparoscopic radical nephrectomy was performed and pathologic finding revealed seminoma. Scrotal ultrasound and subsequent right orchiectomy also revealed seminoma. We discuss the occurrence of renal metastasis in seminoma.
