The Wound Care Surveillance Program has been a very effective strategy for the prevention and management of pressure ulcers. Stage two ulcers were the most common in our setup. Braden scoring, traditionally used to screen these ulcers, can be used as a predictive and prognostic tool to predict healing of pressure ulcers. Poor healing is expected in higher staged ulcers and patients with spinal injury and major solid organ injury and those who need a tracheostomy. Home-based care is not up to mark in our society and accounts for most of the cases in the follow-up.

Introduction:Percutaneous nephrolithotomy (PCNL) for stones in solitary kidney poses a significant challenge and potential threat for acute kidney injury or progression of chronic kidney disease (CKD). We present our experience of PCNL in solitary functioning kidney (SFK) to evaluate the safety, efficacy, and postoperative complications and highlight the differences between these outcomes with respect to the stage of CKD.Methods:We carried out a retrospective study of patients with SFK, who underwent PCNL at our center from April 2010 to March 2018. Patients who had a minimum of 6 months of follow-up were included. Patients were classified into CKD groups based on the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative. Group 1 included Stages 1, 2, and 3A and Group 2 included Stages 3B, 4, and 5. Postoperative complications and stone-free rate were recorded and graded according to the Clavien–Dindo classification and compared between the two groups.Results:We had a total of 128 patients (Group 1 – 84 and Group 2 – 44). Stone-free rate after the first PCNL was higher in Group 1 as compared to Group 2 (88.1% [n = 74] vs. 50% [n = 22], P = 0.02). Overall, 48 patients (37.5%) had postoperative complications, but most were minor. Clavien Grade 1 and 2 complications were seen in 34 patients (Group 1, n = 18 and Group 2, n = 16, P = 0.069), whereas Grade 3 and 4 complications were seen in 14 patients (Group 1, n = 2 and Group 2, n = 12, P < 0.001), respectively. Need for postoperative (number of sessions) dialysis was seen with increased frequency in patients with higher chronic kidney stages (Group 1 vs. Group 2; 6 vs. 22 sessions, P < 0.001).Conclusion:PCNL in SFK is safe, with satisfactory outcome, but patients with advanced CKD stage have higher risk of complications including need for dialysis and may require multiple sessions for complete stone clearance. Hence, they should be managed at high output tertiary centers.

Objective: (a) To assess the inter-observer variability amongst surgeons performing percutaneous nephrolithotomy (PCNL) and radiologists for the Guy's Stone Score (GSS) and S.T.O.N.E. (stone size [S], tract length [T], obstruction [O], number of involved calyces [N], and essence or stone density [E]) nephrolithometry score; (b) To determine which scoring system of the two is better for predicting the stone-free rate (SFR) after PCNL. Patients, subjects and methods: Patients undergoing PCNL between February 2016 and September 2016 were prospectively enrolled. Preoperative computed tomography was done in all patients. The GSS and S.T.O.N.E. nephrolithometry score were independently calculated by eight surgeons and four radiologists. The patients were operated on by one of the surgeons (all were consultants). The Fleiss' κ coefficient was used to assess agreement independently between the surgeons and radiologists. Receiver operating characteristic (ROC) curves were constructed for predicting the SFR using the average of the scores of the surgeons and radiologists separately. Results: A total of 157 patients underwent PCNL. The SFR was 71.3% (112/157 patients). The Fleiss' κ scores ranged from 0.51 to 0.88 (overall 0.79) for the S.T.O.N.E. score and 0.53-0.91 for the GSS, suggesting moderate to very good agreement. The ROC curve for the S.T.O.N. E. nephrolithometry scores of surgeons (area under the curve [AUC] = 0.806) as well as the radiologists (AUC = 0.810) had a higher predictive value for the SFR than the GSS of the surgeons (AUC = 0.738) and the radiologists (AUC = 0.747). Conclusion: There is overall good agreement between surgeons and radiologists for both the GSS and S.T.O.N.E. nephrolithometry score. The S.T.O.N.E. score had a higher predictive value for the SFR than the GSS.
