Advances in Peritoneal Dialysis

Continuous ambulatory peritoneal dialysis (PD) is one of the treatment methods used for end-stage renal failure. When mechanical complications occur with this treatment method, methods such as tomographic peritoneography, abdominal scintigraphy, and magnetic resonance peritoneography are used to uncover the problem. Here, we report the detection by tomographic peritoneography of a subcutaneous dialysate leak in a patient undergoing PD. The PD catheter was subsequently removed, and a new catheter was inserted...

Peritoneal dialysis (PD) is one of the treatment options for patients with end-stage renal failure. To start PD treatment, a catheter must be placed for access to the abdominal cavity, and it can be placed using surgical, laparoscopic, or percutaneous methods. However, complications can develop during catheter placement.In the present case report, we describe a patient in whom treatment was pursued after an unusual complication rarely mentioned in the literature: a dialysis catheter accidentally inserted percutaneously into the bladder...

In this retrospective study, the safety of initiating peritoneal dialysis (PD) immediately after percutaneous PD catheter insertion was evaluated. Patients who underwent peritoneal catheter insertion and then immediately began dialysis treatment were included in the study. Patient age, sex, treatment modalities, and method of catheter insertion were recorded.Acute PD was performed in 33 patients (age: 57.7 ± 16.7 years; 21 men, 12 women). Catheters were inserted percutaneously in 28 patients and surgically in 5 patients...

Exit-site infection poses a risk for peritonitis and can shorten peritoneal dialysis (PD) vintage. A loose fit of the skin around the catheter at the exit site can push bacteria surrounding the catheter into the subcutaneous tunnel. Negative-pressure wound therapy (NPWT) has been used to hasten healing of the wound after an operation or to treat pressure ulcers. We hypothesized that NPWT could speed the healing of the exit site and tighten the fit of the skin around the catheter. Using a V.A.C. Therapy system [vacuum-assisted closure (KCI, San Antonio, TX, U...

A 67-year-old white man with a history of end-stage renal disease receiving peritoneal dialysis (PD) presented with acute onset of vomiting, chills, and abdominal pain. He was diagnosed with PD-associated peritonitis secondary to Pasteurella. After failure of 3 weeks of antibiotic treatment, catheter loss occurred. On follow-up, the patient was found to have extensive intra-abdominal adhesions precluding placement of a new PD catheter.

Peritonitis is a major complication in peritoneal dialysis (PD) patients, often requiring a switch to hemodialysis (HD). Common sources of bacterial peritonitis are touch contamination and PD catheter-related infection. Intra-abdominal pathology is a less common cause of peritonitis in PD patients, and rarely is Neisseria mucosa the causative organism.We present an uncommon case of N. mucosa peritonitis in a 30-year-old African American female patient treated with nocturnal intermittent PD. The infection occurred in the setting of a translocated intrauterine contraceptive device (IUCD) in the infrahepatic region because of transmural migration...

To avoid loss of residual renal function (RRF) and to enhance solute clearance, we sometimes, from the initiation of peritoneal dialysis (PD) therapy, combine PD with hemodialysis (HD) that removes little or no fluid. In one typical valuable case, a 51-year-old woman with diabetic nephropathy who selected combined PD and HD therapy as her first dialysis method has continued on that therapy for 10 years. Her dialysis schedule consists of 5 PD days and 1 HD day without fluid removal weekly. Because this combination therapy was proactively started at dialysis initiation, good fluid control could be kept with urinary excretion and PD ultrafiltration...

Continuous ambulatory peritoneal dialysis (CAPD) is becoming increasingly known to the patients of Bangladesh, and patient numbers are increasing. Here, we report our experience and clinical outcomes in this field.Our analysis included all CAPD patients managed in a tertiary care hospital in Bangladesh between 2003 and 2015. All patients received a Tenckhoff double-cuff catheter by mini-laparotomy, and twin bags were used in most patients. In acute cases, regular exchanges were started manually with small-volume dwells the same or the next day...

Telehealth encompasses a broad variety of technologies and tactics to deliver virtual medical, health, and education services. Telemedicine is the use of electronic communications for the exchange of medical information from one site to another to improve a patient's clinical health status.Several studies show that, by providing better patient oversight and communication, telehealth in PD enhances patient care, outcomes, quality of care, and satisfaction. Associated benefits include increased patient retention to home dialysis, reduced use of hospital services, and reduced costs of care...

The aim of the present study was to compare the aortic systolic blood pressure (aSBP), heart-rate-adjusted augmentation index (AIx75 ), and pulse wave velocity (PWV) obtained using the Mobil-O-Graph (IEM, Stolberg, Germany) and SphygmoCor (AtCor, Sydney, Australia) devices in patients receiving peritoneal dialysis (PD).After a 10-minute rest in the supine position, the Mobil-O-Graph and SphygmoCor devices were applied in randomized order in 27 consecutive PD patients. The agreement between the measurements produced by the Mobil-O-Graph and SphygmoCor devices was explored using Bland-Altman analysis...

Compared with hemodialysis (HD), peritoneal dialysis (PD) is associated with reduced cost and improved quality of life. But despite those benefits, PD represents a small percentage of the renal replacement therapy performed. Although a number of factors contribute to that situation, peritoneal drop-out is a complex issue that leads to as much as a 35% annual transition from PD to in-center HD. The reasons for drop-out are multifaceted and include contributions from the patient or caregiver, health care regulatory systems, and factors intrinsic to the PD modality...

Peritoneal dialysis (PD) dosing is determined by urea clearance scaled to total body water (TBW). However, studies delivering greater peritoneal Kt/V urea have failed to demonstrate improved survival. Body surface area (BSA) has been suggested as an alternative scaling factor. Cellular metabolism generates toxins, and thus total energy expenditure (TEE) might be a preferable scaling factor. Because TEE is cumbersome to determine, we set out to determine the association of anthropomorphic scaling factors with TEE...

Urea kinetics (weekly Kt/V) greater than 1.7 generally define adequate peritoneal dialysis (PD). Adequacy of PD depends on residual renal function and PD clearance. Preserving residual renal function and peritoneal membrane characteristics helps to maintain PD adequacy.The dose of PD can be augmented by increasing the total dialysate volume. Greater volume can be achieved by increasing either the fill volume per exchange or the number of exchanges. Increased time on dialysis can be achieved by keeping PD fluid in the peritoneal cavity at all times...

The effects of medium- or long-term use of neutral-pH dialysate on peritoneal transport and peritoneal damage have not been sufficiently researched.We retrospectively evaluated time-dependent changes in the dialysate-to-plasma ratio of creatinine (D/P Cr) and biomarkers of peritoneal damage in the effluent of 65 patients who underwent peritoneal dialysis (PD) with neutral-pH dialysate, including 48 who underwent medium-term PD (≥3 years) and 17 who underwent long-term PD (≥5 years).Patients who underwent medium-term PD initially had a D/P Cr of 0...

Adequate nutrition and growth is vital in pediatrics. Breast milk alone might not be able to satisfy the nutrition needs of an infant with renal disease. Similac PM 60/40 (Abbott Laboratories, Abbott Park, IL, U.S.A.) is a low-iron infant formula indicated for infants who would benefit from a lowered mineral intake. It is the only infant formula marketed in the United States for infants with renal impairment. The objective of the present case study was to examine whether Renastart, a pediatric renal formula (Nestlé Health Science, Florham Park, NJ, U...

Peritoneal dialysis (PD) and hemodialysis (HD) combination therapy is considered for the improvement of ultrafiltration failure and uremic symptoms in PD patients with loss of residual renal function (RRF). However, a rapid decline in RRF is one of the critical drawbacks to such therapy. In contrast, we started patients on combination therapy as a proactive option at the initiation of dialysis.In patients on HD (n = 52), PD (n = 21), and combination dialysis (n = 13), we studied changes in RRF, blood parameters, and peritoneal permeability for 30 months...

Peritoneal dialysis (PD) is recognized as an excellent method of dialysis because the therapy is gentle, continuous, and cost-effective. However, a large number of patients must unfortunately transfer from PD to hemodialysis because of peritonitis or fluid overload in the early phase after PD initiation. In the present study, we reviewed clinical indicators before PD initiation to try to identify predictive factors for early withdrawal from PD.For this retrospective cohort study at two hospitals between March 2003 and October 2016, we defined withdrawal from PD as the induction of combination therapy, transfer to hemodialysis, or death...

Healing Touch therapies use a practitioner's intentional placement of hands to influence the patient's energy fields to promote self-healing. In the changing climate of health care, in which the patient experience increasingly drives reimbursements, it is vital to find unique and meaningful ways beyond traditional medical therapies to ensure positive patient experiences. To that end, our peritoneal dialysis clinic staff adopted Jean Watson's theoretical framework, by which patients are treated as whole unique individuals with a "multidimensional system of energy, with a consciousness that can be affected by another to promote well-being...

Peritoneal dialysis (PD) is an umbrella term that encompasses a variety of techniques such as continuous ambulatory PD, automated PD, tidal PD, and intermittent PD, among others. The various techniques exist to tailor the PD prescription to meet the goals of individual patients. Various clinical and nonclinical factors can change over time, requiring a change to the PD prescription. This article uses a practical case study to highlight the intricacies of the calculations behind PD prescription to achieve clearance goals...
