Tubeless Percutaneous Nephrolithotomy with Hemostatic Plug Using Surgiflo® versus Standard Percutaneous Nephrolithotomy using a Nephrostomy Tube: A Prospective Randomized Controlled Study

Background Percutaneous Nephrolithotomy (PCNL) is the preferred technique for treating large renal stones (over 2cm in diameter). It involves keyhole surgery performed through a small skin incision overlying the kidney. Objectives Our study aimed at evaluating the safety and efficacy of local hemostatic sealant (surgiflo®) use in tubeless PCNL to enhance postoperative outcomes of PCNL. Patients and Methods We randomized our patients into two groups, Group A nephrostomy tube was used as standard PCNL, and at group B tubeless PCNL was done followed by injection of the local hemostatic flowable gelatin matrix (surgiflo®) under fluoroscopic guidance in the prone position Results There was no statistically significant difference between two groups regarding demographic data age, sex and BMI (P- value 0.280, 0.736 and 0.440 respectively), stone site and size (P- value 0.525 and 0.533 respectively), operative time (P- value 0.855), intraoperative complications as blood loss and pelvicalyceal perforation, (P- value 0.92 and P- value 0.83 respectively), postoperative complication as fever, haematuria and UTI (P- value 1.000, 0,113 and 1.000 respectivly), and Hb drop (P- value 0.735). Conclusion Tubeless PCNL with hemostatic sealant use is associated with less pain, no leakage from nephrostomy tract, less narcotic agent use, and a shorter hospital stay.

A modern view on tubeless percutaneous nephrolithotomy

Urolithiasis ranks second among urological diseases, after inflammatory processes, and first among surgical interventions in urological hospitals. The problem of this disease treatment is a long-term rehabilitation and disablement, which entails a significant increase in costs and requires changes in the tactics of treatment of patients. Since its introduction until today, percutaneous nephrolithotomy (PCNL) is the standard treatment for nephrolithiasis with a stone size of more than 1.5–2.0 cm. In its standard version, PCNL ends with the placement of nephrostomy catheter through the formed parenchymal channel, but there are techniques of the surgery completion either without nephrostomy catheter with a JJ stent – tubeless PCNL, or without nephrostomy and JJ stent at all – totally tubeless PCNL. However, nowadays, the use of tubeless and totally tubeless techniques is one of the most controversial topics in percutaneous nephrolithotomy in terms of safety and efficacy in their application. Aim. To analyze the results and safety of percutaneous nephrolithotomy by means of tubeless and totally tubeless techniques based on scientific evidence. Analysis of the scientific literature shows that tubeless and totally tubeless PCNL techniques are a safe method of percutaneous surgery and their application reduces pain and analgesic requirements in the postoperative period, shortens the length of postoperative hospital stay, and enhances recovery after surgery in patients, therefore resulting in cost-saving treatment. Conclusions. Tubeless and totally tubeless PCNLs are recommended for widespread use in urological practice, but it is worth to mention that these techniques should be performed in selected patients and by an operating surgeon with significant experience in percutaneous surgery.

Supine tubeless PCNL in horseshoe kidney (a series of cases)

Objective: Objective of this case series is accurate access to the respective calyx with stone in horseshoe kidney while performing percutaneous nephrolithotmy in supine position. Reducing operative time and anaesthetic morbidity while performing percutaneous nephrolithotomy in horseshoe kidney with nephrolithiasis in supine position. Materials and Methods: Four patient with one having bilateral renal calculi with horshoe kidney were selected randomly. There were no preference for age, gender; size, location and laterality of stone or BMI. All the patients fit into the AUA guideline criteria for management by percutaneous nephrolithotomy. Preoperative, perioperative and follow up data were collected. Results: Four patients with one having bilateral renal calculi underwent supine tubeless PCNL in 1 year in GMSV position. There was no intraoperative, post operative or on follow up complications in any patient. In all the patients stones were cleared completely in single setting. Conclusion: Supine percutaneous nephrolithotomy in horseshoe kidney is an alternative to the standard prone percutaneous nephrolithotomy in the horseshoe kidney. It provides an additional benefit of performing the procedure in a single position, which is known to reduce total operating time, less anaesthesia related complications and less neuromusculoskeletal injury.

Percutaneous Nephrolithotomy: A Comparison of Tubeless versus the Standard technique

Objective: The proposed study aimed to assess the utility of tubeless PCNL in terms of efficacy and safety when compared with the standard tubed PCNL. Materials & Methods: In this study 280 patients (age ranged 08-70 years) who underwent PCNL were included. Results: The patients were from both genders i.e., 156 males and 124 females. Out of 280 patients, 140 had a 16 FR nephrostomy tube (Group A) whiles an equal number had 4.8F DJ Stent (Group B) for postoperative drainage. A comparison of the postoperative outcome among the two groups was made for a period of two years (November 2017 to October 2019). Neither any significant difference was found in the mean stone size, operative time, nor was stone-free status, nor any major complication observed. The mean hospital stay for group A and group B was 4.5 days (range 3 to 6) and 3.2 days (range 2 to 4) respectively. An early postoperative wound soakage was found in 18 (12.8%) cases of group A in contrast to the group B patients in whom only 2 (1.4%) had soakage. Conclusion: It was concluded that Tubeless PCNL as compared to the standard tubed PCNL was found more efficacious and safer and it should be adopted as a routine procedure.

Tubeless Supine Percutaneous Nephrolithotomy in Calyceal Diverticular Stone

Percutaneous Nephrolithotomy (PCNL) has routinely been performed in prone position as a treatment for calyceal diverticular stone. PCNL is performed supine as an alternate modality for calyceal diverticular stones. The objective of the procedure is to reduce operative time and anaesthetic morbidity during supine tubeless PCNL in calyceal diverticular stone. The series is about three patients with calyceal diverticular stones. These patients underwent supine tubeless PCNL in Galdakao modified supine Valdivia position. There was no intraoperative, postoperative or on follow-up complications in any of the the patients. In all the patients stones were cleared completely in single sitting. Supine PCNL in calyceal diverticular stone could be an alternative with similar outcomes to the standard prone PCNL. It provides an additional benefit of performing the procedure in a single position, which is known to reduce total operating time and also reduces anaesthesia complications.

Outcomes of Percutaneous Nephrolithotripsy With or Without Nephrostomy Tube: A Comparative Study

Introduction: Percutaneous Nephrolithotripsy (PCNL) is one of the most accepted surgical modality for removal of renal stone. Placement of a nephrostomy tube at the end of PCNL is a standard procedure for PCNL, however many reports have showed the safety and efficacy of tubeless PCNL for the removal of renal stone. Aims: The present study aimed to report the outcomes of PCNL with or without nephrostomy tube. Methods: It is Prospective Hospital Study conducted from June 2017 to April 2020 in the Department of Urology Nepalgunj Medical College. Total 153 patients under inclusion criteria were divided into two groups. Group 1 (75 patients) was allocated to patients who were being treated under standard PCNL procedure while Group 2 (78 patients) was allocated for patients who were being treated under Tubeless PCNL procedure. The two groups were compared for operation time (minutes), hospital stay (days), post operative dose of analgesic (mg), post operative complications such as, leakage (%), bleeding (%) and infection (%). Data were analyzed from SPSS and p-value less than 0.5 was considered as significant. Results: In Group II the mean hospital stay, analgesic dose and rate of leakage was significantly lesser than Group I (p<0.05) whereas, the mean operation time, rate of infection and bleeding were not significantly different between two groups (p>0.05). Conclusion: Tubeless PCNL procedure causes more rapid recovery and earlier discharge from the hospital, reduction in postoperative pain and no leakage when compared to standard tubless PCNL.
