BACKGROUND
Hemorrhage is a common complication of nephrostomy and percutaneous nephrolithotripsy, and it is caused by surgical factors. Here we report a rare case of hemorrhage caused by sepsis-related coagulation dysfunction.
CASE PRESENTATION
A 72-years-old male patient with bilateral ureteral calculi accompanied by hydronephrosis and renal insufficiency developed sepsis and hemorrhage on the third day after bilateral nephrostomy. After vascular injury was excluded by DSA, the hemorrhage was considered to be sepsis-associated coagulopathy(SAC/SIC), finally the patient recovered well after active symptomatic treatment.
CONCLUSIONS
In patients with sepsis and hemorrhage, SAC/SIC cannot be excluded even if coagulation function is slightly abnormal after surgical factors are excluded. For urologists who may encounter similar cases in their general urology practice, it is important to be aware of these unusual causes of hemorrhage.

Review
Nephron sparing surgery (NSS) is considered for selected cases of upper tract urothelial carcinoma (UTUC) as it maintains renal function and avoids morbidity associated with radical nephroureterectomy (RNU). The appropriate selection of patients suitable for NSS without compromising oncological outcomes can sometimes be difficult, given the limitations of diagnostic modalities. Recurrence rates for UTUC can be as high as 36 to 54% after NSS. Intraluminal adjuvant therapy can be attempted following NSS to reduce recurrence, but delivery to the upper tract is more challenging than into the bladder. Bacillus Calmette-Guerin (BCG) and chemotherapy such as Mitomycin (MMC) have been administered via nephrostomy or ureteric catheter, which requires invasive/repeated instrumentation of the upper urinary tract. Drug delivery by reflux from bladder instillation along indwelling stents has also been tried but can potentially be unreliable. Recently, a gel formulation of mitomycin has been developed for the controlled exposure of the upper urinary tract to treatment over a number of hours. Drug-eluting stents to deliver chemotherapy to the upper urinary tract have been developed but have not yet entered clinical practice. Endoluminal phototherapy utilising an intravenous photosensitising agent is another novel approach that has recently been described. Intraluminal therapies may be beneficial in decreasing recurrence rates in UTUC, but currently have some limitations in their usage.

INTRODUCTION
Despite the growing number of patients requiring kidney replacement therapy (KRT), peritoneal dialysis (PD) is underutilized globally. A contributory factor may be clinician myths about its use. The aim of this study was to explore perceptions about PD initiation by clinicians according to various physical, social, and clinical characteristics of patients.
METHODS
An online global survey (in English and Thai) was administered to ascertain nephrologists' and nephrology trainees' decisions on recommending PD as a treatment modality.
RESULTS
A total of 645 participants (522 nephrologists and 123 trainees; 56% male) from 54 countries (66% from high-income countries [HICs], 22% from upper middle-income countries [UMICs], 12% from lower middle-income countries, and 1% from low-income countries [LICs]) completed the survey. Of the respondents, 81% identified as attending physicians or consultants, and 19% identified as trainees or other. PD was recommended for most scenarios, including repeated exposures to heavy lifting, swimming (especially in a private pool and ocean), among patients with cirrhosis or cognitive impairment with available support, and those living with a pet if a physical separation can be achieved during PD. Certain abdominal surgeries were more acceptable to proceed with PD (hysterectomy, 90%) compared to others (hemicolectomy, 45%). Similar variation was noted for different types of stomas (nephrostomies, 74%; suprapubic catheters, 53%; and ileostomies, 27%).
CONCLUSION
The probability of recommending PD in various scenarios was greater among clinicians from HICs, larger units, and consultants with more clinical experience. There is a disparity in recommending PD across various clinical scenarios driven by experience, unit-level characteristics, and region of practice. Globally, evidence-informed education is warranted to rectify misconceptions to enable greater PD uptake.

Gaceta Medica de Mexico 2024Percutaneous nephrostomy tubes (PNT), which are used in some cancer hospitals, are associated with an increase in urinary tract infections (UTI).
INTRODUCTION
Percutaneous nephrostomy tubes (PNT), which are used in some cancer hospitals, are associated with an increase in urinary tract infections (UTI).
OBJECTIVE
To determine the impact of a standardized care program on the incidence of UTIs requiring hospitalization (UTI-RH).
MATERIAL AND METHODS
Retrospective study that included patients with a first PNT inserted. The incidence, relative risk (RR), costs and outcomes of patients with UTI-RH were compared during the period before (P0) vs. after the intervention (P1).
RESULTS
113 PNTs were inserted during P0, and 74 at P1. During P0, 61 patients (53.9%) experienced 64 UTI-RH events in 22,557 PNT days. At P1, four patients (5.4%) had a UTI-RH in 6,548 PNT days (IRR: 0.21, 95% CI: 0.05-0.57). The RR was 0.09 (95% CI: 0.03-0.25). Monthly cost per day/bed was USD 3,823 at P0 and USD 1,076 at P1, and for antibiotics, it was USD 790 at P0 and USD 123.5 at P1.
CONCLUSIONS
This study highlights the importance of a standardized care program for permanent percutaneous devices, since this reduces antibiotic use, hospitalization, and the cost of care.

Review
OBJECTIVE
To systematically summarise the current clinical evidence for de novo malignant upper urinary tract obstruction treatment with a focus on standards of reporting, patient outcomes and future research needs.
METHODS
This review protocol was published via PROSPERO (CRD42022341588). OVID MEDLINE (R), EMBASE, Cochrane Central Register of Controlled Trials-CENTRAL were searched up to June 2022 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses. Prospective and retrospective studies were included.
RESULTS
Of 941 articles identified, 82 with 8796 patients were eligible for inclusion.Most studies in the published literature are retrospective and investigate heterogenous malignancies. Percutaneous nephrostomy and ureteric stenting are the most studied interventions. Few studies describe the outcomes from no intervention or investigate patient perspectives. Overall reported median survival after intervention was around 11.7 months. A lack of standardised reporting of outcomes was evident.
CONCLUSIONS
Malignant upper urinary tract obstruction is an important clinical condition affecting patients globally. Overall survival after intervention appears poor however the current evidence base has significant limitations due to studies of low methodological quality and the lack of a standardised framework for reporting outcomes.We have provided a pragmatic framework for future studies based on the review to ensure a uniform methodology is utilised moving forward.

Frontiers in Surgery 2024Malignant peritoneal mesothelioma (MPM) is an extremely rare tumor with nonspecific clinical manifestations, making diagnosis challenging.
INTRODUCTION
Malignant peritoneal mesothelioma (MPM) is an extremely rare tumor with nonspecific clinical manifestations, making diagnosis challenging.
CASE PRESENTATION
Herein, we report a case of MPM with occult onset presenting with bilateral hydronephrosis and renal insufficiency. A 30-year-old man was admitted to the Urology Department because of recurrent bilateral lower back pain. The etiology was unclear after a series of laboratory tests, imaging examinations, bone marrow aspiration, renal puncture biopsy, ascites examination, ureteroscopy, and so on. Finally, MPM was diagnosed by laparoscopic exploration and biopsy. Moreover, during the course of the disease, the patient's bilateral ureters were compressed, and the obstruction could not be relieved after the placement of ordinary ureteral stents. Percutaneous nephrostomy or metal ureteral stenosis was appropriate in managing malignant ureteral obstruction as it could improve renal function.
CONCLUSIONS
The onset of this case was insidious, and the diagnosis was difficult, with a poor prognosis. To date, only a handful of cases have been reported. We hope this case can provide some enlightenment for our clinical work.

Archivio Italiano Di Urologia,... May 2024In this study, the aim was to compare the results of mini and standard percutaneous nephrolithotomy (PCNL) for the treatment of pediatric kidney stones.
OBJECTIVE
In this study, the aim was to compare the results of mini and standard percutaneous nephrolithotomy (PCNL) for the treatment of pediatric kidney stones.
MATERIALS AND METHODS
Data for 128 patients < 18 years of age who underwent mini and standard PCNL due to pediatric kidney stones were retrospectively examined. Patients were divided into two groups: mini-PCNL (16-20 Fr) and standard PCNL (26 Fr). Surgery time, number of punctures to the pelvicalyceal system, hospital stay, postoperative hemoglobin drop, complications and stone-free status (SFR) were compared between the groups. Additional surgical intervention (double-J stent, ureterorenoscopy, secondary PCNL) performed after the surgery was recorded. The absence of residual stones or < 3 mm residual stones on kidney, ureter and bladder radiography (KUB) and ultrasonography (USG) performed in the third postoperative month were accepted as success criteria.
RESULTS
There were 32 (43.8%) patients in the mini-PCNL group and 41 (56.2%) patients in the standard PCNL group. The mean age was 9.3 ± 4.1 years in the mini-PCNL group and 10.1 ± 5.4 years in the standard PCNL group. Mean stone size in the mini-PCNL group was 2.1 ± 1.2; while for standard PCNL it was 2.3 ± 1.4. The mean surgery time was statistically significantly higher in the mini-PCNL group (p = 0.005). There was no difference between the groups in terms of intraoperative double J stent use, postoperative complications and SFR. A double J stent was inserted in two patients in the mini-PCNL group and in one patient in the standard PCNL group due to urine leakage from the nephrostomy tract in the postoperative period. Although the postoperative hemoglobin drop was found to be significantly higher in standard PCNL (p = 0.001), hematuria and blood transfusion rates were low in both groups. Mean hospital stay was shorter in the mini-PCNL group compared to standard PCNL (3.6 ± 1.2 days vs. 2.5 ± 1.1; p = 0.018).
CONCLUSIONS
Although mini-PCNL has longer surgery time compared to standard PCNL, it should be preferred for the treatment of pediatric kidney stones due to advantages such as similar success and complication rates to standard PCNL, short hospital stay and less postoperative hemoglobin drop.

IJU Case Reports May 2024We report a case of megaureter in a functional solitary kidney in which surgery was performed after bladder capacity was increased by home bladder cycling.
INTRODUCTION
We report a case of megaureter in a functional solitary kidney in which surgery was performed after bladder capacity was increased by home bladder cycling.
CASE PRESENTATION
A 6-day-old girl with a left megaureter, a right multicystic dysplastic kidney, and bladder hypoplasia underwent percutaneous left nephrostomy for obstructive renal failure. At 8 months, home bladder cycling was initiated to increase bladder capacity before the planned ureterocystoneostomy. Surgery was performed after bladder capacity increased. The left ureter was compressed by the left umbilical ligament, so ureteral end-to-end anastomosis was performed at 1 year and 4 months. At 2 years and 8 months, cystometry showed age-appropriate bladder capacity and improved bladder compliance.
CONCLUSION
To the best of our knowledge, this is the first report of bladder hypoplasia treated by home bladder cycling.

The uncommon but dangerous condition known as emphysematous pyelonephritis (EPN) usually affects people with diabetes. This potentially fatal illness is characterized by gas-forming necrosis of the kidneys and surrounding tissues, typically brought on by urinary tract bacteria. Fungal EPN, less prevalent than bacterial EPN, has been reported in a few isolated cases. Cultures of the urine or blood often detect the infection. With an 18% fatality rate, EPN is still a serious illness despite advancements in therapy. High suspicion for EPN is critical in diabetic patients experiencing pyelonephritis. Interestingly, women with uncontrolled diabetes seem to be more susceptible. While is the usual culprit, rare cases involve species. This case report describes a pathogen that is rarely encountered and causes EPN. A diabetic woman in her sixties without prior hospitalizations presented with a sudden fever and excruciating abdominal pain. The patient also complained of abdominal distension with reduced urine output and breathlessness at rest. Investigations revealed left-sided EPN that was "WAN Type 1." We treated the patient according to culture sensitivity with systemic antifungals, percutaneous nephrostomy (PCN), and ureteral stenting (double J stent or DJ stent). Following successful treatment, the patient recovered and was discharged. This case highlights the importance of considering uncommon causes, even in seemingly typical presentations of EPN. Our case is unique as the patient had an infection with non-albicans Candida with a complication of anuric acute kidney injury and uncontrolled diabetes mellitus.

Review
OBJECTIVE
To assess if there is a preferable intervention between retrograde ureteral stent (RUS) and percutaneous nephrostomy (PCN) tube, in cases of upper urinary tract stone obstruction with complications requiring urgent drainage, by evaluating outcomes regarding urinary symptoms, quality of life (QoL), spontaneous stone passage, and length of hospital stays, since there is no literature stating the superiority of one modality over the other.
METHODS
We searched MEDLINE and other sources for relevant articles in June 2019 without any date restrictions or filters applied. The selection was done first by the title and abstract screening and then by full-text assessment for eligibility. Only randomized controlled trials or cohort studies in patients with hydronephrosis secondary to obstructive urolithiasis that presented comparative data between PCN and RUS placement concerning at least one of the defined outcome measures were included. Lastly, MEDLINE database and PubMed platform were screened again using the same terms, from June 2019 until November 2022.
RESULTS
Of 556 initial articles, seven were included in this review. Most works were considered of moderate-to-high quality. Three studies regarding QoL showed a tendency against stenting, even though only one demonstrated statistically significant negative impact on overall health state. Two works reported significantly more post-intervention urinary symptoms in stenting patients. One article found that PCN is a significant predictor of spontaneous stone passage, when adjusted for stone size and location. Findings on length of hospital stays were not consistent among articles.
CONCLUSION
PCN appears to be the intervention better tolerated, with less impact on the patient's perceived QoL and less post-operative urinary symptoms, in comparison with RUS. Nevertheless, further studies with larger samples and a randomized controlled design are suggested.
