Introduction. Anatrophic nephrolithotomy is a procedure in which a parenchymal incision is made in an intersegmental plane, allowing removal of large renal. We offered the patient staged open anatrophic nephrolithotomy. Results. Operative time was minutes. Blood loss was cc. requiring one. The anatrophic nephrolithotomy described by Smith and Boyce is an excellent method of preserving a maximum number of functioning nephrons by minimizing .

Laparoscopy is needed in complex staghorn stones that would necessitate multiple, simultaneous or subsequent, percutaneous renal accesses [ 3 — 10 ].

The mean operative time was minutes and mean cold ischemia time was Ischemic injury may also arise if there is inadvertent injury to major vessels, although, it is not so common. Guidelines from American Urological Association and European Urology Association state that conventional excision of staghorn stones must be considered only in exceptional cases and that percutaneous nephrolithtomy PNL should be the preferred choice[ 12 ].
Renal function improvement may occur after stone treatment. The main steps in this procedure are: Stone-free status of the left kidney was confirmed after surgery with CT scan. In our experience, open surgery still plays a role in the treatment of staghorn stone disease, even if rarely required. European Association of Urology Guidelines.
Total operative time was minutes. Even if anatrophic nephrolithotomy is currently performed laparoscopically, in patients affected by severe cardiac or pulmonary diseases or with a previous laparotomy, laparoscopic approach may not be indicated. The subsequent introduction of laparoscopic approach has almost eliminated the need for open operations in the treatment of renal and ureteral stones.

Belis et al [ 15 ]. Pneumatic lithotripsy through pyelotomy incision during open surgery for staghorn calculi: Surgical management of nephrolithiasis has changed dramatically in the last few decades. Nevertheless in our experience, open surgery still represents the treatment of choice in rare cases. The collecting system was opened and the stones were exposed. In the last few decades, surgical approach to stone treatment has changed dramatically. Procedures with low morbidity and rapid recovery are also essential in current practice.
This article is an open-access article which was selected by an in-house editor and fully peer-reviewed by external reviewers.
The calculi are extracted, which may require incising stenotic infundibula to facilitate removal. Ureter was then looped and dissection at hilum was done to identify renal artery, vein and then the posterior segmental artery. El-Tabey et al[ 34 ] found that multiple punctures were an independent risk factor for renal function deterioration in a cohort of patients with solitary kidney.
Laparoscopic anatrophic nephrolithotomy for management of staghorn renal calculi. Combined minimally invasive percutaneous nephrolithotomy and retrograde intrarenal surgery for staghorn calculi in patients with solitary kidney.
Renal functional effects of multiple-tract percutaneous access. Blunt separation of parenchyma was done along the plane with back of Bard Parker knife handle. Percutaneous nephrolithotomy requiring multiple tracts: Smith et al[ 10 ] described the anatrophic nephrotomy and plastic calyrhaphy a procedure in which stone removal and correction of collecting system anomalies was possible.
Review on renal recovery after anatrophic nephrolithotomy: Are we really healing our patients?
Stone weight was grams Figure 6. A laparoscopic approach was not indicated because of the severe long standing COPD and previous open abdominal operations. Anatrophic Nephrolithotomy AN as proposed by Smith and Boyce in is the most preferred technique for such surgery [ 2 ]. There was no perioperative mortality. Find articles by Ananth Janarthan Kamath.
Factors affecting stone-free rate and complications of percutaneous nephrolithotomy for treatment of staghorn stone.
Anatrophic nephrotomy and plastic calyrhaphy. The anatrophic plane is defined by occluding the posterior segmental artery and administering methylene blue intravenously.
Studies on renal damage from percutaneous nephrolitholapaxy. There was no renal failure or new calculi during the follow up period.
Patient was turned to kidney position and parts were prepared and draped. Although excellent stone free rates can be achieved with ANL there are some drawbacks that may be of concern. Materials and Methods Between April and JulyAN was done in 14 renal units in 13 patients at our institute which is a tertiary care referral urological center.
Tree patients were submitted to preoperative 99mTc-DTPA renography to asses renal function 3 mo after surgery. Decreased renal function after percutaneous nephrolithotomy may occur because of parenchymal damage during needle puncture and tract dilation. Other authors also published their results regarding renal function.
Although parenchymal damage after anatrophic nephrolithotomy is of concern renal dysfunction is usually clinically insignificant. Anatrophic nephrolithotomy in the management of large staghorn renal calculi.
Postoperative evaluation in 16 out of 24 patients, seven out of 16 Stent removal was done in all patients between weeks. The advent of laparoscopic stone removing procedures has further reduced the need to amatrophic open surgery, even anatropgic nephrolithotomy [ 3 — 10 ]. Possible mechanisms related to increase in renal function are the relieve in obstruction, resolution of infection and inflammatory process, and compensatory hypertrophy of the remaining tissue[ 12 ].
