    Kidney transplantation in individuals with congenital skin fragility diseases is exceedingly uncommon due to perioperative concerns such as compromised wound healing, respiratory complications, and issues with vascular access. Herein, we report a case of successful living-donor kidney transplantation in a 37-year-old male with dystrophic epidermolysis bullosa and end-stage renal disease. Multidisciplinary planning, customized anesthesia, and protective intraoperative measures are essential to avoid these problems. Epidural anesthesia combined with mild sedation facilitated surgery without the need for airway instrumentation, while meticulous handling maintained skin integrity. The operation and recovery were unremarkable, and the graft function was maintained at 12 months. This case demonstrates that complex transplantation is achievable in environments with limited resources, through personalized perioperative treatment and interdisciplinary cooperation.

    Percutaneous nephrostomy is a first-line minimal invasive treatment option for ureteral obstruction following kidney transplantation, with high effectiveness and a low complication rate. Percutaneous nephrostomy might be used as a temporary salvage therapy, providing acute decompression of the kidney collecting system and preventing graft loss. It can also function as a permanent and sometimes only possible option in transplant patients with frequent recurrences of ureteral stenosis who either fail an open surgical reconstruction or who are not good candidates for these procedures. We present two patients with acute decline in urine output after renal transplantation with radiologically verified hydroureteronephrosis of the transplanted kidney (graft) caused by stenosis of distal ureter. In both cases, nephrostomy was placed within 48 hours as a temporary salvage treatment that ameliorates renal function and prevents graft loss. The permanent nephrostomy was the only possible solution for the preservation of the graft's function in the first case because of the recurrences of ureteral stenosis after several percutaneous interventions and open-surgery ureteral reconstruction. A few episodes of nephrostomy tube-related infections were resolved with antibiotics in the first case. The second case was treated with open ureteroneocystostomy with resection of stenotic segment and reinsertion of the ureter into the bladder (ureterocystoneostomy) because of the length of the involved ureteral segment. Both patients had stable graft function in the follow-up period.

    Obstructive uropathy encompasses various urinary tract obstructions, leading to changes in urine flow, kidney pressure, and impaired kidney function. Predicting renal recovery from obstructive uropathy, can be challenging and necessitates treatment, as in percutaneous nephrostomy (PNS) drainage. The choice of drainage method depends on patient-specific factors and local expertise. According to the data for the Republic of North Macedonia, in the register of the European Renal Association, in the last few years, there has been an increase in the percentage of patients with obstructive nephropathy from 7.6% to 8.9% who end up on a chronic hemodialysis program. Prompt relief from urinary tract obstruction is essential to preserve renal function and prevent complications. The aim of this study is to present our initial data analysis of recent experience in the use of nephrostomies as a method for temporary or long-term resolution of obstructive nephropathy, in terms of safety and success in preserving kidney function and reducing the number of patients on hemodialysis.

    Introduction: Hand-assisted laparoscopic living donor nephrectomy has become the technique of choice for living donor kidney donations. Since 2018, 30 procedures have been performed at our clinic using this technique. The goal of this comparative analysis was to determine how surgical technique, specifically, hand-assisted laparoscopic living donor nephrectomy with hand assistance may affect early graft function when compared to open classical nephrectomy. Material and methods: Retrospective analyses were performed, comparing the two techniques of kidney donation. Kidney transplantation was performed with the open standard technique in both groups. The primary outcome was early graft function, and levels of urine output, and plasma creatinine were analyzed at three time points. A secondary outcome was the quality of the operative technique, which was determined by the time of warm ischemia, blood loss, and duration of surgery. Additionally, we noted all complications, length of hospital stay, and patient satisfaction. Results: In terms of warm ischemia time, there was no statistically significant difference between donors in both groups. It is important to note that in 2 recipients from Group II we did not observe diuresis at the conclusion of the operation. The recipients' diuresis was 515 ml ± 321SD in group I and 444 ml ± 271SD in group II. At 3, 12, and 36 hours postoperatively, there were statistically significant differences in the average serum creatinine values (p 0.05) in favor of group I. Similar results were observed in the second time measurement at 12 h and the third time measurement at 36 h for serum urea levels in recipients. The difference in serum urea values between the recipients in the groups at the first measurement (3h) following surgery was not statistically significant. Conclusion: Hand-assisted laparoscopic donor nephrectomy is recognized as a safe and effective treatment. Donors in this situation have a different profile from other surgical patients; hence, they do not undergo surgery due to their own medical condition but for an altruistic reason, and with hand-assisted living donor nephrectomy. Such patients receive all the advantages of minimally invasive surgery. The two main objectives of a donor nephrectomy are to give the recipient the best possible kidney and to ensure the donor's complete safety.
