About Dr. Diwakar Naidu Gajjala
Dr. Diwakar Naidu Gajjala is a consultant nephrologist at KIMS Institute of Renal Sciences & Advanced Urology, Secunderabad, with specialist expertise across the full range of dialysis modalities, renal transplant care, critical care nephrology, and interventional nephrology procedures. He joined KIMS in September 2014 after completing his DM in Nephrology at NIMS, Hyderabad.
His academic path ran from MBBS at Kurnool Medical College through MD in General Medicine at SVRR Government General Hospital, Tirupati, before his DM in Nephrology at Nizam's Institute of Medical Sciences (NIMS), Hyderabad — the central government's premier postgraduate institution in the state and the regional reference centre for nephrology training. NIMS Nephrology exposes trainees to the highest volume and complexity of kidney disease in Telangana, including ABO-incompatible transplant, complex glomerulonephritis management, and every form of renal replacement therapy.
Before joining KIMS, Dr. Gajjala worked as a junior consultant in internal medicine and critical care at CARE Hospital, Banjara Hills — giving him a strong critical care foundation alongside his nephrology training — and as a consultant nephrologist and renal transplant physician at Prathima Hospitals, Kukatpally. That combination of critical care background and nephrology superspecialty training directly shaped his expertise in critical care nephrology (CRRT, SLED) and in the procedural side of nephrology — CVP insertion, PD catheter insertion, tunnelled permacath placement, fistulogram assessment, and renal biopsy.
During his DM training he co-authored a publication on Peritoneal Equilibration Test data from a single Indian centre in the Indian Journal of Nephrology (March 2013) — reflecting an academic engagement with peritoneal dialysis that complements his clinical work in PD.
Areas of clinical expertise
Dialysis modalities — the complete spectrum
Dr. Gajjala is proficient across the full range of renal replacement therapy modalities available at KIMS — the broadest modality range in the KIMS nephrology team, including SLED and haemoperfusion in addition to standard HD, PD and CRRT.
- Haemodialysis (HD) — acute and maintenance HD, adequacy assessment (Kt/V), high-flux and low-flux dialysis, and haemodiafiltration (HDF) for enhanced clearance
- Peritoneal dialysis (CAPD and CCPD) — prescription, adequacy monitoring including the Peritoneal Equilibration Test (PET), exit-site care and peritonitis management; PD catheter insertion, percutaneous and surgical
- CRRT (continuous renal replacement therapy) — for AKI in the ICU. CVVH, CVVHD and CVVHDF modes, anticoagulation protocol, filter lifetime management
- SLED (sustained low-efficiency dialysis) — a hybrid modality combining elements of HD and CRRT, particularly useful in haemodynamically unstable ICU patients who cannot tolerate standard HD
- Plasmapheresis (PLEX) — therapeutic plasma exchange for antibody-mediated conditions: anti-GBM disease (Goodpasture's), ANCA vasculitis, TTP and antibody-mediated rejection
- Haemoperfusion — adsorption-based blood purification for toxin or cytokine removal, used in certain drug toxicities, sepsis-related cytokine storm, and liver failure support
Interventional nephrology
- CVP (central venous pressure) catheter insertion — subclavian, internal jugular and femoral approaches for temporary dialysis access
- PD catheter insertion — percutaneous and surgical peritoneal dialysis catheter placement
- Tunnelled permacath placement — long-term dialysis access catheter insertion
- Renal biopsy — percutaneous ultrasound-guided native and transplant kidney biopsy
- Fistulogram assessment — evaluation of an AV fistula or AV graft for access dysfunction, stenosis or thrombosis, with coordination with vascular surgery for intervention
Renal transplant
Pre-transplant recipient medical evaluation, post-transplant immunosuppression management, diagnosis and treatment of rejection (both cellular and antibody-mediated), and management of transplant complications — infection (CMV, BK virus, opportunistic infections), post-transplant hypertension, and CKD in the transplanted kidney.
Critical care nephrology
Acute kidney injury evaluation and management in the ICU — multi-organ failure, sepsis-associated AKI, cardiorenal syndrome and hepatorenal syndrome. CRRT and SLED initiation and prescription, with coordination alongside the KIMS critical care team for dialysis in ventilated patients.
Stone disease — medical management
Medical management of urinary stone disease — determining stone type (uric acid, calcium oxalate, calcium phosphate, struvite, cystine), metabolic workup, and dietary and pharmacological prevention, with coordination with the KIMS urology team for surgical stone management.
